AWS does have a virtual private cloud service, which are dedicated, non-multi-tenant infrastructure stacks customers can reserve, but no platform for spinning up an AWS cloud in your own data center. Open source project CloudStack and Eucalyptus, a third-party AWS partner say they do. VMware powers many private clouds with its non-open source products, for example. On the OpenStack side, Piston Cloud Computing Co. has packaged an "enterprise-grade" version of the open source cloud operating system. Red Hat is expected to release its own OpenStack distribution soon, while Ubuntu and SUSE already have.
Jim Curry, general manager of Rackspace's private cloud division, says for many customers he speaks to, it's not a matter of them being anti-public cloud, it's that they believe a private cloud just better suits their needs "We're a hosting company primarily," Curry admits. "But we're not going to argue with them."
Having a common platform between the private cloud that sits behind the customer's firewall and Rackspace's public cloud creates a whole series of advantages too, Rackspace says -- most notably working toward that much-anticipated hybrid cloud environment. Sanchez says many customers already have some hybrid cloud-like setups. Using configuration management tools like Chef or even third-party options like RightScale, customers can pick which environment certain workloads run in, be it the public or private cloud. But there's still work to be done in this area to allow live migrations of workloads across the environments. Further developing the underlying network connectivity between the public and private clouds is a key to achieving that, Sanchez says.
