There seems to be some nice momentum in the blogosphere around Space-Based Architecture and GigaSpaces.
Lets get he most important bit out of the way first. I want to suggest we look at OpenSpaces:
You’ll see that it’s supported by GigaSpaces it was there CEO speaking [It was actually our CTO - Geva]
The lecture was about scalability in tiered systems and the need for replication in each layer and the effects on performance of two phase commits and the amount of network traffic that goes on in a workflow.
There suggestion is to do horizontal scaling with a single virtual machine handling all the layers and then having multiple JVMs. Now doesn’t that sound familiar. The one thing they did suggest was to use Spring as a mechanism for instantiating new JVMs as necessary to manage load with an ‘SLA’ manager to manage the overall system.
The speaker was asked about data volumes, he was talking abut many terabytes of memory but allocating subsets to different JVMs, deja-vu….
