Widespread interest and excitement about cloud computing have emanated from businesses, government agencies, Information Technology (IT) executives, and other organizations seeking more dynamic, resilient and cost-effective Information Technology systems than previous generations of technology allowed.
Although the term cloud may connote a transitory or short-lived quality to the type of computing it describes, the benefits of cloud computing to customers are very tangible. Businesses around the world are adopting cloud computing in recognition of its potential to usher in a new era of responsiveness, effectiveness and efficiency in Information Technology service delivery.
Cloud computing technology is a type of computing technology whose foundation is the delivery of services, software, and processing capacity using private or public networks. The focus of cloud computing technology is the user experience, and the essence is to decouple the delivery of computing services from the underlying technology.
Cloud computing technology is incredibly user friendly. The technology behind the cloud remains invisible to the end user. Cloud computing is an emerging approach to shared infrastructure in which large pools of systems are linked together in private or public networks to provide Information Technology (IT) services. The need for such environments is fueled by dramatic growth in connected devices, real-time data streams and the adoption of service oriented architectures and Web applications, such as mashups, open collaboration, social networking and mobile commerce.
With cloud computing, Information Technology (IT) professionals can devote more energy to enhancing the value of using Information Technology for their enterprises and less on the day to day challenges of Information Technology. Cloud computing supports massive scalability to meet periods of peaks in demand while avoiding extended periods of under-utilized IT capacity. With the click of a mouse, services can be quickly expanded or contracted without requiring expenditure in deploying extra resources. The benefits include lower cost of ownership, which drives higher profitability, enabling you to invest much more in expanding your business. Cloud computing also yields significant cost savings in the real estate required for the data center as well as power and cooling costs.
Many application programs such as QuickBooks, Peachtree, Windows Server, etc. can be easily hosted in the cloud. Cloud computing fosters business innovation by enabling organizations to explore quickly and cost effectively the potential of new, IT-enabled business enhancements that can grow with unprecedented scale.
Cloud computing represents the next phase in the logical evolution in the delivery of Information Technology (IT) services, building on previous innovations that include grid, on-demand, and utility computing.
