FAQ

Q: What is it?


A: This solution provides a collection of Lambda@Edge applications, helping you easily use CloudFront. 

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 provides commonly used Lambda@Edge functions for various scenarios, allowing you can directly deploy them in the console or use them as code samples.

Q: What are the user scenarios?

A: Various CloudFront use cases, including:
  • Authentication, e.g. authenticate with Amazon Cognito, add security headers into request headers.
  • Validation, e.g. perform MD5 checksum and determine when return to the origin.
  • URL Rewrite, e.g. rewrite URL according to the cookie information.
  • URL Redirect, e.g. return related content according to the device type.
  • Override Request, e.g. modify the response status code.
  • Override Response, e.g. standardize the query.
  • Origin Selection, e.g. forward request to the nearest CDN PoP according to the current geolocation.
  • Personalize Content, e.g. resize images.
  • Security,  e.g. hotlinking protection.
Please find more details in the roadmap for this solution in Github.

Q: Who should use it?

A: Users who need to use CloudFront and need to expand its functions.

Q: What customer experience is like?

A: You can search through Amazon Web Services Serverless Application Repository (SAR) and find the desired Lambda@Edge applications generated through this solution, and directly deploy it into your account from SAR.
If you are not able to find Lambda@Edge that fits your use case, you can also refer to the GitHub source code in this solution to write your own Lambda@Edge code.

Q: How much does it cost?

A: The solution is free and you will be charged based on the actual usage of Amazon Web Services resources. 

Q: How do I get started with it?

A: In the Amazon Web Services Serverless Application Repository (SAR), you can see find all the Lambda@Edge applications released by the solution via two steps: 1. Check box "Show apps that create custom IAM roles or resource policies". 2. Search keyword "aws-cloudfront-extensions".

In SAR, you can "1-click" deploy your desired Lambda@Edge application into your Amazon Web Services account. After the deployment, you can easily setup CloudFront to work with the deployed Lambda@Edge. Please see the deployment guide for more details.

Q: How much development effort needed to use it?


A: The Lambda@Edge can be used after being deployed without extra development effort. If the out-of-box Lambda@Edge functions in the solution do not meet your specific scenarios or business needs, you can rewrite or customize the Lambda@Edge code.

Q: Can I deploy the solution in any Amazon Web Services Region?


A: This solution currently only supports deployment in Amazon Web Services Global Regions. It does not support China Regions.
