Amazon Simple Queue Service (SQS) is a fully managed message queuing service provided by AWS. It enables you to decouple and scale microservices, distributed systems, and serverless applications.

Question 8

Difference between SQS, SNS, and MQ?

Answer 8

Amazon SQS decouples and scales distributed software systems and components as a queue service.

Amazon SNS allows publishers to send messages to multiple subscribers through topics, which serve as communication channels. Subscribers receive published messages using a supported endpoint type, such as Amazon Data Firehose, Amazon SQS, Lambda, HTTP, email, mobile push notifications, and mobile text messages (SMS).

Amazon MQ fits best with enterprises looking to migrate from traditional message brokers, supporting standard messaging protocols like AMQP and MQTT, along with Apache ActiveMQ and RabbitMQ. It offers compatibility with legacy systems needing stable, reliable messaging without significant reconfiguration.
