Cameron Purdy explains how a data grid functions by using a partition topology for data access, update, recovery and local storage, accessing data using read/write-through and write behind, and invoking operations through Observable, QueryMap and InvocableMap interfaces. He also offers some examples of data grids solving complex problems and introduces Coherence, Oracle’s data grid solution.

but the deep question is why don't developers get this
My personal opinion is that people learn to code wrong from the beginning. They get taught to express logic by using sequences in code. Tthey use step through debugging. They expect each app to be in a separate VM/object space and never multiple and never shared. And then they expect to build a distributed system as just a bigger app, but it isn't.
Until we remove the things we can't rely upon in distributed systems away from the basic language, we won't end this thinking. i.e. sequence, identity of objects, locking, etc.
