AWS Global Accelerator
#41 · Level 2 · Scaling and resilience · Scaling and trafficConcept
Section titled “Concept”AWS Global Accelerator takes users’ traffic to your app over AWS’s own global network. It gives your app two fixed (static) IP addresses, which are announced from many Edge Locations around the world at the same time. Users enter at a nearby Edge Location, then travel over the AWS network to the real endpoint. An endpoint can be an Application Load Balancer, a Network Load Balancer, an EC2 instance or an Elastic IP. It runs health checks and sends traffic only to healthy endpoints, but unlike CloudFront it does not cache content.
Simple example
Section titled “Simple example”Taking the expressway instead of the regular road with traffic jams — you get onto the fast road right at the nearest toll plaza.
Why it’s needed
Section titled “Why it’s needed”For users far away, an app can be slow and unstable. And if one Region goes down, traffic needs to be sent to another Region quickly.
Where it’s used
Section titled “Where it’s used”Online games, real-time apps, and a fixed address for apps running in several Regions.
