Before you head into the Thanksgiving holiday, take a moment to read through this guide and start planning your AWS Networking re:Invent journey! From December 1st to December 5th, Las Vegas, Nevada will transform into the ultimate destination for cloud innovation, making it the perfect time to look ahead to the one of the most […]

AWS Application Load Balancer is an HTTP request load balancer designed to provide scalability through load distribution and high availability through target health detection and unhealthy target isolation. Today, we are excited to introduce ALB Target Optimizer, a powerful new feature through which ALB delivers optimal concurrency to each target. In this post, we will […]

Today Amazon Web Services (AWS) is launching weighted target groups for Network Load Balancers (NLB). This feature allows users to configure static weights among multiple NLB target groups. Weighted target groups enable you to easily perform blue/green or canary deployment strategies with zero downtime and without the need of multiple load balancers. This feature is […]

Today, AWS announces the launch of QUIC protocol support for Network Load Balancer (NLB). This capability enables customers to forward QUIC traffic to their targets with ultra-low latency while maintaining session stickiness using QUIC Connection IDs. In this blog we will provide an overview of QUIC, demonstrate how to enable it using the AWS Console […]

In November 2024, Amazon CloudFront introduced CloudFront Virtual Private Cloud (VPC) origins, a security feature that allowed customers to deliver content from applications hosted in private subnets. In addition, we are now introducing cross-account support for Amazon CloudFront VPC origins, enabling network traffic flow between Amazon CloudFront and Application Load Balancers (ALBs), Network Load Balancers […]

Today we’re announcing the general availability of rewriting URLs and host headers natively on Amazon Web Services (AWS) Application Load Balancers (ALB). You can use this new feature to implement regex matches based on request parameters and rewrite both host headers and URLs before routing to your targets. Operating at Layer 7 (application layer) of […]

This three-part series explores design patterns and strategies to enhance application resiliency through multi-cluster deployment on Amazon Elastic Kubernetes Service (EKS). In this first part, we address a common challenge when using a Network Load Balancer (NLB) in multi-cluster environments. Organizations increasingly rely on Kubernetes—whether through Amazon Elastic Kubernetes Service (EKS) or self-managed clusters on […]

As organizations increasingly adopt IPv6 to address public IPv4 exhaustion, private IPv4 scarcity—especially in large-scale networks—and the need to support IPv6-only clients, securing both IPv4 and IPv6 traffic becomes critical. We can apply consistent traffic inspection for inbound and outbound flows in Amazon Virtual Private Clouds (Amazon VPCs) to maintain security. In this post, we […]

Application Load Balancer (ALB) operates at layer-7 of the OSI model and allows you to load balance HTTP and HTTPS requests to its backend targets. In March 2025, we launched ALB and Amazon VPC IP Address Manager (IPAM) integration that allows you to use predictable IP address blocks for your internet-facing ALBs. This feature helps […]

In this post, we explore how Amazon Elastic Compute Cloud (Amazon EC2) data transfer costs apply to the communication between Network Load Balancer (NLB), clients, and targets in multiple scenarios, to help you optimize data transfer costs on Amazon Web Services (AWS). For Classic and Application load balancers, visit our post, Exploring Data Transfer Costs […]
