The term cloud computing is brought to common use and one hears it almost everyday. what actually is cloud computing?
Cloud computing is a common term that is used to represent a hosting service over the internet. The term cloud was inspired by the symbol of a cloud used to represent internet in flowcharts. Cloud computing is classified under three criteria - Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS).
Infrastructure as a Service (IaaS) is largely provided by firms such as Amazon web services. They provide virtual server with unique IP addresses and an on demand storage makes it completely ideal. It costs only for as much as you use.
Platform as a Service (PaaS) is a set of product development tools or software hosted on the product hosted on the provider’s infrastructure. The user or a developer uses this to develop applications on this platform provided by them. Google Apps is a very good example.
Software as a Service (SaaS) provides hardware infrastructure and the required software and the provider acts as a front-end portal. Web-Based E-mail services are a good example.
Hope Steve Ballmer or Bill gates doesn’t have any belief on the Mayan Prophecy. When companies plan to upgrade their system to Windows 7 after the release of its first service pack that would be released anytime next year. Microsoft has started to work on Windows 8 already and have set the target date as 2012.

The companies would soon get fed up on these upgrades which they are forced to make every couple of years. This would become their routine. Why doesn’t Microsoft work on just service packs and patches to improve their Operating Systems instead going on for a total change over every couple of years? Because service packs doesn’t make any money for them.
Soon, the world will turn towards the Open Source software solutions which has become equally competing.
