Target Group Load Shedding for Application Load Balancer

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-type Target Group for Network Load Balancer

(April 25, 2024) Clarification – AWS PrivateLink does not currently support UDP.   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, […]

Building an Open Source IDS IPS service for Gateway Load Balancer

The Gateway Load Balancer (GWLB) service launched with support from the partner network. These partners provide networking appliances that enable customers to perform varying levels of packet inspection on flows that pass through them, taking action as necessary and as defined within their configuration. For a list of partners that support GWLB, refer to the […]

Scale traffic using multiple Interface Endpoints

Update: As of January 27, 2022, AWS PrivateLink publishes data points to Amazon CloudWatch for your interface endpoints, Gateway Load Balancer endpoints, and endpoint services. CloudWatch enables you to retrieve statistics about those data points as an ordered set of time series data, known as metrics. As a PrivateLink Endpoint owner, you can use metrics […]

Using AWS Lambda to enable static IP addresses for Application Load Balancers

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 […]

Resolve DNS names of Network Load Balancer nodes to limit cross-Zone traffic

Introduction Network Load Balancer (NLB), part of the Elastic Load Balancing Family, is the flagship Layer 4 load balancer for AWS. It offers elastic capacity, high performance, and integration with many other AWS services (such as Amazon EC2 Auto Scaling). NLB is designed to handle millions of requests per second while maintaining ultra-low latency, improving […]

Best practices for deploying Gateway Load Balancer

Updated 03/04/2023: The following updates were made to this blog: Expanded the behavior of idle timeout to address TCP flow and UDP packets. Referenced price reduction announcement for inter-az charges Referenced enhancement made in target failover of the existing flows in GWLB Introduction At re:Invent 2020, we launched Gateway Load Balancer (GWLB), a service that […]

Accessing an AWS API Gateway via static IP addresses provided by AWS Global Accelerator

Introduction In this article, I will walk you through the steps to configure Amazon API Gateway in combination with AWS Global Accelerator to present Internet-facing API via static IP addresses to end users. This design addresses the need for static IP safelisting and also provides additional performance benefits to end users by sending user’s traffic […]

Solving DNS zone apex challenges with third-party DNS providers using AWS

Many customers ask us how they can point their zone apex to their web content if it uses a DNS name rather than an IP address. This blog covers three design patterns and approaches that solve zone apex challenges with third-party DNS providers for applications hosted in AWS—and the pros and cons of each approach.

Configuring an Application Load Balancer on AWS Outposts

Introduction AWS Outposts bring AWS infrastructure and services to virtually any datacenter, co-location space, or on-premises facility, in the form of a physical rack connected to the AWS global network. AWS services run locally on the Outpost, and you can access the full range of AWS services available in your Region—including Application Load Balancer (ALB). […]
