I was in a technical seminar today, one speaker gave a brief talk on this topic in his presentation. This is my first time to get a feel of such concept. My instinct tells me it's a stuff of interesting.
My first impression with it is the concept bears a combination of following characteristics:
Representational State Transfer (REST),Service-oriented architecture (SOA) Event-driven architecture (EDA)Grid computing .Shared-Nothing Architecture ,
Introduction on wikipedia can be found at: http://en.wikipedia.org/wiki/Space-based_architecture
Products of this regard include GigaSpaces XAP, Oracle Coherence, Hazelcast.
Just leave a note here to remind me to get a thorough read later.
