Cloud Computing

Cloud computing is where people share to store their data, which is fast to get started and cost less.  It is like G mail vs. Microsoft exchange.  In Gmail, you don’t need servers, storage, technical team to keep it up and running and no upgrades.  In cloud computing, you just need to log in, customize it and use it for whatever is relevant to your work.  The cloud allows users to run applications and store data online.  The services provide by cloud are software which allow users to run existing online applications, the platform allows users to create their own cloud application using supplier-specific tools and languages, its infrastructure allows users to run any applications they please on cloud hardware of their own choice.  Cloud uses a platform that provides an environment and a set of tools for creating new online applications.  For example, I can use Google app engine to develop, run and maintain any web application within Google for free, Azure is one of Microsoft application can be run on cloud computing, and force.com can allow users to build web applications and host it for free.  The three platforms are all rapid development at low cost, private or public deployment in search engines ant it risk application build on one platform cannot be move to another.  Cloud computing can move existing application from anywhere and store it to cloud.
