Amazon Simple Notification Service (SNS) is a fully-managed, highly-scalable service that facilitates message delivery using a publish/subscribe model. You can use Amazon Simple Notification Service (SNS) to send messages to email recipients, webhooks, or mobile devices via SMS or push notifications.
With Amazon SNS, you can deliver an unlimited number of notifications without worrying about scaling up. You can use AWS Lambda to customize how messages are processed and integrate messaging with your other AWS resources or 3rd-party services.
In this Lab, you will learn how to process SNS notifications with a Lambda Function. As a simple example, you will use Python to upload a file to AWS Simple Object Storage (S3) in response to a message you publish to SNS.
At the end of this lab, you will be able to:
- Create an SNS topic
- Create a Lambda function
- Configure SNS to trigger your Lambda function
- Publish a message in SNS
- Verify that Lambda processed your SNS message
This Lab is intended for:
