Cloud computing technology use central server and provide applications as services to users. The use of cloud computing will reduce the cost of hardware and software ownership and its maintenance. Many surveys proved cloud computing reduces total cost of ownership. But due to centralized server approach there is always risk to system security. All applications required by different set of users are stored in single CPU and there is a chance for attackers to hack important data. If organization implements separate central servers then it will again reduce the cost of hardware and software ownership.
