If your network architecture is complex, and you’d like to quickly identify application connectivity issues due to infrastructure changes, then the new Amazon Virtual Private Cloud (VPC) Reachability Analyzer can help. Often times, it is not always clear if changes to VPC infrastructure are affecting connectivity to applications and other AWS services. By implementing automated […]

AWS Global Accelerator is a network layer service that directs traffic to optimal endpoints over the AWS global network, this improves the availability and performance of your internet applications that are used by a global audience. It provides static IP addresses that act as a fixed entry point to your application endpoints in a single or multiple […]

If you have ever used Amazon Route 53 health checks to monitor resources, you know that monitored resources must have public IP addresses. This is because Route 53 health checkers are public and they can only monitor hosts with IP addresses that are publicly routable on the internet. You may want to monitor your resources […]

As promised in my previous post of this series about Lambda@Edge, in this new blog post I’m sharing some best practices for managing a Lambda@Edge application. So how do you roll out code or configuration changes to a Lambda@Edge function and Amazon CloudFront distribution in a safe and controlled way? Over time, as your application evolves, you’ll […]

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 […]

This post discusses the basics of setting up a simple serverless video on demand (VOD) workflow so you can experiment with streaming video with minimal configurations required. (If you have a more advanced VOD use case, check out this post and CloudFormation template from AWS Answers.) To setup a serveless video transcoding workflow, you first […]

Lambda@Edge provides you with the ability to bring compute power closer to client applications. With the recent increase in function limits and ability to send binary responses, as well as the addition of remote calling from functions, the capabilities of Lambda@Edge have grown. This post demonstrates how you can take an application with a relatively slow rate of changing data and use Lambda@Edge to both provide low latency data to application clients and remove unnecessary calls to a backend service.
