Target Groups

Create and manage AWS Target Groups to control application traffic routing

Target Groups route traffic from a Load Balancer to specific backend resources, such as EC2 instances, IP addresses, or other Load Balancers (ALBs). They allow fine-grained control over request routing and health checks.

Prerequisites

Before creating a Target Group, ensure the necessary resources are created and available. The types of targets you can register include EC2 Instances, ALBs (Application Load Balancers), and IP addresses.

You can find detailed instructions for creating these resources in the DuploCloud documentation:

• EC2 Instances

• ALBs (Application Load Balancers)

• IP Addresses: DuploCloud allows the use of IP addresses assigned to EC2 instances or other resources. Ensure the required IP addresses are available.

1. From the DuploCloud Portal, navigate to Cloud Services -> Networking -> Load Balancers.
