Architecting Storage for the Internal Cloud: One Step at a Time
10 November 2011
 
Matthew Brisse  

Enterprise organizations are considering internal clouds to increase operational efficiencies, improve business agility, and drive down cost. The internal cloud requires a different storage model than traditional data centers. What does storage for the internal cloud look like? How does storage integrate into infrastructure as a service (IaaS) cloud? What are the key storage considerations organizations need to consider to ensure storage is ready for this transformation? In this Gartner guidance document, Research Director Matthew Brisse examines storage integration for the internal cloud and its transformation into a service-centric storage infrastructure.
