OpenStack Workload Reference Architecture: Big Data
===================================================
Introduction
------------
Big Data analytics has established itself as an important process to support
new or enhanced business models. Big Data is a term for data sets that are so
large or complex that traditional data processing applications are inadequate
to deal with them. Big Data analytics refers to the use of predictive
analytics, user behavior analytics, or certain other advanced data analytics
methods that extract value from data.
Since Big Data analytics can include and analyze all types of data sources,
the results are valuable for most departments in an enterprise. Each might
perform analytics with different business objectives. Considering the short
innovation cycle of most digital business models, Enterprise IT is often
under pressure to fulfill a multitude of demands quickly. A flexible, fast,
efficient and easy-to-manage Big Data deployment is critical.
Cloud is one approach to tackle the dynamic situation caused by high volumes
of analytics requests with rapid deployment time requirements. In an
OpenStack-based cloud environment, a Big Data cluster can be provisioned in
an automated manner. The value of Big Data on cloud contributes to it being
one of the top use cases for OpenStack. According to the April 2016
`OpenStack User Survey`_, 27 percent of users have deployed or are testing
Big Data analytics solutions.
Apache Hadoop on OpenStack offers a Big Data infrastructure that scales out
both compute and storage resources, and provides the secure and automated
capabilities for the analytics process. The `Apache Hadoop project`_ is the
de facto standard open source framework for Big Data analytics, used in the
vast majority of deployments. Multiple Hadoop clusters are often deployed to
respond to an enterprise’s needs.
This reference architecture is intended for enterprise architects who are
looking to deploy Big Data Hadoop clusters on an OpenStack cloud. It describes
a generic Hadoop architecture and uses open source technologies:
* `OpenStack cloud software`_
* `Ubuntu Linux`_ operating system
* `Apache Ambari`_ – open source software to provision, manage and monitor
Hadoop clusters.
.. _OpenStack User Survey: https://www.openstack.org/assets/survey/April-2016-User-Survey-Report.pdf
.. _Apache Hadoop project: http://hadoop.apache.org/
.. _OpenStack cloud software: http://www.openstack.org/software/
.. _Ubuntu Linux: https://www.ubuntu.com/
.. _Apache Ambari: http://ambari.apache.org/
This reference architecture describes and includes installation files for a
basic Hadoop cluster. Additional services can be applied for a more complex
configuration and will be covered in future works.

OpenStack for Hadoop Clusters
-----------------------------
This Hadoop architecture is derived from actual use cases and experience.
Building a Hadoop-based Big Data environment can be a complex task. It is
highly recommended to use common approaches to reduce this complexity, such as
identifying the data processing models. These processing models demand high
availability of resources, networking, bandwidth, storage, as well as security
constraints in the enterprise context.
* **Batch processing model** – Analytics based on historic data
In the batch processing model, the analytic tasks are executed or queried in
a scheduled or recurring manner. Typically the data is already available for
analysis in a static repository such as large files or databases. The batch
processing model is often used to analyze business data of a certain period.
One example is an ETL (extract, transform, load) process to extract business
data from various ERP systems for supply chain planning.
* **Stream processing model** – Business real-time analytics
In the stream processing model, data is continuously streamed and directly
analyzed in real time. Actions can be triggered in case of occurrence of
special or defined events. An example of a stream processing workload is
fraud detection for credit card companies. A credit card transaction is
transmitted online to the credit card company and is evaluated in real time
based on certain parameters; for example, checking the card’s validity and
the purchase amount against the limit. It is also possible to check the
location of purchases and compare this to other recent purchases.
For example, if purchases are made in the U.S. and Europe in a timespan of
only a few hours, this indicates a high likelihood of fraud and action can be
taken to decline the transaction.
* **Predictive processing model** – Predict outcome based on recent and
historical data
This model is used to predict an outcome, behavior or other actions for the
future. Generally this analytic model consists of various predictive
algorithms. One example is predictive maintenance. Data from machines,
engines or other sensors is collected and analyzed so that predictive actions
can be made to recommend the next maintenance cycle before a failure might
occur.
Hadoop clusters use a master-slave architecture. The data is ingested into the
cluster and stored in blocks in the Hadoop distributed file system (HDFS). The
default block size is 64MB. The blocks of data are replicated to different
nodes in the clusters. Part of the core Hadoop project, `YARN`_ provides a
framework for job scheduling and cluster resource management. With YARN,
multiple data processing applications can be implemented in the Hadoop cluster.
.. _YARN: http://hortonworks.com/apache/yarn/
Typically a Hadoop cluster with YARN is composed of different types of cluster
nodes:
* **NameNode** – The metadata about the data blocks are stored in the NameNode.
This provides lookup functionality and tracking for all data or files in the
Hadoop cluster. NameNode does not store the actual data. Generally the
NameNode requires high memory (RAM) allocation. The NameNode belongs to the
"master" part of Hadoop architecture.
* **DataNode** – This is also referred as the worker node and belongs to the
"slave" part of a Hadoop architecture. It is responsible for storing and
computing the data and responds to the NameNode for filesystem operations.
Generally a DataNode requires high amount of storage space.
* **ResourceManager** – This is the master that manages the resources in the
Hadoop cluster. It has a scheduler to allocate resources to the various
applications across the cluster.
* **NodeManager** – This takes instruction from the ResourceManager and is
responsible for executing the applications. It monitors and reports the
resources (cpu, memory, disk) to the ResourceManager.
An OpenStack cloud is powered by many different services (also known as
projects). Utilizing the core services and the Hadoop Common package, a
Hadoop cluster can be deployed in a virtualized environment with minimal
effort. Optional services such as the OpenStack Orchestration service (Heat)
can be added to automate deployment. This reference architecture does not
cover OpenStack Big Data Service (Sahara). Sahara provides a simple means to
provision as well as scale previously provisioned Hadoop clusters.
Sahara will be covered in future reference architecture documents.
Figure 2 shows the core and optional services in relation to one another,
and the services to confirm are available in your OpenStack cloud.

