I just read a post on Cloud Computing Journal that suggests that RackSpace will be rolling out Drizzle later this year on their Cloud, and are probably going to replace MySQL in the process. Drizzle is a cloud-directed, Linux-leaning, stripped-down, hitherto for unsupported, GPL 2 MySQL 6.0 fork that Rackspace is betting will infinitely scale, or at least scale better than MySQL. But what will that mean for the websites hosted on the RackSpace Cloud?
