Cloud Computing RAS issues and challenges

Farzad Sabahi


Cloud computing is one of today’s most exciting technology due to its cost-reducing, flexibility, and scalability. In the last few years, cloud computing has grown from being a promising business idea to one of the fastest growing parts of the IT industry. But when talking about cloud computing, IT organizations concern about critical issues that exist in cloud such as security. These types of concerns originated because of the data will be stored remotely from the customer's location; perhaps scattered all over the globe. The risk of security and privacy may be lower overall with cloud computing than applies in the status quo. In assessing whether to move to cloud computing, it is important to compare with the benefits and risks of the status quo. Consequently, there are some issues that effectuate cloud clients need more time to think about moving to cloud environments. But Security-related topics is one of the most arguable issues in the cloud computing which caused several enterprises looks to this technology uncertainly and move toward it warily. In this paper I try to summarize cloud computing RAS (Reliability, Availability, and Security) issues and propose feasible and available solution for some of them.
