5. Application Integration

AWS Step Functions

  • AWS Step Functions lets you coordinate multiple AWS services into serverless workflows so you can build and update apps quickly. 
  • Using Step Functions, you can design and run workflows that stitch together services such as AWS Lambda and Amazon ECS into feature-rich applications.

Amazon MQ

  • Amazon MQ is a managed message broker service for Apache ActiveMQ that makes it easy to set up and operate message brokers in the cloud
  • Message brokers allow different software systems–often using different programming languages, and on different platforms–to communicate and exchange information.

Amazon SQS

  • SQS is apull based service.
  • Messages are kept in queue from 1 minute to 14 days, defult retention period is 4 days.
  • Amazon Simple Queue Service (Amazon SQS) is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications
  • Using SQS, you can send, store, and receive messages between software components at any volume, without losing messages or requiring other services to be available.
  • SQS offers two types of message queues
    • Standard queues offer maximum throughput, best-effort ordering, and at-least-once delivery. 
    • SQS FIFO queues are designed to guarantee that messages are processed exactly once, in the exact order that they are sent.

Amazon SNS

  • Amazon Simple Notification Service (Amazon SNS) is a highly available, durable, secure, fully managed pub/sub messaging service that enables you to decouple microservices, distributed systems, and serverless applications
  • Amazon SNS provides topics for high-throughput, push-based, many-to-many messaging. 
  • Using Amazon SNS topics, your publisher systems can fan out messages to a large number of subscriber endpoints for parallel processing,

Amazon SWF

  • Amazon Simple Workflow (Amazon SWF) helps developers build, run, and scale background jobs that have parallel or sequential steps
