Integrated Lifecycle of IT Services in a Cloud Environment

Virtualized Service models are now emerging and redefining the way information technology is delivered to end users. Current research is focused on specific pieces like service discovery, composition etc. There is no holistic view of what would constitute a lifecycle of virtualized services delivered on a cloud environment. This paper proposes an integrated methodology that covers the entire service lifecycle. It has divided the IT service lifecycle on the cloud into five phases of requirements, discovery, negotiation, composition, and consumption.
