Customers use AWS Network Load Balancer (NLB), Classic Load Balancer (CLB), or Application Load Balancer (ALB) as load balancers or ingress with Amazon Elastic Kubernetes Service (Amazon EKS) clusters. AWS Load Balancer Controller is designed to help manage Elastic Load Balancers for a Kubernetes cluster. It satisfies Kubernetes Ingress resources by provisioning ALBs and Kubernetes […]

Amazon Virtual Private Cloud (VPC) endpoints – powered by AWS PrivateLink—allow you to securely expose your application to consumers on AWS without using public IP space and without worrying about overlapping private IP space. You also don’t have to worry about creating bidirectional network paths using services like AWS Transit Gateway or Amazon VPC Peering.To […]

This blog post explores how Amazon Q, the generative artificial intelligence (AI) powered assistant from AWS, helps you troubleshoot network-related issues by working with Amazon VPC Reachability Analyzer. These are exciting times for cloud networking! We’re a long way from the days of debugging connectivity issues with ping and traceroute. Now we ask questions in […]

Introduction Since their introduction in 2010, tags have been helping Amazon Web Services (AWS) customers identify, organize, and manage their resources by adding referenceable key/value pairs. In this post, we explore how tags can be used to automate the addition and removal of Amazon VPC Lattice resource associations, and cross account resource shares using Amazon […]

In this blog, we explore Automatic Target Weights (ATW), which can reduce the number of errors users experience when using web applications. ATW provides the ability to detect and mitigate gray failures for targets behind Application Load Balancers (ALB). A gray failure occurs when an ALB target passes active load balancer health checks, making it look healthy, but still returns errors. This scenario could be caused by many things, including application bugs, a dependency failure, intermittent network packet loss, a cold cache on a newly launched target, CPU overload, and more.

Introduction In this post, we explain how Amazon EC2 interprets idle timeouts and how to customize this configuration to optimize for your traffic patterns and workloads. We also dive into some common use-cases. Earlier this year, Amazon Elastic Compute Cloud (Amazon EC2) announced the Conntrack Utilization Metric for EC2 instances that offers you the ability […]

This blog post describes how to implement cross-account sharing for Amazon Route 53 Application Recovery Controller (Route 53 ARC), by using AWS Resource Access Manager (AWS RAM). The post walks through setting up a resource share, highlights the benefits of cross-account sharing, and reviews the factors to consider when you set up resource sharing in […]

As security threats have become more sophisticated and easier to scale, customers increasingly use Amazon CloudFront and AWS WAF together to improve the performance, resiliency, and security of their web applications and APIs. CloudFront is a Content Delivery Network (CDN) that reduces latency by delivering data to viewers anywhere in the world using one of […]

In this post, we explore how Amazon Elastic Compute Cloud (Amazon EC2) data transfer costs apply to the communication between Classic Load Balancers (CLB), Application Load Balancer (ALB), clients, and targets in multiple scenarios, to help you optimize data transfer costs on AWS. Elastic Load Balancing offers four types of load balancers, all featuring high […]

AWS Global Accelerator now offers support for routing IPv6 traffic directly to dual-stack Network Load Balancer (NLB) endpoints. With this support, you can use dual-stack NLB endpoints behind dual-stack accelerators to achieve end-to-end IPv6 connectivity. In this post, we describe how you can set up a dual-stack accelerator with NLB endpoints, and review considerations for […]
