Terracotta Discussion Forums (LEGACY READ-ONLY ARCHIVE)

I see Terracotta positioned for scalability and for "fault tolerance", and that's the area of interest for me at the moment. What I'm wondering is if the fault tolerance is referring strictly to a cluster model, or if there is something more that's not immediately obvious.

I view clustering as a load balancing approach, which certainly has value, but is not something that I imagine being spread between a primary data center and remote disaster recovery site.

Would or could terracotta be used in a fail-over mode between geographically dispersed systems?
