Path-Based Routing with Application Load Balancer (AWS ALB): Efficiently Directing Traffic Based on URL Paths

2024-08-11T13:05:16+00:00

An Application Load Balancer enables you to set up a listener with rules that direct incoming requests to target groups based on the URL. This capability is unique to Application Load Balancers and is not offered by other load balancer types like Classic Load Balancer, Network Load Balancer, and Gateway Load Balancer. The path pattern rules only apply to the path of the URL and do not consider the URL's query parameters. Path-based routing allows you to host multiple microservices behind a single ALB, directing traffic to the appropriate service based on the requested path. Important Purposes of Path-based Routing [...]
