See how you can now use Amazon CloudFront to negotiate HTTPS connections to origins using Elliptic Curve Digital Signature Algorithm (ECDSA). ECDSA uses smaller keys that are faster, yet, just as secure, as the older RSA algorithm. The smaller keys will also increase the number of TLS handshakes that your origins can process per second, thereby saving compute cycles and reducing your cost of cryptography.

Do you have lots of images that need to be modified before delivery? No problem with Amazon CloudFront and Lambda@Edge. Read more on how you can use our services to modify image dimensions, apply watermarks, or optimize formats based on browser support all on the fly. Optimizing your image delivery can lead to a better experience for your users while also reducing your bandwidth usage.

Authorization, the function of specifying access rights to resources is often required to help protect restricted content in web applications. This post will show you how to implement a serverless authorization of viewers using Amazon CloudFront, Lambda@Edge and Amazon Cognito without modifying your origin resources.

Adding security response headers is often achievable by modifications to your application configuration. In this blog we will focus on how to achieve the same result when you have an application that can’t be modified at the origin (e.g., a web site hosted in Amazon S3).

Today Lambda@Edge announces a new feature that allows you to do content-based routing. Now you can programmatically define the origin based on logic in your Lambda function. This enables you to route requests to different origins based on request attributes such as headers, query strings, and cookies. Read our blog post to learn about different use cases and how you can set this up within your own architecture.
