Cloud computing provides software, storage, computing power and other services to customers from remote data centers over the Web. Demand for cloud-based software is rising rapidly which allows companies to start using new programs faster and at lower cost than traditional products that are installed at a customer's own data center. Cloud computing companies offer cloud computing in developing countries like India, China at prices everyone can afford, so now it is not just top IT companies in developed nations that can take advantage of the cloud but cloud computing providers have now given this ability to smaller companies too in developing nations like India, China etc. This paper reviews different issues influencing the adoption of cloud computing and attempts to derive a framework for successful adoption of cloud computing in organizations. It covers various issues related to resources, security, interoperability and agility. Keywords: Cloud computing, Cloud contributing factors, Information Technology, Computing. Introduction In 1990 Cloud computing was known as ASP. Then in 2001, SaaS was introduced as a term for on-demand computing – this was rebirth of ASP. In1999 the salesforce which was one of the first movers in cloud computing, introduced the concept of delivering enterprise applications via a simple website. Amazon was next on the bandwagon, launching Amazon Web Service in 2002. Then Google Docs introduced in 2006 which brought cloud computing to the forefront of public awareness. Amazon’s Elastic Compute cloud (EC2) as a commercial web service was introduced in 2006 which allowed small companies and individuals to rent computers on which to run their own computer applications. In 2007 an industry-wide collaboration between Google, IBM and a number of universities across the United States. Next in 2008 Eucalyptus introduced the first open source AWS API compatible platform for deploying private clouds, followed by Open Nebula, the first open source software for deploying private and hybrid clouds. In 2009 Microsoft enter into cloud computing with the launch of Windows Azure. Since then many major players enter into cloud computing gradually.
