Fanning-out messages is a common technique to increase the scalability of background processing tasks. It involves publishing a message which is then consumed by multiple endpoints asynchronously. In AWS this can easily be achieved by combining the Amazon Simple Notification Service (Amazon SNS) with the Amazon Simple Queue Service (Amazon SQS).

Learning how to implement a fan-out scenario will increase your ability to build scalable and resilient solutions using Amazon Web Services.

In this lab, you will create a topic and some queues, you will configure them to work with each other, and you will test the fan-out scenario.

Learning Objectives

Upon completion of this beginner lab, you will be able to:

• Create an Amazon SNS topic
• Create an Amazon SQS queue
• Subscribe your Amazon SQS queues to your Amazon SNS topic
• Use the AWS command-line interface to test the fan-out scenario

Intended Audience
