We will look at some basic points of AWS Application Integration services like SQS, SNS and SWF.
SQS (Simple Queue Service)
1. Fully managed message queues for microservices, distributed systems, and serverless applications.
2. Enables application components and microservices to communicate with each other.
3. Pull based system
4. Queue Types: Standard and FIFO
5. Can be used with Redshift, DynamoDB, RDS, EC2, ECS, Lambda, S3 and SNS.
6. Multiple copies of every message are stored redundantly across multiple availability zones so that they are available whenever needed.
For more details, you can read documentation
SNS (Simple Notification Service)
1. Fully managed pub/sub messaging service for microservices, distributed systems, and serverless applications.
2. Push-based, many-to-many messaging.
3. Publishers to Topic: EC2, S3, RDS, CloudWatch
4. Subscribers to Topic: Serverless functions (Lambda), Queues (SQS), HTTP/S endpoints and distributed systems. Additionally, SNS fans out notifications to end users via mobile push messages, SMS, and email.
5. SNS uses cross availability zone message storage to provide high message durability.
6. SNS Topic owners can keep sensitive data secure by setting topic policies that restrict who can publish and subscribe to a topic.
SWF (Simple Workflow Service)
1. SWF lets you write your application components and coordination logic in any programming language and run them in the cloud or on-premises.
2. SWF creates a logical separation between tasks and components and acts as a task coordinator.
