In the context of cloud computing the key question should be whether the underlying infrastructure is supportive of the workflow oriented view of the world.

Characteristics of a cloud environment

• support large number of users ranging from very naive to very sophisticated
• support construction and delivery of curricula for these users
• generate adequate content diversity, quality, and range
• be reliable and cost-effective to operate and maintain

In the context of the VCL technology an image is a tangible abstraction of the software stack.

Service Composition and Provisioning

• sample and combine existing services and images
• create new composites, update them, etc.
• workflow aggregation and automation

Cloud computing research issues

• image and service construction
• Cloud provenance data (process, data, workflow, system or environment)
• optimization
• image portability
• security
• utilization
