What are the advantages of RMI over sockets?

RMI stands for Remote Method Invocation. It is a distributed environment technology. It provides object-to-object communication between different Java Virtual Machines (JVMs). It is basically meant for developing large-scale systems, as it allows distribution of resources and processing load across the network. RMI can also be expressed as follows:

RMI = Sockets + Object Serialization + Utilities

Note: A communication overhead is involved when using RMI by the use of RMI registry and client stubs or proxies that make remote invocations transparent. The RMI remote object needs a proxy, which slows the performance down.
