💡 Proxy

A proxy is a software that makes requests on behalf of a client.

• Any requests that the client makes has to pass through the proxy.The api proxy sets an abstraction between the consumers and the server and decouples them.
• All connections are established between the client and the proxy.So the services dont have to be aware of each other or interact with each other.
• It can decouple the consumers from the backend service and vice-versa.
• The server is not aware of the clients information.
• The client is aware of the final destination.

💡 REVERSE Proxy

• In the proxy configuration , the server doesn't know the client.
• In the reverse proxy configuration , the client doesn't know the server.

Eg- When we have multiple servers , the proxy communicates the request to one of the servers . This is one of the most common use cases for a reverse proxy : Load Balancing (eg - NGINX server)
