Over past years, IT complexity has grown while efficiency promoted; Virtualization reverses this track simplifying IT infrastructure, improving efficiency by performing more with less effort. Virtualization lets the application run in a few physical servers where each App operates in a separate container called a virtual machine. VM is entirely isolated, but computer resources like processor, storage, and networking are shared among running Apps and delivered dynamically through software called

Without service running at full capacity, the user does not require many virtual machines depending on the demand, which can get higher value by improving performance, lower cost, less complexity, and faster maintenance. According to the NIST definition, there are three models (SaaS, PaaS, and IaaS) (Mell & Grance, 2011, p.3). Amazon AWS and Microsoft are two popular platforms dominating the market of Platform-as-a-service (PaaS) and infrastructure-as-aservice (IaaS); each one has its use-cases. Through this case study, we will examine the organization's environment and evaluate its preparedness for Virtualization according to the recommended business model within the AWS infrastructure service as an example of cloud service with high availability and fault tolerance configuration. Also, the study will touch Windows Azure capabilities for virtual machines and managing a hybrid cloud, including Windows Azure's Internet as a Service (IaaS) and storage capabilities.
