In this blog post, we highlight how Elastic Network Adapter (ENA) Express can improve workload performance in conventional network applications, such as databases, file systems, and media encoding. We begin by demonstrating how ENA Express can significantly improve tail latency when used with in-memory databases. From there, we will explore the advantages it offers to […]

In an earlier post, we discussed how the hub-and-spoke architecture introduced by Local Zones unlocks more choices than ever for geographies where lower latency access can be introduced. Through workload placement techniques offered by service mesh technology for “east-west traffic”, inter-service communication within a customer’s Virtual Private Cloud (VPC), customers can make sure that microservice […]

AWS Transit Gateway is a network transit hub that enables you to connect thousands of Amazon Virtual Private Clouds (Amazon VPCs) and your on-premises networks using a single gateway. This simplifies your network connection and puts an end to complex peering relationships. AWS Transit Gateway Flow Logs enables you to export detailed telemetry information, such as source/destination […]

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 […]
