On the Evaluation of VM Provisioning Time in Cloud Platforms for Mission-Critical Infrastructures
Cloud Computing has risen a great interest over the last years as it represents an enabling technology for flexible and ubiquitous access over the network to a set of shared computing resources. This work comes from an industrial experience whose aims are to exploit cloud potentialities in order to virtualize complex infrastructures, such as an entire Air Traffic Center (ATC), a clear example of SoS (System of Systems). The use of virtualization is convenient because industry can leverage in-house test-beds to perform distributed testing campaigns in pre-operational phases or to design new automatic fail-over mechanisms for fully distributed systems. In order to realize such mitigation and recovery techniques in the ATC field, indeed, you should entrust a cloud platform which guarantees a low VM-provisioning time with the objective of minimizing the service disruption. In this perspective, after having introduced the principal concepts and factors of the provisioning time, we propose a deep analysis and comparison for two different Infrastructure-as-a-Service (IaaS) platforms, namely OpenStack and OpenNebula (using KVM as hypervisor), that were selected trough a preliminary scouting phase.
