摘要：Cloud computing is a Service Oriented Architecture which reduces information technology overhead for the end-user and provides great flexibility, reduced total cost of ownership, ondemand services and many other benefits. Hence it delivers all IT related capabilities as services rather than product .Services on cloud are divided into three broad categories: Software as a Service, Infrastructure as a Service & Platform as a Service. Same as services cloud is also classified as Private Cloud, Public Cloud & Hybrid Cloud. Private cloud is gaining popularity, not only among large organizations but also small and medium enterprises. To deploy public or private cloud there are many open source software platforms available such as Eucalyptus, Nimbus, OpenStack, Open Nebula, Cloud Stack and Amazon Web Services. In this paper, we provide a comparative study of three open source cloud management platforms: Eucalyptus, OpenStack and Nimbus. We believe that the comparison presented in this paper would benefit enterprises as well as research institutes in selecting best open source platforms to meet their technology demands.
