From time to time, there is the need for a survey of different forms of computer services delivery. Personal Cloud computing is a technology which satisfies customers dynamic resource demands and makes the job easier to work on all platforms for the user. Cloud computing is the delivery of computing services over the Internet. Security is the main criteria when working on cloud, as the third party involvement will always be there. It is therefore recommended in this paper that secure architecture should be used to provide services through the cloud. The extensive use of virtualization in implementing cloud infrastructure brings unique security concerns for customers or tenants of a personal cloud service. It is observed that virtualization alters the relationship between the OS and underlying hardware -be it computing, storage or even networking. Hence, identified methods show how to overcome the security issues of the cloud.
