While at SpringOne2GX back in October, the thought occurred to me that Terracotta would make a really interesting acquisition target for VMware. VMware has had some pretty amazing virtualization technology for a while, including the ability to migrate live virtual machines between physical boxes, but it has (as far as I know) all been focused on low-level infrastructural magic. That changed with their acquisition of SpringSource last year, which followed shortly after SpringSource's acquisition of Cloud Foundry. Now, if you just add Terracotta to the mix, you could make it possible to easily deploy an auto-scaling clustered app to the cloud. Doesn't that sound interesting? Add to that the fact that Terracotta has been a sponsor for at least the last two SpringOne conferences in the U.S., SpringSource and Terracotta have already collaborated to build a sample app, and Terracotta brings Ehcache (easy clustered caching) to the table. Seems like a potent combination to me.
I have no concrete grounds for this prediction beyond the points above, but I wanted to get the idea out there now just in case it actually happens. ;)
Update (May 26, 2010): Unfortunately, with the announcement of SpringSource/VMware's acquisition of Gemstone, my prediction is now unlikely to occur. Oh, well. Plenty of others before me have been wrong. ;)