Structuring a Hadoop Cluster with OpenStack
-------------------------------------------
OpenStack provides the necessary compute, network and data storage services
for building a cloudbased Hadoop cluster to meet the needs of the various
processing models.
Networking
**********
Multiple networks can be created for the Hadoop cluster connectivity. Neutron
routers are created to route the traffic between networks.
* **Edge Network** – Provides connectivity to the client-facing and enterprise
IT network. End users are accessing the Hadoop cluster through this network.
* **Cluster Network** – Provides inter-node communication for the Hadoop
cluster.
* **Management Network** – Optionally provides a dedicated network for
accessing the Hadoop nodes' operating system for maintenance and monitoring
purposes.
* **Data Network** – Provides a dedicated network for accessing the object
storage within an OpenStack Swift environment or to an external object
storage such as Amazon S3. This is optional if object storage is not used.
Neutron security groups are used to filter traffic. Hadoop uses different
ports and protocols depending on the services deployed and communications
requirements. Different security groups can be created for different types of
nodes, depending on the Hadoop services running on it. With OpenStack security
groups, multiple rules can be specified that allow/deny traffic from certain
protocols, ports, or IP addresses or ranges. Each virtual machine (VM) can be
applied with one or more security groups. In OpenStack, each tenant has a
default security group, which is applied to instances that have no other
security group defined. Unless changed, this security group denies all
incoming traffic.
Image Management
****************
There are multiple options to provide operating system configuration for the
Hadoop nodes. On-the-fly configuration allows greater flexibility but can
increase spawning time. The operating system images can also be pre-configured
to contain all of the Hadoop-related packages required for the different types
of nodes. Pre-configuration can reduce instance build time, but includes its
own set of problems, such as patching and image lifecycle management. In this
example, the Heat orchestration features are used to configure the Hadoop
nodes on-the-fly. Additional Hadoop and operating system packages are installed
on-the-fly depending on the node type (e.g. NameNode, DataNode). These packages
can be downloaded from Internet-based or local repositories. For a more secure
enterprise environment, local package repository is recommended.
Data Management
***************
Similar to an external hard drive, Cinder volumes are persistent block-storage
virtual devices that may be mounted and dismounted from the VM. Cinder volumes
can be attached to only one instance at a time. A Cinder volume is attached to
each Hadoop DataNode to provide the HDFS.
If the data to be processed by a Hadoop cluster needs to be accessed by other
applications, the OpenStack Swift object storage can be used to store it.
Swift offers a cost-effective way of storing unstructured data. Hadoop provides
a built-in interface to access Swift or AWS S3 object storage; either can be
configured to serve data over HTTP to the Hadoop cluster.
Orchestration
*************
Heat uses template files to automate the deployment of complex cloud
environments. Orchestration is more than just standing up virtual servers;
it can also be used to install software, apply patches, configure networking
and security, and more. Heat templates are provided with this reference
architecture that allow the user to quickly and automatically setup and
configure a Hadoop cluster for different data processing models
(types of analytics).
Figure 4: A Hadoop cluster on OpenStack
.. figure:: figures/figure04.png
:alt: Figure 4: A Hadoop cluster on OpenStack
Demonstration and Sample Code
-----------------------------
This section describes the Heat template provided for this workload. The
template is used to configure all of the Hadoop nodes. It has been created
for reference and training and is not intended to be used unmodified in a
production environment.
An Ambari Hadoop environment is created on a standard Ubuntu 14.04 server
cloud image in QEMU copy on write (qcow2). The qcow2 cloud image is stored in
the Glance repository. The Apache Ambari open source project makes Hadoop
management simpler by providing an easy-to-use Hadoop management web UI backed
by its RESTful APIs. Basically, Ambari is the central management service
for open source Hadoop. In this architecture, an Ambari service is installed
on the Master Node (NameNode). The Heat template also installs additional
required services such as the name server, Network Time Protocol (NTP) server,
database, and the operating system configuration customization required for
Ambari. Floating IP can be allocated to the Master Node to provide user access
to the Ambari service. In addition, an Ambari agent service is deployed on
each node of the cluster. This provides communication and authentication
functionality between the cluster nodes.
The following nodes are installed by the Heat template:
* **Master Node (NameNode)** – This node houses the cluster-wide management
services that provide the internal functionality to manage the Hadoop cluster
and its resources.
* **Data Nodes** – Services used for managing and analyzing the data, stored in
HDFS, are located on these nodes. Analytics jobs access and compute the data
on the Data Nodes.
* **Edge Node** – Services used to access the cluster environment or the data
outside the cluster are on this node. For security, direct user access to the
Hadoop cluster should be minimized. Users can access the cluster via the
command line interface (CLI) from the Edge Node. All data-import and
data-export processes can be channeled on one or more Edge Nodes.
* **Admin Node** – Used for system-wide administration
Multiple networks (edge, cluster, management, data) described in previous
sections are created by the Heat orchestration. A Neutron security group
is attached to each instance of the cluster node. The template also provisions
Cinder volumes and attaches one Cinder volume to each node. Swift is not
configured in this template and will be covered in future work.
The Heat template, BigData.yaml, can be downloaded from
http://www.openstack.org/software/sample-configs/#big-data.
Please review the README file for further details.
Scope and Assumptions
---------------------
The Heat template provided for this reference architecture assumes that the
Hadoop cluster workload is deployed in a single-region, single-zone OpenStack
environment. The deployment in a multi-zone/multiregion environment is outside
the scope of this document.
The Heat template is configured to address the minimum infrastructure
resources for deploying a Hadoop cluster. Architecting a Hadoop cluster is
highly dependent on the data volume and other performance indicators defined by
the business use cases, such as response times for analytic processes and how
and which services will be used.
The sample environment uses the Java environment. As such, the Heat template
installer will be required to accept the Java license agreement.
As mentioned, Sahara is not used in this implementation. Sahara is the
OpenStack Big Data Service that provisions a data-intensive application cluster
such as Hadoop or Spark. The Sahara project enables users to easily provision
and manage clusters with Hadoop and other data processing frameworks on
OpenStack. An update to this reference architecture to include Sahara is under
consideration.
Summary
-------
There are many possible choices or strategies for deploying a Hadoop cluster
and there are many possible variations in OpenStack deployment. This document
and the accompanying Heat templates serve as a general reference architecture
for a basic deployment and installation process via Openstack orchestration.
They are intended to demonstrate how easily and quickly a Hadoop Cluster can be
deployed, using the core OpenStack services. Complementary services will be
included in future updates.
These additional resources are recommended to delve into more depth on overall
OpenStack cloud architecture, the OpenStack services covered in this reference
architecture, and Hadoop and Ambari. The vibrant, global OpenStack community
and ecosystem can be invaluable for their experience and advice, especially the
users that have deployed Big Data solutions. Visit openstack.org to get started

