So What Is Cloud Computing Exactly ?

The Wikipedia says "Cloud computing is a Internet-based computing, whereby shared resources, software, and information are provided to computers and other devices on demand, like the electricity grid" .But this is all about the technical jargon in a lay mans word what I would say is that cloud computing is what a Taxi is to an Automobile its basically A Pay As You go kind of a model in which an Individual,SME,Corporates hire or lend Computing services .So lets assume you have a website which has a regular number of hits but on certain occasions you see that the Hits are almost double of what you had expected, In that case the only option left traditionally is to Purchase a new Machine and configure the same Web server or have virtualisation implemented.But these technologies come at a cost which you may have to invest for a short period of time(In this case for the days in which you see above average Hits ).So here is where cloud computing comes to your rescue.So in case your server was on the cloud all you have to do is add a couple of servers which are a replication of the original one and use them untill you require them and once done you can Bundle the server or simply terminate .Even the scaling can be automated .In coming days I shall update the various types of Clouds that are picking up in the Tech World
