[GCP]HTTP(S) Load Balancing

HTTP(S) 에 대한 global Load Balancer 이다.

 

1. forwarding rule 은 다이렉트로 request 를 target proxy 로 전달한다.

2. target proxy 는 url map 을 통해서 적절한 backend service 로 라우팅 해준다.

3. backend service 는 request 를 서버 용량, 상태에 따라서 적절한 backend instance 로 전달한다. 각각의 backend instance는 health check 를 사용한다.
