I have been thinking about potential of cloud computing since I visited Cloud camp last year, cloud was not much known concept till that time but things have changed. PwC report includes cloud computing in three trends that are changing the face of $250 billion software market. A report by the Centre for Economics and Business Research (CEBR) says that Cloud computing 'could give EU 763bn-euro boost' and could also create 2.4m jobs.
Cloud computing market in India currently stands at USD 10 million and is expected to reach USD 1,084 million by 2015 as per Zinnov Management Consulting Report, 2010.
A trend result of “cloud computing” on google trends (http://www.google.com/trends) reflects how cloud is becoming buzz word by passing years, but when I checked “Software as a Service”, “Platform as a Service” and “Infrastructure as a Service”, I found that not all are trending like cloud computing. Software as a Service has been known for many years, where PaaS and IaaS have still not picked up.
As per survey done by DPCI and Wipro, Software-as-a-Service’ (SaaS) model is the most preferred Cloud service model being used / intended to be used by more than 90% of the organizations surveyed though there is also a growing use or willingness to use ‘Platform-as-a-Service’ (56%), ‘Infrastructure-as-a-Service’ (53%) and ‘Security-as-a-Service’ (53%) delivery.
There are several reasons for adopting Cloud Computing but ‘On Demand Scalability’, ‘Reduction in Capital Expenditure’ and ‘Reduction in Operational Expenditure’ were the top three reasons selected by the surveyed
The same survey revealed that – Data Security & Privacy, Compliance issues, and Legal & Contractual issues were perceived to be the top three challenges faced by the organizations in the adoption of Cloud Computing with 95% of the respondents rating Data Security & Privacy as a ‘Critical’ and ‘Very Important’ challenge.
Large enterprises are hosting non critical business application i.e. Dealer management system, CRM, learning system to public cloud , critical application that demands data to reside within organization system , remains on the private cloud, I expect by next year most of the IT professionals will be knowing what cloud is as they know about XML.
