I’ve been watching the cloud scene for a good number of years now and the first iteration of most of the clouds were, well, boring. I’d call these version 0.4 clouds on a good day. Basically they seemed to be made up of standard enterprise storage and servers, running VMware, single tenant except for the rare case of some ‘shared’ storage that was walled off by having the service provider (mostly Telcos) provision and attach storage to specific servers.
Then along came some advances in the software and hardware that actually enabled some basic multitenant capabilities. Of course with the new capabilities came a whole lot more competition as well. To differentiate themselves, some providers went down the acquisition route pretty early with Verizon being one of them (2011). They quickly acquired Terremark for their managed services and their beginnings of a cloud platform. In addition to Terremark, Verizon also acquired CloudSwitch, a cloud software technology that allowed companies to create hybrid clouds between on-premises data centers and public cloud providers as well as between public clouds.
