What does this Amazon Web Services Solution do?
Lambda@Edge is a feature of Amazon CloudFront that lets you run code closer to users of your application, which improves performance and reduces latency. With Lambda@Edge, you don't have to provision or manage infrastructure in multiple locations around the world. You pay only for the compute time you consume - there is no charge when your code is not running.
This solution offers a collection of Lambda@Edge applications, covering most common Lambda@Edge user scenarios. All the Lambda@Edge applications in this solution can be directly deployed into Amazon Web Services console.
The Lambda@Edge collection is part of "CloudFront-Extentions" GitHub project. Anyone in the open source community is welcomed to contribute to the project.

Solution Architecture and Description
All the Lambda@Edge applications in this solution are published publicly on Amazon Web Services Serverless Application Repository (SAR).
SAR is a managed repository for serverless applications. In the repository, you can find and deploy the pre-built Lambda@Edge applications released through this solution.
To find the Lambda@Edge applications, it takes two steps: 1. Check box "Show apps that create custom IAM roles or resource policies". 2. Search keywords the "aws-cloudfront-extensions".
In the application detail page, you can "1-click" deploy your desired Lambda@Edge application into your Amazon Web Services account. After the deployment, you just need to complete a simple setup, for example, setting CloudFront Trigger, to use the Lambda@Edge function. Please see the deployment guide for more details.
