Cloud Computing is a most recent and hottest buzzword nowadays, emerges as a key service of the Utility or On-demand computing [1] which builds on decade of research in the ground of computer networking, World Wide Web and software services. It put forwards a service oriented architecture, reduced information technology overhead for the end-user, enormous and huge flexibility and reduced total cost of ownership. Recent attacks on the clouds especially DDoS poses as a potential intimidation and danger to this key technology of the expectations and future. In this paper we are going to present a new Cloud Environment and Architecture and an Entropy based ADS approach to mitigate the DDoS attack which further improves network performance in terms of computation time, QoS and HA under Cloud computing environment SaaS, PaaS, IaaS and IT Foundation are four basic types of Cloud Computing [30, 31, 32].
