Services Portability is Not Easy!Portability (install, operate, regulate, market/exchange) Many challenges with real-world services Complex software and hardware infratructureComplicated requirements, Sequence-of-operation, relationships, groupings, capacity, dependency, configuration, and much, much more!

Approach 1: Moving virtual images? Uncoordinated, unsynchronized snapshots of virtual components Operation at the component level onlyNo understanding of the overall service

Network4Services Portability is Not Easy!Portability (install, operate, regulate, market/exchange) Many challenges with real-world services Complex software and hardware infratructureComplicated requirements, Sequence-of-operation, relationships, groupings, capacity, dependency, configuration, and much, much more!

Approach 2: Bundle the service components in a package for a service provider? Not adequate! Another provider might not have a clue how install, operate, regulate, manage the service Detailed skills and information needed!
