What is Cloud Computing?
cloud computing \noun;
style of computing where massively scalable IT-related capabilities are provided “as a service” using Internet technologies to multiple customers

Cloud Computing is more than a technology. It is more than a platform. It is more than just a hosting provider. It is more than just an application hosted as a service. It is more than providing storage services on the Internet. It is a combination of all the above. In today’s economic environment as Enterprises try to balance out and optimize their IT budgets, Cloud computing can be an effective strategy to reduce the IT operations and management costs and free up critical resources and budget 1

for discretionary innovative projects. Typically, Enterprises have a 80/20 split between regular ongoing IT operations cost which includes hardware, software licensing costs, development, data center maintenance etc Vs new investment for solving critical business needs which is critical for businesses to survive in these challenging times. Cloud Computing can have a significant impact in this by reducing the footprint of IT operations by taking out the upfront capital investments needed for hardware and software licensing. It enables a Use what you Need and Pay for what you Use cost model. This will enable businesses to invest on innovative solutions that will help them address key customer challenges instead of worrying about operational details. There is one thing that industry leaders and analysts agree on; Cloud Computing will be a transformative phenomenon in 2009. According to IDC, spending on Cloud Services is expected to grow over five times that of traditional On-Premise IT. Even though IT budgets are being slashed, enterprises cannot afford to stop investing in IT because IT is what helps them gain and maintain a competitive advantage. The Cloud offerings will help enterprises to continue to invest in IT without having to take up big budget and long term IT projects. Investment in IT changes from being a Capital Expenditure to Operating Expenditure. Enterprises can become agile and harness the power of Information Technology to drive unprecedented customer value.

What technologies constitute cloud computing?
Cloud Computing is a paradigm that is composed several Strata of Services. These include services like Infrastructure as a Service, Storage as a Service, Platform as a Service and Software as a Service. Different Cloud Providers have developed various access models to these services. The access to these Services are based on standard Internet Protocols like HTTP, SOAP, REST, XML and the infrastructure is based on widely used technologies including Virtualization, hosting. Cloud Computing is the maturation and coming together of several prior computing concepts like Grid Computing, ASP, Server Hosting, Utility Computing and Virtualization.
