What Is a Remote Procedure Call (RPC)?

Standing prominent among the many network processes is the concept known as ‘Remote Procedure Call,’ often shortened to RPC. This blog post is dedicated to offering a comprehensive understanding of RPC, its underlying mechanism, and its significance in the realm of Information Technology.

What is a Remote Procedure Call?

A Remote Procedure Call is essentially a protocol that allows a program on one computer to execute a code on a different machine without the programmer needing to explicitly code for this interaction. In other words, it is akin to calling a function or a method available in a different system, hence the name ‘remote procedure call.’

A salient feature of RPC is its ability to mask the intricacies of network interfaces, which lets developers focus on the functionality of their application without delving into the complexities of network protocols.

How does a Remote Procedure Call Work?

The functioning of a Remote Procedure Call can be broken down into a series of steps:

  1. Procedure invocation: The client machine initiates the process by invoking a procedure on the server machine. This invocation contains the procedure’s parameters, which are passed by the client.
  2. Message transmission: Following the procedure invocation, the client sends a message to the server via the network. This message includes the procedure’s identifier along with its parameters.
  3. Procedure execution: Upon receiving the message, the server executes the procedure using the provided parameters.
  4. Result transmission: Once the procedure’s execution is complete, the server sends the result back to the client machine.
  5. Result reception: Finally, the client receives the result and the procedure invocation resumes as if the called procedure was a local procedure.

Importance of Remote Procedure Calls

Remote Procedure Calls hold paramount importance in the field of distributed computing and web services. They allow for seamless communication between different software systems located on separate machines. This facilitates the sharing and processing of data across various systems, thereby enhancing the functionality and efficiency of these systems.

In addition, RPCs play a significant role in service-oriented architectures and microservices. They enable these systems to work together as a single entity by allowing the individual services to communicate with each other.


Remote Procedure Calls serve as an integral component in network computing, bridging the gap between different systems and facilitating seamless data exchange and processing. By masking the complexities of network interfaces, they allow developers to concentrate on the core functionality of their applications, thereby contributing to efficient and effective software development.