Big Data Sample Heat Template
==============================
This heat templates deploy a Hadoop cluster with Apache Ambari.
Ambari is the central management service for Open Source Hadoop. It provides
central administration and management functionality via a web UI. In this
example, the Ambari service is installed on the MasterNode and an Ambari agent
is deployed on each DataNode in the cluster. This provides communication and
authentication functionality between the Hadoop cluster nodes.
**Type of roles in this Hadoop cluster**
====== ==================================================================
Role Details
====== ==================================================================
Master Master Node (aka Name Node) - this node houses the cluster-wide
management services that provide the internal functionality to manage
the Hadoop cluster and its resources.
Data Data Nodes – services used for managing and analyzing the data,
stored in HDFS, are located on these nodes. Analytics jobs access and
compute the data on the Data Nodes.
Edge Services used to access the cluster environment or the data outside
the cluster are on this node. For security, direct user access to the
Hadoop cluster should be minimized. Users can access the cluster via
the command line interface (CLI) from the Edge Node. All data-import
and data-export processes can be channeled on one or more Edge Nodes.
Admin Administrative Server - Used for system-wide administration.
====== ==================================================================
This template provision a small testing environment which demonstrate the
deployment of a Hadoop cluster in an OpenStack cloud environment. The
default settings used in this template should not be used without changes
in a production environment. Users are advised to change the settings that
fit in their own environment.
This template was tested using Mitaka & Liberty release of OpenStack.
-----------------
Heat File Details
-----------------
This template requires a few standard components such as an Ubuntu cloud image
and an external network for internet access.
The template prepares a few resources that are required by the Hadoop
deployment.
Multiple Cinder volumes are created for the Hadoop filesystem.
For simplicity, every node is attached with a Cinder volume with a default size
in this example.
Multiple Neutron subnets are created. This includes:
================== ======================
Subnet Details
================== ======================
Cluster Network Provides inter-node communication for the Hadoop cluster.
Data Network Provides a dedicated network for accessing the object
storage within an OpenStack Swift environment or to an
external object storage such as Amazon S3. This is
optional if object storage is not used.
Management Network Provides a dedicated network for accessing the Hadoop
nodes' operating system for maintenance and monitoring
purposes.
Edge Network Provides connectivity to the client-facing and enterprise
IT network. End users are accessing the Hadoop cluster
through this network.
================== ======================
Multiple routers are created to route the traffic between subnets.
Other networks can also be created depending on your specific needs.
Security Groups are defined and attached to every Node in the cluster.
Custom rules can be created for different types of nodes to allow/deny
traffic from certain protocols, ports or IP address ranges.
Next, the template creates a few servers of different roles (Master, Data,
Edge, Admin). An Ubuntu 14.04 cloud image is assumed to be used as the default
operating system of each servers.
When the server is booted, additional packages (depending on roles) are
installed and configured on each server. In this example, the Apache Ambari
is installed and all systems are configured with name server, ntp,
package repositories and other necessary settings for the Apache Ambari
service.
The Ambari Web UI can be accessed by pointing to the MasterNode's
IP address at port 8080. A Floating IP can be associated to the MasterNode.
-------------------------------
Running the heat template files
-------------------------------
You need to source the OpenStack credential file. You may download a copy of
the credential file from Horizon under Project>Compute>Access & Security>API
Access
Prior to running the template, please edit and change the default value of each
parameters to the one that match your own environment.
**Example to setup the Hadoop cluster environment**::
openstack stack create --template BigData.yaml HadoopCluster

