Application Load Balancer
An Application Load Balancer works at the application layer and supports HTTP/HTTPS routing features such as host- and path-based routing.
Why it matters
It is useful for modern web applications and APIs that need application-aware routing.
How it works
Listener → rules → target group → healthy target.
Core Concept
ALB supports listener rules and path/host-based routing.
Example: /api traffic can route to an API target group while /app traffic routes to a frontend target group.
