What is A Remote Procedure Call?

A remote procedure call (RPC) is an architectural style in API (application programming interface) design. It is used in building distributed client-server-based applications. Software developers use previously developed components (or third-party ones) to perform functions, so they do not have to rewrite the code every time.  

• To call remote functions in external servers as if they were their own 

• To add functionality by remotely calling these functions on other servers 

• To connect to other software or share functionality through integration
