My Introduction With Cloud Computing

June 15, 2009 at 3:05 pm 6 comments

Till today, I wasn’t much into the technicalities of cloud computing. It flip-flopped several times through my eyes but I never bothered to investigate in details. The recent write up of Dion Hinchcliffe, where he talks about Cloud Computing and Open Source face off, dragged my attention to get deep into this. The simple explanation comes from Wikipedia. It treats cloud computing as a combination of three different services.

Cloud Computing = IaaS + PaaS + SaaS

*IaaS – Infrastructure as a Service

*PaaS – Platform as a Service

*SaaS – Software as a Service


Going further gives us much more interesting facts. When the world was busy getting over the high CapEx + OpEx and striving to derive a need based expenditure module, a Professor of Information Systems & Operations Management Ramnath Chellappa came and gave the theory of Cloud Computing. He defines it as “a computing paradigm where the boundaries of computing will be determined by economic rationale rather than technical limits”. It solves the problem of high CapEx and OpEx. It also gives organizations a need based expenditure model. Looks simple but it isn’t that easy.

Some biggies of IT industry talk about Cloud Computing in their own words here. They make it look simple though for me the implementation par t is more interesting to watch. I browsed little further and got few white papers and few books on this. Next task for me would be looking into these extensive details.

When I look at adaptation and acceptability, it looks gloomy. IBM is already working towards its solution for Cloud Computing. They are now targeting software development and testing  sector as well. Dave Greenfield predicts a growth in could computing security in 2009.These talks are definitely creating a favorable environment.

I will continue to gather and share more information on this.

    I believe that cloud computing from a business perspective is definitely the future of computing. It will provide many benefits to businesses, but in the long-run, they will likely have to develop in-house “mini” clouds, as most businesses will be uncomfortable leaving their private data sitting on a server somewhere on the web.
