SOA on Grid and relocatable BPEL processes
It most of the obvious target use cases like:
In memory persistence caching of DB (asynchronous write)
Performance improvement of BPEL PDS - Dehydration (process data/state storage)
But most importantly, the article introduced one important concept, we had brainstormed earlier, that is re-locatable BPEL process to minimize a data serialization. Why bring a large data across a network when a process can itself continue from a node on/closer to the node having data. e.g. Apps adapters.
Certainly doing such agile services would provide a stateful however relocatable services resulting into high performance and high availability.
