Recent trends in Cloud computing
Cloud computing is a pay per use model; it is based on service we are using. There are different types of cloud service available- Infrastructure as a service(IaaS), Platform as a service (PaaS) and Software as a service, researchers also have proposed XaaS (Anything as a service) here X could be Database, Network and many more. In the last decades Cloud Computing changed enormously. There is a increment not only in number of cloud provider but also the cloud Infrastructure that was initially limited to single provider who is having his own data centers. Now there is a need to develop infrastructure from multiple providers so that the power consumption could be reduced and enhance the better service to the consumer. There is also possibility of decentralizing computing away from data centers is now evolving. This trend has resulted to develop a variety of computing architecture which will offer future cloud infrastructure
