Global Accelerator ¶
AWS Global Accelerator is a service that allows you to route traffic to your applications using the AWS global network instead of the internet. The internet can be congested and AWS claim that by using their private network infrastructure you can improve the connection speed and performance by as much as 60%.
Global Accelerator provides two global static public IPs that act as a fixed entry point to your application endpoints, such as Application Load Balancers, Network Load Balancers, Amazon Elastic Compute Cloud (EC2) instances, and elastic IPs.
GA then optimises the path from those IP addresses to your application which results in lower latency and better network performance.
Why use GA?
Whether your users are distributed locally or across the globe, you are always going to want them to connect to your application using the fastest reliable connection with the lowest latency which is something the public internet may not be able to provide consistently.
Because GA can detect unhealthy endpoints and swap traffic to a healthy option within 30 seconds, it provides a seamless method of ensuring you have the fastest method of delivering traffic to your application endpoints and resolving issues as they occur.
