SQS (Simple Queue Service) – AWS’s message queuing service.
Amazon SQS is a fully managed message queuing service that enables decoupling and scaling of distributed systems and applications. It offers two queue types: standard queues for maximum throughput and FIFO queues for exactly-once processing. SQS features message retention up to 14 days, visibility timeout for message processing, and dead-letter queues for handling failed messages. The service includes server-side encryption, access policy language, and cost optimization through long polling. It supports batch operations and integrates with Lambda for serverless architectures.