Web Applications Reference Architecture Sample Heat Template
============================================================
These heat templates deploy WordPress on a 3-Tier LAMP architecture. There are
two versions of the primary template, one which creates a static environment
which does not require ceilometer, and one which provides autoscaling of the
web and application tiers based on CPU load, which does require ceilometer.
**The WordPress 3-Tier LAMP Architecture Sample**
====== ====================== =====================================
Tier Function Details
====== ====================== =====================================
Web Reverse Proxy Server Apache + mod_proxy
App WordPress Server Apache, PHP, MySQL Client, WordPress
Data Database Server MySQL
====== ====================== =====================================
**NOTE:** The sample WordPress application was tested with CentOS7 and
Ubuntu Trusty and Ubuntu Xenial.
-----------------
Heat File Details
-----------------
The template uses a nested structure, with two different primary yaml files,
both of which utilize the same 4 nested files. The templates were tested using
Newton release of OpenStack, and Ubuntu server 14.04 and Centos7.
**WebAppStatic.yaml:** If you want a static environment, run this yaml file.
This will create a static environment, with two load balanced web servers, and
two load balanced application servers, and a single database server using
cinder block storage for the database files.
REQUIRED PARAMETERS:
* ssh_key_name, image_id, public_network_id
OPTIONAL PARAMETERS:
* db_instance_flavor, app_instance_flavor, web_instance_flavor,
db_server_name, app_server_name, web_server_name, dns_nameserver
**WebAppAutoScaling.yaml:** If you want a dynamic autoscaling environment,
run this yaml file. This yaml files sets up heat autoscaling groups.
REQUIRED PARAMETERS:
* ssh_key_name, image_id, public_network_id
OPTIONAL PARAMETERS:
* db_instance_flavor, app_instance_flavor, web_instance_flavor,
db_server_name, app_server_name, web_server_name, dns_nameserver
The following 4 yaml files are called by the primary files above, and are by
default expected to be in a nested subdirectory:
**setup_net_sg.yaml:** This file creates 3 separate private networks, one for
each tier. In addition it creates two load balancers (using neutron LBaaS V2),
one which has a public IP that connects the web private network to the public
network, and one with a private IP that connects the web network to the
application network. The template also creates a router connecting the
application network to the database network. In addition to the networks and
routers, the template creates 3 security groups, one for each of the tiers.
**heat_web_tier.yaml:** This template file launches the web tier nodes.
In addition to launching instances, it installs and configures Apache and
Apache modproxy which is used to redirect traffic to the application nodes.
**heat_app_tier.yaml:** This template file launches the application tier nodes.
In addition to launching the instances, it installs Apache, PHP, MySQL client,
and finally WordPress.
**heat_sql_tier.yaml:** This template file launches the database tier node and
installs MySQL. In addition it creates a cinder block device to store the
database files. The template also creates the required users and databases for
the WordPress application.
-------------------------------
Running the heat template files
-------------------------------
First you need to source your credential file. You may download a copy of the
credential file from Horizon under Project>Compute>Access & Security>API Access
**Example to setup the static environment**::
openstack stack create --template WebAppStatic.yaml --parameter ssh_key_name=mykey --parameter image_id=ubuntu --parameter dns_nameserver="8.8.8.8,8.8.4.4" --parameter public_network_id=external_network ThreeTierLAMP
**Example to setup the autoscaling environment**::
openstack stack create --template WebAppAutoScaling.yaml --parameter ssh_key_name=mykey --parameter image_id=centos --parameter dns_nameserver="8.8.8.8,8.8.4.4" --parameter public_network_id=external_network ThreeTierLAMP

heat_template_version: 2016-10-14
#The value of heat_template_version tells Heat not only the format of the template but also features that will be validated and supported
#2016-10-14 represents the Newton release
description: >
This is the main Heat template for the Web Applications Workload Reference
Architecture created by the Enterprise Working Group.
This version of the template does not include autoscaling, and does not require ceilometer.
This template calls multiple nested templates which actually do the
majority of the work. This file calls the following yaml files in a ./nested subdirectory
setup_net_sg.yaml sets up the security groups and networks for Web, App, and Database
heat_app_tier.yaml starts up application servers and does on-the-fly builds
heat_web_tier.yaml starts up web servers and does on-the-fly builds
heat_sql_tier.yaml starts up mysql server and does on-the-fly builds.
NOTE: This serves as a guide to new users and is not meant for production deployment.
REQUIRED YAML FILES:
setup_net_sg.yaml, heat_app_tier.yaml, heat_sql_tier.yaml, heat_web_tier.yaml
REQUIRED PARAMETERS:
ssh_key_name, image_id, public_network_id
OPTIONAL PARAMETERS:
db_instance_flavor, app_instance_flavor, web_instance_flavor, db_server_name, app_server_name, web_server_name, dns_nameserver

