EndpointGroup

Source: src/AWS/GlobalAccelerator/EndpointGroup.ts

A Global Accelerator endpoint group — the set of regional endpoints (ALBs, NLBs, EC2 instances, or Elastic IPs) that a listener routes traffic to in one AWS Region, with traffic-dial and health-check configuration.

One endpoint group per region per listener. Everything except the listener and region is updatable in place.

Creating Endpoint Groups

Route to an Application Load Balancer

const group = yield* GlobalAccelerator.EndpointGroup("UsWest2", {
  listenerArn: listener.listenerArn,
  endpointGroupRegion: "us-west-2",
  endpoints: [{ endpointId: alb.loadBalancerArn }],
});

Weighted Endpoints with HTTP Health Checks

const group = yield* GlobalAccelerator.EndpointGroup("UsEast1", {
  listenerArn: listener.listenerArn,
  endpointGroupRegion: "us-east-1",
  endpoints: [
    { endpointId: blueAlb.loadBalancerArn, weight: 200 },
    { endpointId: greenAlb.loadBalancerArn, weight: 55 },
  ],
  healthCheckProtocol: "HTTP",
  healthCheckPath: "/health",
  healthCheckInterval: "10 seconds",
});

Traffic Management

const group = yield* GlobalAccelerator.EndpointGroup("Canary", {
  listenerArn: listener.listenerArn,
  endpointGroupRegion: "eu-west-1",
  trafficDialPercentage: 10,
});
