Abstract

Cloud computing is a style of computing where scalable IT-related capabilities are provided “as a service” to external customers based on a network such as Internet. Although there are some issues, such as security, that cause cloud clients to worry about, with the growing of cloud computing, data security may become one of the most important concerns for IT governments to move their application and data from local data centers to the cloud environments. For enterprises, it is important to trade off among risks and benefits introduced by cloud technology before deciding to move to the cloud environments. In this paper, I try to summarize cloud computing RAS (Reliability, Availability, and Security) concerns. Additionally, I introduce available solutions for some of those concerns.
