When OpenSpaces was first released, one of its core features was Space Based Remoting.
Based on the Space as a discovery, transport, load balancing and failover capabilties, this remoting mechanism provided a a drop in replacement for other remoting implementations, allowing for exposed services to be highly available and redundant and for remote client to get fault tolerance and load balancing out of the box without changing a single line of code.
With 6.5, we have decided to change the name of this feature to the Service Virtualization Framework (SVF) as we feel it has become much more than just a remoting implementation, and better describes the overall value it can bring to applications, by virtualizing any service object across the GigaSpaces grid.
If you want to get more details about how this framework works and what are the benefits it gives you over ordinary remoting implementations, please check out this post .
