1. Private Cloud Stack Deep Dive Enterprise Cloud Summit

2. Service library What cloud services does the stack offer? (i.e. virtual machines, code execution, large-object storage, message queueing.)

3. OS, language, and API support What operating systems, languages, or APIs can the user employ? (i.e. Python, any OS, etc.)

4. On what stack is it based? (VMWare, Xen, KVM, etc.)

5. Requirements & limitations What are the underlying hardware requirements or constraints? (i.e. pairs of machines; Intel quad-core processors; sub-10-ms latency between nodes)

6. Portability Is the stack portable to other stacks, or to public cloud provider environments? (i.e. can you move an AMI to Amazon?_

7. What standards or de-facto standards does it support?

8. How is it priced? (i.e. by core, by user, open source with a support contract, etc.)

9. Included tools What management tools do you offer? (a screenshot or two is fine here)

10. Capacity, performance, availability What are the capacity, performance, and availability constraints? (i.e. scales to a maximum of 20 nodes)

11. Global distribution Can it work in a distributed, multi-city mode with additional redundancy?
