AWS alternative
AWS services like SNS Simple Notification Service) and SQS (Simple Queue Service) could be used together to accomplish the notification based messaging system, but to not get tied to a single vendor, we are using the standard based messaging service, that is JMS (Java Message Service). The intent is to stick to the JMS API specifications and not use implementation/vendor specific features and extensions, thus leaving the window open to switch brokers if the need be.
