Capable of virtualization to run multiplesystems 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
buildinge.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
