As of today, Application Load Balancers (ALBs) now support AWS Lambda functions as targets. Build websites and web applications as serverless code, using AWS Lambda to manage and run your functions, and then configure an ALB to provide a simple HTTP/S frontend for requests coming from web browsers and clients. Triggering a Lambda Function from […]

For online retailers, the annual holiday season, special sales and new product launches are all exciting events that typically drive a rapid increase in site traffic. With Amazon CloudFront and Lambda@Edge, you can now build a Flash Crowd Management workflow that lets you control what proportion of incoming shopper traffic is allowed to access your backend application, while directing the remaining shoppers to a temporary waiting room- an alternate site where you can provide them a branded experience while they await their turn to access the application.

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.
