Distributed object technology has been used intensely and became an essential part of several solutions, such as middlewares, CMS's, distributed caches, and data grid platforms like Infinispan.

As you saw in detail in Chapter 2, Barriers to Scaling Data, the basic idea behind these platforms is no matter how many nodes are connected through a local area network (LAN). When you interact with a client / server application, the application should provide the same experience that you would expect interacting with a local application with one single node.

No matter the number of nodes in your cluster, the user perceives the system as a single and integrated application.

In this field, we have popular solutions for distributed communication such as Remote Method Invocation (RMI), CORBA, and Web Services (SOAP). These solutions enable distributed objects to interact using protocols adapted for object-oriented systems, where remote clients can access the services...
