ABSTRACT
Almost everything in the digital world is connected to the cloud in some way or another — unless it’s specifically kept in local storage for security reasons. As tech giants and start-ups find new ways to organize process and present data cloud computing will become a more and more integral part of our lives. Over the next 10-15 years we can expect cloud computing to quickly evolve, and become so ubiquitous, that the concepts we label as ‘cloud’ will simply be known as ‘computing. Cloud computing leading feature is the availability of all required software on the web. The five cloud attributes and the three service delivery models are highlighted in this paper. The four basic deployment models public cloud, private cloud, hybrid cloud and community cloud are also discussed. The future of cloud computing will most likely represent a combination of cloud based software products and on premises compute to create a hybrid IT solution that balances the scalability and flexibility associated with cloud and the security and control of a private data centre. The real future of cloud will be easy access and consumption of any data and services in the cloud. This paper will address the strengths and weaknesses of cloud computing and addresses its future challenges.
