api
DC Manager API is Web Server Gateway Interface (WSGI) application to receive and process API calls, including keystonemiddleware to do the authentication, parameter check and validation, convert API calls to job rpc message, and then send the job to DC Manager Manager through the queue. If the job will be processed by DC Manager Manager in synchronous way, the DC Manager API will wait for the response from the DC Manager Manager. Otherwise, the DC Manager API will send response to the API caller first, and then send the job to DC Manager Manager in asynchronous way.
Multiple DC Manager API could run in parallel, and also can work in multi-worker mode.
Multiple DC Manager API will be designed and run in stateless mode, persistent data will be accessed (read and write) from the DC Manager Database through the DAL module.
