CLOUD COMPUTING : THE COMPUTING GRID OF THE FUTURE
Cloud computing will soon be the biggest game changing development in technology since internet.
There will be a computer in every device that you come across but the computer as we know it today will be nowhere. The computers of the future will be called tablets, smart phones, access devices and televisions.
Like most technology jargons, cloud computing is best explained through users.
WHAT IS CLOUD COMPUTING ? Cloud refers to a computer network or internet, depending on how a particular service is being delivered. Computing through cloud, or delivery of software business applications through a given network allows customers and users to use a service without owning any hardware infrastructure or software licences.
HOW IT WORKS ? A service provider such as Wipro or Infosys can buy licensing rights for an ERP software from say SAP, and deliver it to a customer on-demand, taking care of everything from licensing, hosting, maintenance and support of the system.
HOW BIG IS THE MARKET ? A Zinnov study says that Indian cloud services market will be a worth $1 billion by 2012.
To understand what cloud based computing can do for mankind we need to unwind time and retrace the path followed by electricity from discovery to the current day power grids. We can trace three major phases in which electricity was made available to all in a true utility model.
It all starts off with the discovery of electricity and usage by a few as novelty. This phase was marked with limited equipment which could use this power source. If we now jump into the world of computing, it followed a similar path of getting into research setups to start with very different interfaces which itself was restrictive and needed high skill to operate.
