Load balancer vs Gateway vs reverse proxy vs forward proxy

Today I will discuss about most use service in system design and difference between them.

load balancer distribute load to different server according to algorithim set in load balancer configuration.

• Gateway have additional + load balancer.

• it can process the request and send response + distribute load to different server according to alogrithim set in load balancer configuration.

• above I have discuss about two scenario.

forward proxy is used to hide the user identity. it make a request to server on behave of client.

reverce proxy is used to hide the server identity. it make a response to client on behave of server.

simple request response using all the services in one system.
