RPC vs. RMI: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on February 8, 2024
RPC (Remote Procedure Call) is a protocol that allows a program to execute a procedure on another computer, while RMI (Remote Method Invocation) is a Java API that performs a similar function but is object-oriented and Java-specific.

Key Differences

RPC is a protocol used for executing a procedure in a remote system as if it were a local call, simplifying the communication process between computers. In contrast, RMI, specific to Java, enables the invocation of methods on remote Java objects, seamlessly integrating with Java's object-oriented features.

RPC is language-independent and can be implemented in various programming environments, offering flexibility in cross-platform interactions. RMI, however, is designed specifically for Java, ensuring tight integration with Java's features, like garbage collection and exception handling.

In RPC, the focus is on the procedure and the data types being transmitted between systems. RMI extends this by focusing on objects and the methods being invoked, adhering to the principles of object-oriented programming.

RPC abstracts the network communication, allowing developers to focus on the business logic rather than the underlying network details. RMI, while also abstracting the network details, further encapsulates this within the Java ecosystem, offering a more seamless experience for Java developers.
