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 […]

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, […]

[Update on May 7th 2025] Amazon CloudFront SaaS Manager introduces a new type of distribution called a multi-tenant distribution. A key challenge for SaaS providers is designing secure, scalable tenant routing mechanisms to identify tenants and route requests to appropriate resources. Effective tenant routing ensures isolation, scalability, and security. This post explores strategies for routing […]

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 Customers use multi-region architecture to achieve application resiliency such as Active-Active or Disaster Recovery (DR). Depending on DR strategy, customers may need to have failover from one region to the next. DR strategies are covered off in detail in a prior AWS Blog. DR strategies include either an Active/Passive or Multi-Site Active/Active approaches. Active/Passive […]

Update – 3rd May 2023 With this update, zonal shift for Amazon Route 53 Application Recovery Controller is now also available in the following AWS Regions. Learn more in the updated What’s New post or zonal shift documentation. Today we’re introducing zonal shift, a new capability of Amazon Route 53 Application Recovery Controller (Route 53 […]

Introduction: AWS Gateway Load Balancer (GWLB) is an Elastic Load Balancing (ELB) service that allows customers to insert third-party virtual appliances such as firewall, intrusion detection and prevention systems (IDS/IPS), network observability and others, transparently into the traffic path. Application Load Balancer (ALB) and Network Load Balancer (NLB) are reverse proxies and traffic is routed […]

Load Shedding Load shedding is the practice of sacrificing enough application traffic to keep partial availability in the presence of an overload condition. Used in conjunction with strategies like load balancing, load shedding helps applications support service level agreements (SLAs) when increased traffic overwhelms available system resources. While the cloud’s elasticity reduces the need for […]

Application Load Balancer (ALB) is a fully managed layer 7 load balancing service that load balances incoming traffic across multiple targets, such as Amazon EC2 instances. ALB supports advanced request routing features based on parameters like HTTP headers and methods, query string, host and path based routing. ALB also offloads important capabilities including TLS termination, […]

Update: On September 27th, 2021, we launched Application Load Balancer(ALB)-type target groups for Network Load Balancer (NLB). With this launch, you can register ALB as a target of NLB to forward traffic from NLB to ALB without needing to actively manage ALB IP address changes through Lambda. You can also use AWS Global Accelerator to […]