OpenStack Workload Reference Architecture: Web Applications
===========================================================
Introduction
------------
Web applications are the most prevalent applications in business today. They
are driven by user interaction over the Internet using a web browser front-end.
Common web applications include webmail, online retail sales, online auctions,
online banking, instant messaging services, and more.
Web applications are typically characterized by IT resource requirements that
fluctuate with usage, predictably or unpredictably. Failure to respond to
either can impact customer satisfaction and sales. An automatically scaling web
application and underlying infrastructure can be essential. Unlike a
traditional, static environment, cloud computing allows IT resources to scale
dynamically, both up and down, based on the application-generated load
(CPU utilization, memory, etc.).
The OpenStack cloud platform offers auto-scaling for web applications as well
as a comprehensive platform for all IT applications, offering agility and
cost-effectiveness. OpenStack is open source cloud software that controls large
pools of compute, storage, and networking resources throughout a datacenter,
all managed through a dashboard or API. Thousands of enterprises use OpenStack
to run their businesses every day.
Intended for enterprise IT architects, this reference architecture describes
the architecture and services required by a simple three-tier web application,
using popular LAMP software on an OpenStack cloud. LAMP consists of Linux,
Apache, MySQL, and PHP/Python/Perl and is considered by many as the platform of
choice for development and deployment of high performance web applications.
We identify and recommend the required and optional OpenStack services for both
a static virtualized implementation and a fully dynamic auto-scaling
implementation. Lastly, we will provide tested implementation files you can
use to install and instantiate an OpenStack web application environment using
Wordpress as the sample application. These files are Heat templates that will
create the virtual servers for each tier, networking, load balancing, and
optionally, auto-scaling.
Figure 1: Three-tier web application architecture overview
.. figure:: figures/figure01.png
:alt: Figure 1: Three-tier web application architecture overview
OpenStack for Web Applications
------------------------------
A three-tier web application consists of the web presentation, the
application, and persistent database tiers.
- Web presentation tier – cluster of web servers that will be used to render
either static or dynamically generated content for the web browser.
- Application tier – cluster of application servers that will be used to
process content and business logic.
- Database tier – cluster of database servers that store data persistently.
An OpenStack cloud is powered by many different services (also known as
projects). Utilizing only the **core services**, a three-tier web services
application can be deployed in a virtualized environment that can be
**manually** scaled up and down as required with minimal effort.
**Optional services** can be added for more functionality:
- OpenStack Orchestration service (Heat project) allows automating workload
deployment.
- Together, Orchestration and Telemetry (Ceilometer) enable dynamic scaling as
load increases and decreases.
- OpenStack Database service (Trove) provides Database-as-a-Service (DBaaS) to
automate database provisioning and administration. Trove is an option for
web applications on OpenStack but is not used in this basic reference
architecture.
Figure 2 shows the core and optional services in relation to one another, and
the services to confirm are available in your OpenStack cloud.

Brief descriptions of the core and optional services used for simple
three-tier web applications follow. The `OpenStack Project Navigator <http://www.openstack.org/software/project-navigator/>`_
provides additional information.
.. list-table:: **Core services**
:widths: 20 50
* - Compute (Nova)
- Manages the life cycle of compute instances, including spawning,
scheduling, and decommissioning of virtual machines (VMs) on demand.
* - Image Service (Glance)
- Stores and retrieves VM disk images. Used by OpenStack Compute during
instance provisioning.
* - Block Storage (Cinder)
- Virtualizes the management of block storage devices and provides a
self-service API to request and use those resources regardless of the
physical storage location or device type. Supports popular storage
devices.
* - Networking (Neutron)
- Enables network connectivity as a service for other OpenStack services,
such as OpenStack Compute. Provides an API to define networks and their
attachments. Supports popular networking vendors and technologies. Also
provides LBaaS and Firewall-as-a-Service (FWaaS).
* - Identity Service (Keystone)
- Provides authentication and authorization for the other OpenStack
services.
* - Object Storage (Swift)
- Stores and retrieves arbitrary unstructured data objects via a RESTful
HTTP-based API. Highly fault-tolerant with data replication and
scale-out architecture.
* - Dashboard (Horizon)
- Provides an extensible web-based self-service portal to interact with
underlying OpenStack services, such as launching an instance, assigning
IP addresses, or configuring access controls.
.. list-table:: **Optional services**
:widths: 20 50
* - Orchestration (Heat)
- Orchestrates multiple composite cloud applications by using either the
native HOT template format or the AWS CloudFormation template format,
through both an OpenStack-native REST API and a
CloudFormation-compatible Query API.
* - Telemetry (Ceilometer)
- Monitors and meters the OpenStack cloud for billing, benchmarking,
scalability, and statistical purposes.
* - Database (Trove)
- A database-as-a-service that provisions relational and non-relational
database engines.
Figure 3 illustrates the basic functional interaction between these services.

