Analysis of Areas of Research Interest in Cloud Computing

In the study of cloud computing and its applications, topics such as understanding computing resource utilization, differences between grid and cloud computing, relationship between high performance computers and the cloud computing centre, and security and standards have attracted intense research interest. This paper analyzes these topics and concludes that virtualization provides Internet users with intensive, large-scale professional services; grid computing involves utilizing many computers for one large-scale computing task, while cloud computing involves one platform for many services. A high performance computer in the high performance computer center may be unsuitable for a cloud computing; security in cloud computing focuses on trust and trust management between service suppliers and consumers; and based on existing standards in cloud computing, new standards should be developed to realize interoperability between services.
