Systems become moredistributed, scalable, reliable, cost effective, etc,. are key advantages ofthe Cloud based ITenterprises.Cloudcomputing(Carr&Yu,2008)hasbeenexpressedinmanywaysbydifferentorgan- izationsbasedontheapplicationareas.Sincetherearenostandarddefinitionshasbeen adopted until now. The commonly useddefinition for the cloud(Chan, Mei, & Zhang, 2009)standsforcomputingwith:“Common,Location-independent,OnlineUtilitythat is available onDemand”. Clouds provide various service models they are IaaS (Infra-structure as a service), PaaS (Platform as a service) and SaaS (Softwareas a Service).