Structuring an OpenStack Web Application
----------------------------------------
Generally a three-tier web application consists of a web presentation tier,
application tier, and persistent database tier. This chapter discusses these
and additional architectural components and considerations for an
OpenStack-based web application.
.. list-table::
:widths: 20 50
:header-rows: 1
* - Architectural Components
- Description
* - Web presentation tier
- A cluster of web server used to render static or dynamically generated
content for the web browser.
* - Application tier
- A cluster of application servers used to process content and business
logic.
* - Database tier
- A cluster of database servers used to store data persistently.
* - Load balancers
- Two load balancers are required to equally distribute load. The first
load balancer distributes the web traffic at the presentation tier. A
separate load balancer is required to distribute the load among the
application servers.
* - Relational Database Management System (RDBMS)
- The database tier used in this example uses a master/slave RDBMS
configuration. Data is kept in persistent block storage and backed-up
periodically.
* - Firewalls
- For security, a set of firewall rules must be enforced at each tier.
* - Network configuration
- The network must be configured to filter unnecessary traffic at
different tiers.
* - Auto-scaling
- Auto-scaling is desirable to automatically respond to unexpected
traffic spikes and resume to normal operation when the load decreases.
Figure 4: OpenStack web application architecture
.. figure:: figures/figure04.png
:alt: Figure 4: OpenStack web application architecture
Load balancing
**************
Load balancing can be based on round robin, least connections, or random. If the
application is not cloud-native and needs to maintain session state,
Load-Balancing-as-a-Service (LBaaS) can be configured to always direct the
equest to the same VMs. Neutron allows for proprietary and open-source LBaaS
technologies to drive load balancing of requests, allowing the OpenStack
operator to choose. Neutron LBaaS V1.0, is used for this reference
architecture. V2.0 is available with the OpenStack Liberty release and supports
Octavia as well as HAProxy backends. An alternative to Neutron LBaaS is to
setup a software load balancer by launching instances with HAProxy.
Image management
****************
There are multiple options and tools to provide configuration of servers when
spawning instances of the web, application, and database VMs. On-the-fly
configuration allows greater flexibility but can increase spawning time. The
images can also be pre-configured to contain all of the files, packages and
patches required to boot a fully operational instance. Pre-configuration can
reduce instance build time, but includes its own set of problems, such as
patching and keeping licenses up to date. For this example, the orchestration
features built into Heat are used to spawn and configure the three tiers of
servers on-the-fly.
Persistent storage
******************
Similar to an external hard drive, Cinder volumes are persistent block-storage
virtual devices that may be mounted and dismounted from the VM by the operating
system. Cinder volumes can be attached to only one instance at a time. This
reference architecture creates and attaches a Cinder volume to the database VM
to meet the data persistency requirements for the database tier. In the case of
a database VM failure, a new VM can be created and the Cinder volume can be
re-attached to the new VM.
Swift provides highly available, distributed, eventually-consistent
object/BLOB storage. Unlike a physical device, Swift storage is never mounted
to the instance. Objects and metadata are created, modified, and obtained using
the Object Storage API, which is implemented as a set of REpresentational State
Transfer (REST) web services. If the web application requires hosting of static
content (e.g. image, video), use Swift to store it, and configure Swift to
serve the content over HTTP. In this reference architecture, Swift is also used
for storing and archiving the database backup files.
Network subnets
***************
For this workload, Neutron is used to create multiple subnets, one for each
tier: a web subnet, an application subnet, and a data subnet. Neutron routers
are created to route traffic between the subnets.
Network security
****************
Filtering of inbound traffic is done through the use of security groups.
Different security groups can be created and applied to the instances in each
tier to filter unnecessary network traffic. OpenStack security groups allow
specification of multiple rules to allow/deny traffic from certain protocols,
ports, or IP addresses or ranges. One or more security groups can be applied
to each instance. All OpenStack projects have a "default" security group, which
is applied to instances that have no other security group defined. Unless
changed, the default security group denies all incoming traffic.
Orchestration
*************
Heat uses template files to automate the deployment of complex cloud
applications and environments. Orchestration is more than just standing up
virtual servers. It can also be used to install software, apply patches,
configure networking and security, and more. The Heat templates provided with
this reference architecture allow the user to quickly and automatically setup
and configure a LAMP-based web services environment.
Auto-scaling
************
The ability to scale horizontally is one of the greatest advantages of cloud
computing. Using a combination of Heat orchestration and Ceilometer, an
OpenStack cloud can be configured to automatically launch additional VMs for
the web and application tiers when demand exceeds preset thresholds. Ceilometer
performs the system resource monitoring and can be configured to alarm when
thresholds are exceeded. Heat then responds to the alarm according to the
configured scale-up policy. Scaling can also be done in the opposite direction,
reducing resources when the demand is low, saving money.
Demonstration and Sample Code
-----------------------------
This section describes the Heat templates provided as resources for this
workload. They have been created for reference and training and are not
intended to be used unmodified in a production environment.
The Heat templates demonstrate how to configure and deploy WordPress, a
popular web application, on a three-tier LAMP architecture. There are two
versions of the primary template: one that creates a static environment
(manual scaling) and one that integrates with Ceilometer to provide
auto-scaling of the web and application tiers based on CPU load.
The Heat templates can be downloaded from
http://www.openstack.org/software/sample-configs#webapplications

