AWS SNS (Simple Notification Service) combined with AWS SQS (Simple Queue Service) provides a scalable, flexible messaging system that allows decoupling of microservices, distributed systems, and serverless applications. SNS acts as a pub/sub messaging service that can fan out messages to multiple subscribers, including SQS queues, email endpoints, or Lambda functions. SQS offers reliable, persistent message queuing with at-least-once delivery, enabling components to process messages asynchronously and independently for resilient application architectures.
