Supporting the Shift to Cloud Inside, Outside, and Across Organizations Cloud is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, applications) that can be rapidly provisioned and released with minimal management effort or service provider interaction Composition of two or more clouds, private and/or public Public Cloud Infrastructure made available to general public or many industry groups/customers Infrastructure deployed and operated exclusively for an organization or enterprise Private Cloud Hybrid Cloud Source: *National Institute of Standards and Technology, V15 October 2009

Build on 20 Years of Storage Research •  APIs vs. mount points – “no slashes required” –  blocks vs. files vs. objects vs. “APIs” •  App-driven and policy-automated –  self-configuring, self-organizing, self-tuning, self-* •  Built in data services –  self-healing •  Unlimited namespace, dynamic –  billions and billions of objects, large and small •  Native multi-tenancy –  security/auth, monitoring, resource isolation GUI / RAID