Heat file details
*****************
The Heat template uses a nested structure, with two different primary yaml
files, both of which use the same four nested files. The files contain inline
comments identifying possible issues and pitfalls when setting up the
environment. The templates were tested using Mitaka release of OpenStack, and
Ubuntu server 14.04 and Centos 7.
**WebAppStatic.yaml:** Run this yaml file for a static environment. It creates
a static environment with two load-balanced web servers, two load-balanced
application servers, and a single database server using Cinder block storage
for the database. This yaml file utilizes Heat resource groups to call
heat_app_tier.yaml and heat_web_tier.yaml, launching multiple copies of the web
and application servers.
**WebAppAutoScaling.yaml:** For a dynamic auto-scaling environment, run this
yaml file. It sets up Heat auto-scaling groups and Ceilometer alarms for both
the web and application tiers. The high-CPU Ceilometer alarms are configured by
default to add an instance when the average CPU utilization is greater than 50%
over a five-minute period. The low CPU alarms are configured to remove an
instance when the average CPU utilization drops below 20%. When configuring
Ceilometer CPU alarms, it's important to keep in mind that the alarm by default
looks at the average CPU utilization over all instances in the OpenStack
project or tenant. Metadata can be used to create unique tags to identify
groups of nodes, and then have the alarm trigger only when the average CPU
utilization of the group exceeds the threshold. Ceilometer does not look at the
CPU utilization on each of the instances; only the average utilization is
reported. Another very important tip: ensure the selected "period" used to
monitor the nodes is greater than the sampling rate configured in
/etc/ceilometer/pipeline.config file. If the sampling rate is higher than the
period, the alarm will never be activated.
The following yaml files are called by the primary files above:
- **setup_net_sg.yaml:** This is the first file called by the main templates.
This file creates three separate private networks, one for each tier. In
addition, it creates two load balancers (using Neutron LBaaS V1.0): one with
a public IP that connects the web tier private network to the public network,
and one with a private IP that connects the web tier network to the
application tier network. The template also creates a router connecting the
application network to the database network. In addition to the networks and
routers, the template creates three security groups, one for each of the
tiers.
- **heat_web_tier.yaml:** This template file launches the web tier nodes. In
addition to launching instances, it installs and configures Apache and Apache
modproxy, which is used to redirect traffic to the application nodes.
- **heat_app_tier.yaml:** This template file launches the application tier
nodes. In addition to launching the instances, it installs Apache, PHP, MySQL
client, and finally WordPress.
- **heat_sql_tier.yaml:** This template file launches the database tier node.
It also creates a Cinder block device to store the database files, and the
required users and databases for the WordPress application.
Scope and Assumptions
---------------------
The Heat templates provided and described above assume that the three-tier web
application workload is deployed in a single-region, single-zone OpenStack
environment. If the actual application requires higher SLA commitment, it is
recommended to deploy OpenStack in a multi-zone, multi-region environment. This
deployment is out of the scope of this reference architecture and will be
described in a separate one.
As mentioned, Trove is not used in this implementation at this time. Trove is
OpenStack DBaaS that provisions relational and non-relational database engines.
An update to this reference architecture to include Trove is under
consideration.
Another OpenStack service that would be suitable for the
three-tier architecture would be Neutron Firewall-as-a-Service (FWaaS). FWaaS
operates at the perimeter by filtering traffic at the Neutron router. This
distinguishes it from security groups, which operate at the instance level.
FWaaS is also under consideration for a future update.
Summary
-------
There are many strategies for deploying a three-tier web application and there
are choices for each OpenStack deployment. This reference architecture is meant
to serve as a general guide to be used to deploy the LAMP stack on an OpenStack
cloud using core and selected optional services. The Heat orchestration service
is used; however, popular third-party deployment products such as Chef, Puppet,
or Ansible can also be used. Other OpenStack services can be selected to
enhance this basic architecture with additional capabilities.
This document shows how easily and quickly a three-tier LAMP and Wordpress
environment can be implemented using just a few OpenStack services. We offer
the Heat templates to help you get started and become familiar with OpenStack.
These additional resources are recommended to delve into more depth on overall
OpenStack cloud architecture, and the components and services covered in this
reference architecture. The vibrant, global OpenStack community and ecosystem

eCommerce Sample Heat Template
==============================
These heat templates deploy OpenCart on a 3-Tier LAMP architecture. There are
two versions of the primary template, one which creates a static environment
which does not require ceilometer, and one which provides autoscaling of the
web and services layers based on CPU load, which does require ceilometer.
**The OpenCart 3-Tier LAMP Architecture Sample**
======== ====================== ====================================
Layer Function Details
======== ====================== ====================================
Web Reverse Proxy Server Apache + mod_proxy
Services Application Server Apache, PHP, MySQL Client, OpenCart
Data Database Server MySQL
======== ====================== ====================================
-----------------
Heat File Details
-----------------
The template uses a nested structure, with two different primary yaml files,
both of which utilize the same 4 nested files. The templates were tested
using the Newton release of OpenStack, and Ubuntu Trusty and Xenial, and Centos7.
**eCommerceStatic.yaml:** If you want a static environment, run this yaml
file. This will create a static environment, with two load balanced web
servers, and two load balanced application servers, and a single database
server using cinder block storage for the database files.
REQUIRED PARAMETERS:
* ssh_key_name, image_id, public_network_id
OPTIONAL PARAMETERS:
* db_instance_flavor, app_instance_flavor, web_instance_flavor,
db_server_name, db_name, db_username, db_password, db_root_password,
app_server_name, web_server_name, admin_username, admin_password,
admin_email, dns_nameserver
**eCommerceAutoScaling.yaml:** If you want a dynamic autoscaling environment,
run this yaml file. This yaml files sets up heat autoscaling groups.
REQUIRED PARAMETERS:
* ssh_key_name, image_id, public_network_id
OPTIONAL PARAMETERS:
* db_instance_flavor, app_instance_flavor, web_instance_flavor,
db_server_name, db_name, db_username, db_password, db_root_password,
app_server_name, web_server_name, admin_username, admin_password,
admin_email, dns_nameserver
The following 4 yaml files are called by the primary files above, and are by
default expected to be in a nested subdirectory:
**setup_network.yaml:**
This file creates 3 separate private networks, one for each tier. In
addition it creates two load balancers (using neutron LBaaS V2), one which
has a public IP that connects the web private network to the public
network, and one with a private IP that connects the web network to the
services network. The template also creates a router connecting the
services network to the database network. In addition to the networks and
routers, the template creates 3 security groups, one for each of the tiers.
**launch_web_layer.yaml:**
This template file launches the web layer nodes. In addition to launching
instances, it installs and configures Apache and Apache modproxy which is
used to redirect traffic to the application nodes.
**launch_services_layer.yaml:**
This template file launches the services layer nodes. In addition to
launching the instances, it installs Apache, PHP, MySQL client, and
OpenCart.
**launch_sql_layer.yaml:**
This template file launches the database layer node and installs MySQL.
In addition it creates a cinder block device to store the database files.
The template also creates the required users and databases for the OpenCart
application.
-------------------------------
Running the heat template files
-------------------------------
First you need to source your credential file. You may download a copy of the
credential file from Horizon under Project>Compute>Access & Security>API
Access
**Example to setup the static environment**::
openstack stack create --template eCommerceStatic.yaml --parameter ssh_key_name=mykey --parameter image_id=ubuntu --parameter dns_nameserver="8.8.8.8,8.8.4.4" --parameter public_network_id=external_network OpenCart
**Example to setup the autoscaling environment**::
openstack stack create --template eCommerceAutoScaling.yaml --parameter ssh_key_name=mykey --parameter image_id=centos --parameter dns_nameserver="8.8.8.8,8.8.4.4" --parameter public_network_id=external_network OpenCart

