Application Integration at AWS

Integrate microservices, distributed systems, and serverless applications

Modern applications are composed of small, independent building blocks that are easier to develop, deploy, and maintain. Application integration services enable communication between decoupled components within microservices, distributed systems, and serverless applications so you can easily build scalable and more resilient solutions. With a suite of services for message queuing, publishing and subscribing to topics, application orchestration, and GraphQL APIs, AWS enables integration within nearly any application.

Publish – Subscribe Messaging
Amazon SNS is a fully managed pub/sub messaging service that enables you to decouple microservices, distributed systems, and serverless applications. Using Amazon SNS topics, publishers can fanout messages to many subscriber endpoints, including Amazon SQS queues, AWS Lambda functions, HTTP/S webhooks, mobile push, SMS, and email.
 
Use case: Publish push messages to a variety of endpoint types subscribed to one or many Amazon SNS topics.

Message Queues – Standard APIs
Amazon MQ is a managed message broker service for Apache ActiveMQ that makes it easy to set up and operate a message broker in the cloud. Connecting your current applications to Amazon MQ is easy because it uses industry-standard APIs and protocols including JMS, NMS, AMQP, STOMP, MQTT, and WebSocket.
 
Use Case: Decouple and scale microservice and distributed systems on premises or in the cloud using standard APIs.
 
AppSync_70x70
GraphQL Serverless API
AWS AppSync simplifies application development by letting you create a flexible API to securely access, manipulate, and combine data from one or more data sources. It is a managed service that uses GraphQL to make it easy for applications to get exactly the data they need.
 
 
Use case: Build scalable applications, including those requiring real-time updates and offline data access, on a range of data sources such as NoSQL data stores, relational databases, HTTP APIs, and AWS Lambda.

Application Orchestration & Workflow

AWS Step Functions is a fully managed service that makes it easy to coordinate the components of distributed applications and microservices using visual workflows, so you can build and update apps quickly. Using Step Functions, you can stitch together services such as AWS Lambda and Amazon ECS into feature-rich applications.

Use case: Connect and coordinate distributed components, microservices and serverless applications.

Serverless Event Bus
Amazon EventBridge is a serverless event bus that makes it easy to connect applications together using data from your own applications, Software-as-a-Service (SaaS) applications, and AWS services. EventBridge delivers a stream of real-time data from event sources, such as Zendesk, Datadog, or Pagerduty, and routes that data to targets like AWS Lambda.
 
Use Case: Ingest data changes from a SaaS app like Zendesk and route them to AWS Lambda for processing.
