Description
Simple Notification Service (SNS) is a managed service that provides message delivery from publishers to subscribers (also known as producers and consumers). Amazon Simple Queue Service (SQS) is a managed message queuing service technical professionals and developers use to send, store and retrieve multiple messages of various sizes asynchronously. Using Amazon SNS and Amazon SQS together, messages can be delivered to applications that require immediate notification of an event, and also persisted in an Amazon SQS queue for other applications to process at a later time.
