Networking & Content Delivery

Introduction Lambda@Edge is a feature of Amazon CloudFront that allows developers to implement custom logic for manipulating HTTP request/response exchanges or generating responses on the fly with low latency. Lambda@Edge empowers our customers with a full programming language (Node.js) to implement advanced logic. Learn more at edge networking with AWS. While customers often write stateless […]

Introduction Werner Vogels, chief technology officer for AWS, has been quoted as saying: “Everything fails all the time.” Well, his quote applies as well to content delivery with Amazon CloudFront and Lambda@Edge. In content delivery, issues might occur in different places, for example: On your origin, when it returns HTTP 5xx errors On CloudFront, when […]

A successful hybrid networking strategy goes beyond private network connectivity. It often requires dealing with independent internal zones both in Amazon Virtual Private Cloud (Amazon VPC) and on-premises. Such a strategy needs Domain Name System (DNS) naming that spans the entire network. Typically, this is managed by providing name resolution services in the same place […]

Amazon Virtual Private Cloud (Amazon VPC) provides you with the ability to create as many virtual networks as you need. It also provides different options for connecting these networks to each other and to non-AWS infrastructure, such as on-premises data centers, remote headquarters, or other offices. Most of you start this journey with a few […]

Last year, a colleague of mine wrote a blog post about new security measures that Amazon CloudFront was implementing to enhance the security of how domains are used on CloudFront distributions. This included mitigations to prevent the abusive use of domain fronting practices by not allowing SSL handshake requests and subsequent requests over the secured […]

Many websites and web applications serve a combination of static content—HTML, CSS, JPG, or other files that all end viewers can see—and dynamic content, which is personalized for each end viewer. Fortunately, Amazon CloudFront can serve both types of content, to reduce latency, protect your architecture, and optimize costs. In this post, we demonstrate how […]

As customers  migrate a growing number of critical workloads to AWS, they have requested more capabilities when they deploy applications across multiple Regions.  Critical workloads, such as dynamic API delivery, gaming, and video/voice over IP require higher levels of availability and performance through the use of multi-Region architectures.  This demand brings several challenges you must consider, from planning […]

Resources in AWS rely heavily on their underlying network to deliver a service at optimal performance. For example, your databases could be fine-tuned and your front end application servers could be running on the most expensive, high-end Amazon EC2 instances available. However, if the underlying network is experiencing an issue, all of these beneficial factors […]

Just as with AWS Lambda, Lambda@Edge supports logging to CloudWatch, which can help you to troubleshoot your Lambda function code or to log custom data that is not available in CloudFront access logs.  Lambda@Edge functions are replicated around the world so CloudFront can invoke them closer to your end viewers, and CloudWatch log files for […]
