Infrastructure as a Service (IaaS) in Centre for Research and Technology Hellas (CERTH)

Abstract

In this paper we explore whether and in what way Cloud Computing and particularly Infrastructure as a Service (I.a.a.S) can improve the services that Information Technology can provide in a research center and specifically in Center for Research and Technology Hellas (CERTH). The characteristics that are being explored are the continuous availability of the services and the resources, the elasticity, which is the variation of them, the reduction of the costs and the savings of the energy that is consumed, the security and the probable locking in a vendor’s services. Next we present 3 implementations of consumer IaaS clouds, the Amazon’s Elastic Compute Cloud (EC2), the Google’s Compute Engine and the Microsoft Azure, as well the OpenStack, the most widespread open source (private or not) cloud development platform.
