Exploring new subnet management capabilities of Network Load Balancer
Introduction Today Amazon Web Services (AWS) is enhancing subnet management capabilities of Network Load Balancer (NLB). NLBs were previously restricted to only adding subnets in new Availability Zones (AZs), and they now support full subnet management, including removal of subnets, matching the capabilities of Application Load Balancer (ALB). This enhancement offers organizations greater control over […]

Load Balancer Migration to AWS: Recommended Strategies and Best Practices
In today’s world, organizations are increasingly looking to migrate their on-premises infrastructure to the cloud to take advantage of scalability, cost-effectiveness, and agility offered by cloud. One critical component of many enterprise architectures is the load balancer, which distributes incoming traffic across multiple servers. If you’re considering migrating your on-premise hardware load balancers to AWS, it’s […]
Using cross-zone load balancing with zonal shift
Today, we’re announcing Amazon Application Recovery Controller (ARC) zonal shift support for Application Load Balancers (ALB) with cross-zone load balancing enabled. This complements the support for Network Load Balancers (NLB) using cross-zone load balancing we announced previously. Now you can use zonal shift with both NLBs and ALBs, with or without cross-zone load balancing configured, […]
Building a global, low-latency NTP service with static IP addresses
As organizations continue to roll out cloud-connected Internet-of-Things (IoT) applications, the need for accurate and reliable time synchronization has become increasingly critical. Although Amazon Web Services (AWS) provides the Amazon Time Sync Service for basic Network Time Protocol (NTP) needs, some IoT scenarios need a custom NTP solution. For example, users want to serve many IoT […]

Introducing configurable TCP idle timeout for Gateway Load Balancer
Update: Sep 10, 2024 – Corrected a CloudWatch metric name. Amazon Web Service (AWS) Gateway Load Balancer (GWLB) is a managed AWS service that allows you to insert third-party firewall appliances into the data path. GWLB helps you deploy, scale, and manage third-party appliances, and it acts as a bump-in-the-wire device and passes traffic transparently […]
Security best practices when using ALB authentication
At AWS, security is the top priority, and we are committed to providing you with the necessary guidance to fortify the security posture of your environment. In 2018, we introduced built-in authentication support for Application Load Balancers (ALBs), enabling secure user authentication as they access applications. This feature allows developers to offload the authentication responsibility […]
Preserving client IP address with Proxy protocol v2 and Network Load Balancer
When a load balancer or proxy cannot preserve the client’s original IP address, it may rewrite the IP address or use its own IP address for routing purposes. In this scenario, common practices such as inserting the original IP address into the request headers (for example, X-Forwarded-For) or utilizing Proxy protocol are widely used to […]
Introducing dual-stack without public IPv4 Application Load Balancer
In May 2024, Amazon Web Services (AWS) launched a new feature for internet-facing Application Load Balancers. This enhancement allows you to provision an internet-facing Application Load Balancer without needing public IPv4 addresses, enabling clients to connect using only IPv6 addresses. To connect, clients resolve the AAAA DNS records assigned to the Application Load Balancer. The […]
