While executives around the world are discovering ingenious ways to put cloud computing to work, one might wonder - how much cloud computing do we need in 2011? According to Julian Lewis, Managing Director of Positive Computing a supplier of IT support and consultancy based in Reading, Berkshire, "We are now firmly in the cloud computing age and most of us have at least some of our computing in the cloud." The cloud gives IT professionals a massive opportunity to bring to bear their experience in a new arena made possible by the march to super-fast internet from all locations. Why are organizations around the world adopting Cloud Computing? and how do the trends change in the next couple of years? Here we investigate some figures from Accenture Institute for High Performance Global Cloud Computing Survey.
According to this survey (comprised of executives from industries), the organizations are adopting cloud computing for critical and less important applications in various industries. The use of cloud computing is going to increase significantly in the next 2 years with the maximum critical application in the Financial Services and High Tech industry.
While many get confused as to whether Cloud Computing is a technology or a service, it is interesting to note that cloud computing is seen by some as more fitting than “cloud” or “utility” computing, an easy way to provide computing services over the internet.
Cloud computing services are being used as a software service like cloud-based applications, as an infrastructure service for processing and storing data, as a process service with business processes built upon cloud applications, as well as a platform service where organizations are developing, testing and running applications on clouds or for clouds. In the above survey, nearly 50% of the executives indicated that the cloud computing is mainly being used for public process and software services in their own organizations.
Having recognized the reasons for adoption of cloud computing, it is important to understand how companies implement cloud computing and what does it really entail. Using cloud computing for several services involves seamless use of several technologies at hand. Some of the foundation technologies for Cloud Computing are:
- Virtualization: It is a way to run more applications or store more data on fewer computers.
- Grid computing: It divides processing among computers; enables speed and scalability.
- Broadband internet: It enables vast amounts of data to quickly travel over the Internet.
- Web 2.0: It comprises of all the applications and technologies that make the Web a vehicle for collaboration.
- Service-oriented architecture: It involves the designs systems that act like interconnected services.
How much can cloud computing services benefit each organization really depends on the extent of use and application of cloud computing services within their system. While reducing up-front IT costs / capital expenditures is one of the obvious reasons, there are many applications of cloud computing in an environment where the business processes are changing rapidly and there is an underlying need of improvising analytical capabilities of the organizational system.
