Interesting stuff. Here is a snippet…
Scale your application, while leaving your existing database untouched by front-ending the database with In-Memory-Data-Grid (IMDG) or caching technologies. The database acts as a persistence store in the background. I refer to this approach as Persistence as a Service (PaaS).
Although I do question how reliable the background persistence to a database is. Seems another layer of complexity that requires understanding in case it has issues of its own. After lookign at the Gigaspaces website, it looks like a typical Java-powered auto-generated website with tons of information all over the place but hard to find a good starting point (Yes I found the tutorials thank you) or any great documentation for a newbie.
