Context Cloud Computing is the new trend in the IT industry. Traditionally obtaining servers was quiet time consuming for companies. The whole process of research on what kind of hardware to buy, get budget approval, purchase the hardware and get access to the servers could take weeks or months. In order to save time and reduce expenses, most companies are moving towards the cloud. One of the known cloud providers is Amazon Elastic Compute Cloud (EC2). Amazon EC2 makes it easy for companies to obtain virtual servers (known as computer instances) in a cloud quickly and inexpensively. Another advantage of using Amazon EC2 is the flexibility that they offer, so the companies can even import/export the Virtual Machines (VM) that they have built which meets the companies IT security, configuration, management and compliance requirements into Amazon EC2. Objectives In this thesis, we investigate importing a VM running on VMware into Amazon EC2. In addition, we make a performance comparison between a VM running on VMware and the VM with same image running on Amazon EC2.
