Abstract

Cloud Computing is a dynamic and emerging paradigm for parallel and distributed computing in which cloud\nservice providers provides the resources like infrastructure, platform, software etc. to the clients. Whenever they request for\nthe resources, they have to pay according to their usage. This enables everyone to access the resources quite easily over the\nshared network. But as clients are concerned about the confidentiality of their data, there is a need of evaluating and\nanalysing the problems related to the security of the service provided over cloud. The purpose of this review paper is to\nprovide comparative study of the existing cloud simulation tools to directly analyse the behaviour of cloud in terms of\nvarious parameters.
