OnApp is one of the most interesting European cloud players, as it offers traditional hosting providers a way to fight Amazon(s amzn) by federating the spare capacity in their data centers -- it also has more than 500 of these providers as customers around the world, so this is a serious endeavor. Now the company has launched version 3 of the OnApp Cloud platform, taking its distributed storage piece out of beta, improving its content delivery network offering and adding support for VMware hypervisors.
Federation/Distributed Capacity has merit for specific types of workloads. It will be interesting to see the relationship of the type of content vs. performance.
