Best Message-Oriented Middleware for Appmixer

Amazon Simple Notification Service is a fully managed messaging platform that allows for system-to–system and app-to–person (A2P), communication. It allows you to communicate between systems using publish/subscribe patterns (pub/sub), which allow messaging between decoupled microservice apps. You can also communicate directly with users via SMS, mobile push, and email. The system-to–system pub/sub functionality allows for topic-based, high-throughput push-based, many–to-many messaging. Your publisher systems can use Amazon SNS topics to fanout messages to large numbers of customer endpoints or subscriber systems, including Amazon SQS queues and AWS Lambda functions. You can send messages to large numbers of users using the A2P messaging functionality. This allows you to use either a pub/sub or direct-publish message using one API.