description: >
This is the main Heat template for the eCommerce Workload Architecture created by the
Enterprise Working Group. This template contains the autoscaling code and calls nested
templates which actually do the majority of the work. Ceilometer is required in order to
run this template. This file calls the following yaml files in a ./nested subdirectory

launch_services_layer.yaml starts up application servers and does on-the-fly builds
launch_web_layer.yaml starts up web servers and does on-the-fly builds
launch_sql_layer.yaml starts up mysql server and does on-the-fly builds.
NOTE: This serves as a guide to new users and is not meant for production deployment.

#The value of heat_template_version tells Heat not only the format of the template but also features that will be validated and supported
#2016-04-08 represents the Newton release
description: >
This is the main Heat template for the eCommerce Workload Architecture created by the
Enterprise Working Group. This version of the template does not include autoscaling,
and does not require ceilometer.
This template calls multiple nested templates which actually do the
majority of the work. This file calls the following yaml files in a ./nested subdirectory
setup_network.yaml sets up the security groups and networks for Web, App, and Database
launch_services_layer.yaml starts up application servers and does on-the-fly builds
launch_web_layer.yaml starts up web servers and does on-the-fly builds
launch_sql_layer.yaml starts up mysql server and does on-the-fly builds.
NOTE: This serves as a guide to new users and is not meant for production deployment.
REQUIRED YAML FILES:
setup_network.yaml, launch_services_layer.yaml, launch_sql_layer.yaml, launch_web_layer.yaml
REQUIRED PARAMETERS:
ssh_key_name, image_id, public_network_id
OPTIONAL PARAMETERS:
db_instance_flavor, app_instance_flavor, web_instance_flavor, db_server_name, db_name
db_username, db_password, db_root_password, app_server_name, web_server_name, admin_username
admin_password, admin_email, dns_nameserver

This is a nested Heat used by the E-Commerce Architecture Workload reference document
created by the Enterprise Working Group. These templates demonstrate a sample
LAMP architecture supporting Wordpress. This template installs and configures
Apache and Apache modproxy which is used to redirect traffic to the application nodes.
This serves as a guide to new users and is not meant for production deployment.

OpenStack Workload Reference Architecture: <workload-name>
==========================================================
Introduction
------------
This section provides detailed information on what the workload is.
Please include a high-level overview diagram whenever possible.
OpenStack for <workload>
------------------------
This section provides detailed information on which OpenStack services
are required to support this workload.
Please include all **core** and **optional** services.
Please provide a brief description of each services used in this document.
For example:
.. list-table:: **Core services**
:widths: 20 50
* - Compute (Nova)
- Manages the life cycle of compute instances, including spawning,
scheduling, and decommissioning of virtual machines (VMs) on demand.
* - Object Storage (Swift)
- Stores and retrieves arbitrary unstructured data objects via a RESTful
HTTP-based API. Highly fault-tolerant with data replication and
scale-out architecture.
Please include a logical representation diagram and a functional interaction
diagram of the OpenStack services whenever possible.
Structuring a <workload> with OpenStack
---------------------------------------
This section provides detailed information on the workload requirements and
specify how each of the OpenStack services (mentioned in previous section)
are used to satisfy the workload requirements.
Please include a diagram of the deployment architecture whenever possible.
Demonstration and Sample Code
-----------------------------
Every workload must be accompanied by at least one sample code that can be
used to provision such workload environment. This can be either Heat template,
Murano packages, or other code (e.g. ansible)
This section provides a brief summary of the sample code. You do not need to
explain every single step in the sample code. However, please provide
sufficient information to explain what the sample code is trying to achieve.
Scope and Assumptions
---------------------
This section describes the specific scope, limitation or assumption made for
this workload reference architecture.
For example: The Heat template provided for this reference architecture
assumes that the web application workload is deployed in a single-region,
single-zone OpenStack environment. The deployment in a multi-zone/multi-region
environment is outside the scope of this document.
Summary
-------
This section concludes the document.
