Analysis on Cloud Computing Architectures

Abstract

Cloud computing is an evolving technique and emerged the entire IT industry in recent years. It transformed the IT landscape and brought the world in the hands of public. One can access the resources available on cloud on pay-as-you-use basis, like applications and infrastructure provided by cloud providers in the form of applications already deployed by cloud providers for use by the cloud users. These services are developed, tested and deployed before they brought into use. Another feature of cloud computing is its massive storage infrastructure made available for database and data supplied by the user. The cloud has several unique architectures and many more are still evolving. The services like SaaS, PaaS and the IaaS are deployed on private, public, community and hybrid clouds. In this paper we discuss the present developments in the cloud computing architecture and also try to present feasible guidance for further processing. Papers published in journals, conferences, white papers are analyzed. We attempt to identify, examine and explain the current trends and development in cloud computing architecture. However, only 13% of the papers examined discussed Others-as-a-Service, while only 26% of the papers reviewed considered issues relating to the major actors involved in cloud computing. This will beneficial to cloud providers, users, and researchers alike
