Centralized Ingress - Amazon EC2 Target
Publication date: March 24, 2022 (Diagram history)
This architecture uses a centralized ingress Amazon VPC with a public Application Load Balancer and IP targets. You directly target the IP addresses of Amazon EC2 instances in the application VPC through AWS Transit Gateway. This approach requires manual management of IP registrations on the ALB.
Centralized ingress with Amazon EC2 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 with the configured 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 Amazon EC2 instance.
For more information about Application Load Balancer target group types, see Target groups for your Application Load Balancers.
