Recall RMI
 RMI (Remote Method Invocation)
 use the Java programming language and development environment to write object-
oriented programming in which objects on different computers can interact in a
distributed network.
 RMI is the Java version of what is generally known as a remote procedure call (RPC),
but with the ability to pass one or more objects along with the request
RPC
 RPC (Remote Procedure Call)
 RPC and RMI are two mechanisms that allow the user to invoke or call processes that
will run on a different computer from the one the user is using.
RMI vs RPC
 The main difference between the two is the approach or paradigm used.
 RMI uses an object oriented paradigm where the user needs to know the object and
the method of the object he needs to invoke.
 RPC isn’t object oriented and doesn’t deal with objects. Rather, it calls specific
subroutines that are already established.
So..
 RMI is object oriented while RPC isn’t
 RPC is C based while RMI is Java only
 RMI invokes methods while RPC invokes functions
