Cloud Computing Architectures: A Retrospective Study

Now-a-days cloud computing is popular and several information technology corporate companies have started using their cloud computing architectures. Cloud computing plays a key role for distribution of resources such as storage devices and software. Cloud computing reduce the management difficulties and improves the efficiency of services. Generally cloud computing architectures are broadly separated into cloud platform architecture and cloud application architecture. This paper describes a review of different categories of cloud computing architectures such as cloud computing architectures such as service-oriented cloud computing architecture, Microsoft cloud computing architecture, Abicloud cloud computing architecture, Eucalyptus cloud architecture, Nimbus cloud computing architecture, Open Nebula cloud computing architecture, cloud computing open architecture, and an intelligent and energy efficient computing architecture. The work presented identifies different research areas includes wireless communication in cloud computing and security in cloud computing architectures.
