AWS Serverless Microservices with Patterns and Best Practices - What Is Amazon SQS?

Amazon SQS is a fully managed message queuing service that helps decouple and scale microservices, distributed systems, and service applications. It simplifies the management of message-oriented middleware, allowing developers to focus on their core tasks. SQS supports two types of message queues: Standard queues, which offer maximum throughput and at least once delivery, and FIFO queues, which ensure messages are processed exactly once in the order sent. SQS provides a secure, durable, and available hosted queue with integration options and a generic web service API accessible via various programming languages.
