This construct registers targets, such as EC2 instances, ECS tasks, or Lambda functions, with a load balancer’s target group. A target group routes requests from the load balancer to the registered targets based on health checks and other configured settings. For instance, web servers can be registered to a target group, allowing a load balancer to distribute incoming web traffic across the healthy servers.
Registering targets is fundamental to load balancing functionality. It enables the distribution of traffic, improves availability and fault tolerance, and allows for scaling resources based on demand. Historically, load balancing required manual configuration and management. The ability to programmatically manage target registration simplifies infrastructure automation and enables dynamic scaling, a cornerstone of modern cloud architectures.
