In part one of this post, we introduced two methods, Amazon CloudFront Functions and Lambda@Edge, for executing custom code at CloudFront edge Locations to modify request origins dynamically. This second post provides step-by-step setup instructions and code samples for implementing the two approaches for a subscription-based routing use case: CloudFront Functions with query string parameters […]

In the modern digital landscape, our lives are inescapably dominated by screens and browsers. From global product launches to flash sales and virtual concerts, events that once drew crowds to physical venues now drive millions of users to digital platforms simultaneously. The rapid rise of digital-first experiences has made the need to dynamically adjust content […]

Cross-origin resource sharing (CORS) is a security feature implemented by web browsers that controls which web pages or web applications are allowed to make requests to a different domain or origin. In other words, CORS is a mechanism that prevents a web page hosted on one domain from making requests for resources from a different […]

[Update on May 7th 2025] Amazon CloudFront SaaS Manager introduces a new type of distribution called a multi-tenant distribution. A key challenge for SaaS providers is designing secure, scalable tenant routing mechanisms to identify tenants and route requests to appropriate resources. Effective tenant routing ensures isolation, scalability, and security. This post explores strategies for routing […]

In this post, we demonstrate how to implement tag-based invalidation in Amazon CloudFront with Lambda@Edge, Amazon DynamoDB, AWS Lambda, and AWS Step Functions. This post provides you with a reference architecture and sample code artifacts to help you deploy and test tag-based invalidation. Let’s look at some use cases where tagging pages together might be […]

As organizations grow, they must often serve geographically dispersed users with low latency, prompting them to have a distributed global infrastructure in the cloud. In this article, we describe how to deploy global API endpoints to reduce latency for end-users while increasing an application’s availability. By using the AWS Global Network and Amazon CloudFront to deploy applications into multiple […]

In this post, you’ll learn about the ‘multi-function packager’ framework that handles the assembly and execution of discrete Edge functions. Amazon CloudFront is a content delivery network (CDN) service that improves the performance, availability, and security of your application, allowing you to serve a consistent experience to your viewers globally. Lambda@Edge and CloudFront Functions are the […]

Search engine crawlers – a special bot type used to index your site – are very important visitors. They make sure that your content is searchable by end users. If a crawler can’t easily read your content, then any updates you make might not be immediately reflected in the search results. Depending on the algorithms […]

In today’s digital-first business environment with a globally distributed customer base, it becomes important to adopt an architecture that helps customers deliver digital assets to end-users with the lowest possible latency based on the geo-proximity of assets to the end user. Companies with digital assets stored in Amazon Simple Storage Service (Amazon S3) commonly configure the traffic to be […]

Any web application using Amazon CloudFront benefits from the inherent high availability of this AWS service. It’s a globally distributed network that is immune to local hardware failures or network congestion. Furthermore, it’s built on top of the AWS global network, which provides better isolation from the public internet. Finally, it’s designed with various advanced […]
