Endpoints for standard accelerators in AWS Global Accelerator

Endpoints for standard accelerators in AWS Global Accelerator can be Network Load Balancers, Application Load Balancers, Amazon EC2 instances, or Elastic IP addresses. In AWS Global Accelerator, static IP addresses serve as a single point of contact for clients, and, with a standard accelerator, Global Accelerator distributes incoming traffic across healthy endpoints. Global Accelerator directs traffic to endpoints by using the port (or port range) that you specify for the listener that the endpoint group for the endpoint belongs to.

Each endpoint group can have multiple endpoints. You can add each endpoint to multiple endpoint groups, but the endpoint groups must be associated with different listeners. A resource must be valid and active when you add it as an endpoint.

Important

Accelerators that you configure as dual-stack (that is, accelerators that you want to support IPv4 and IPv6) require that you add only endpoints that also support dual-stack. Network Load Balancers, Application Load Balancers, and Amazon EC2 instances can be added as dual-stack endpoints.

Global Accelerator continually monitors the health of all endpoints that are included in a standard endpoint group. It routes traffic only to the active endpoints that are healthy. If Global Accelerator doesn’t have any healthy endpoints to route traffic to, it routes traffic to all endpoints in the AWS Region.
