Centralized Ingress - Auto Scaling Group Target
Publication date: March 24, 2022 (Diagram history)
This architecture adds a Network Load Balancer with a static IP to eliminate the need for manual instance registration. The Application Load Balancer in the Central Ingress VPC targets the Network Load Balancer IP address through AWS Transit Gateway, and instances register automatically using an Auto Scaling group.
Centralized ingress with Auto Scaling group target architecture
The following steps describe the data flow in this architecture:
-
Traffic from the internet reaches the Central Ingress VPC. The Application Load Balancer sends the request to the target group using the Network Load Balancer static IP address through AWS Transit Gateway.
-
The traffic forwards to the Application VPC according to the Transit Gateway route table associated with the Central Ingress VPC.
-
The traffic enters the Application VPC and forwards to the Network Load Balancer IP address.
-
The Network Load Balancer forwards the traffic to registered instances in the Auto Scaling group using an instance ID target type.
