All You Need To Know About The New AWS Gateway Load Balancer


As businesses and organizations continue to expand their online presence, the need for scalable and highly available architectures becomes even more important. One of the tools Amazon Web Services (AWS) provides to accomplish this is the Gateway Load Balancer (GWLB). In this article, we’ll look at what GWLB is, how it works, and some of its key benefits.

What is AWS Gateway Load Balancer?

Like other AWS load balancers, AWS Gateway load balancer is a highly available and scalable network services that help distribute incoming traffic across multiple resources such as EC2 instances, containers, IP addresses, and more. It provides a single entry point for traffic into your network and automatically adjusts to handle increasing traffic volumes. GWLB is also a regional service and can span multiple Availability Zones within a region.

How to use?

AWS Gateway LB acts as a layer 3 load balancer. This means that it works at the network level of the OSI model. This also allows you to distribute traffic across your resources based on IP address and port, and even perform health checks on those resources to ensure they are available and responsive. increase.

It’s designed to handle traffic sent over the internet or an Amazon Virtual Private Cloud (VPC) connection. You can receive traffic from various sources such as Amazon Route 53 DNS records, AWS Global Accelerator, or directly from the Internet.

Gateway LB distributes traffic across resources using a combination of algorithms such as Round Robin, Most Outstanding Requests, and Weighted IP. It also supports routing based on TCP/UDP protocols and can perform SSL/TLS termination that can offload processing of encrypted traffic.

Benefits of AWS Gateway Load Balancer?

AWS Gateway LB can handle large amounts of traffic and automatically scales to meet growing demand. It can handle millions of requests per second. It can also be used to load balance both Internet-based and internal applications.

High availability:
It is also designed for high availability and has automatic failover capabilities. It can as well detect when resources become unavailable and route traffic to healthy resources.

You can also terminate SSL/TLS connections and offload processing of encrypted traffic. This reduces resource load and improves performance.

Cost efficient:
A very cost effective solution for traffic load balancing. AWS also offer a pay-as-you-go pricing model. In other words, you only pay for the resources you use.


AWS Gateway Load Balancer is a powerful tool for handling high volumes of traffic and distributing traffic across multiple resources. It also provides a highly available and scalable solution for businesses and organizations that require a robust and reliable architecture. In addition, Gateway Load Balancer helps improve performance and reduce costs with its ability to handle millions of requests per second and support for SSL/TLS termination.
