Capable of virtualization to run multiple systems and take advantage of better use of CPU cycles and storage Massive clusters of low cost commodity computers - Compute cloud (e.g. Amazon Elastic Cloud) - Data cloud (e.g. Amazon S3) - Public cloud - Private cloud

Private cloud: specifications

Entire software stack is open source
Management of the cloud must be via easy to use interfaces, and there should not be excessive systems administration costs
Compute and storage systems must be fully scalable by adding additional elements
There should be a capabilty to cost and charge for hosted virtualized systems

Building our ecosystem

Identify key support people
Where necessary, send them for training and collaboration building

e.g. Univ North Carolina (iRODS)
e.g. Sun Microsystems (Cloud)
e.g. DuraSpace (Fedora)

Collaboration with hardware vendor to innovate together

Current status

High level design complete
Teleconference with engineer and others from Sun microsystems to determine feasibility
Compiling budgets
Will hold a planning meeting with Sun soon
Plan to have in place by mid-November
