Process Amazon SNS Notifications with AWS Lambda

Takes 60 mins

AWS Lambda services work to deploy and manage applications without the hassle of managing and maintaining the underlying resources. AWS Lambda functions can also be used to process Amazon Simple Notification Service (Amazon SNS) notifications.

Amazon Simple Notification Service (SNS) is a well-constructed service that processes messages using a publish/subscribe model. Amazon SNS supports Lambda functions as a target for messages sent to a topic. You can subscribe your Lambda function to topics to receive notifications.
