VMM-level distributed transparency provisioning using Cloud infrastructure technology

摘要

Cloud computing is a paradigm of virtualized distributed environments with virtual machines as their primary building blocks. Being a distributed system, Cloud computing paradigm needs a new layer of software to provide different aspects of distribution transparency at virtual machine level. This software layer called Cloud infrastructure is deployed above the virtual machine monitor layer. In this paper, we present some of the Cloud infrastructure technology challenges such as image management and scheduling in Cloud distributed environments. In addition, we argue how some prominent Cloud infrastructures such as Eucalyptus and OpenNebula tackle these challenges. Finally, as a proof-of-concept, we show how the deployment of different transparent network services is possible using a specific Cloud infrastructure service through the mentioned technology.
