AWS WAF offers advanced features for filtering undesired web application traffic, such as Bot Control and Fraud Control. These intelligent threat mitigations include techniques such as client-side interrogations using JavaScript challenges or CAPTCHA, as well as client-side behavioral analysis. Implementing these techniques on a web page with a same-origin access is simple. When a cross-domain […]

You can now add AWS WAF protections to Amazon CloudFront distributions with one click. In this walkthrough, we will guide you through setting up and monitoring protections offered by this new feature along with pricing and additional security recommendations. This blog relates to Amazon CloudFront — a AWS service that you can use to deliver […]

Blue/green deployment is a widely used deployment technique in software development aimed at minimizing downtime and risks associated with introducing new code. The strategy involves concurrently running two identical environments, namely blue and green, and directing traffic between them as necessary. This allows you to have uninterrupted delivery of new features and updates, with no […]

Many of our customers use Amazon CloudFront and Amazon Simple Storage Service (Amazon S3) to deploy Single Page Applications (SPA): web applications created with React, Angular, Vue, etc. The development teams of these SPAs often have the following, seemingly conflicting, requirements: Users should experience as little latency as possible in downloading the web application. Therefore, […]

Whether you’re serving dynamic content from an Amazon Elastic Load Balancer (Amazon ELB), Amazon Elastic Compute Cloud (Amazon EC2) instances, Amazon API Gateway, or AWS Lambda to the end users on the Internet, you can improve the performance and security, and optimize the cost of your content delivery by using Amazon CloudFront as your content delivery network (CDN). […]

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 […]

This post provides a solution to enhance the Amazon CloudFront origin security of on-premises web servers by automating the AWS IP prefix update process for some network firewalls. CloudFront is a content delivery network (CDN) service that securely delivers data, videos, applications, and APIs to customers globally with low latency and high transfer speeds—all within […]

Earlier this year, we released technical guidance regarding three advanced design patterns for highly available applications using Amazon CloudFront and Amazon Route 53. In this post, we dive deeper into CloudFront origin failover, Amazon Route 53 DNS failover, and the hybrid origin failover approach to further enhance the availability of your web applications. We also […]

Organizations require methods to restrict access to content to adhere to compliance and regulatory requirements, sanctions, privacy laws, territorial ownership rights, security controls, etc. One way that companies restrict access is by Geo-blocking – restricting access to a website or another piece of content based on a user’s location. A popular method of geo-blocking content is […]

While maintaining a web application, sometimes we need to build a simple logic that must  run in low latency. For example, you may want to set up website redirection based on condition, or quickly verify an incoming header. CloudFront Functions is ideal for these use cases since it lets you write lightweight JavaScript code that […]
