What is the cloud computing? Where is the cloud? Is it that we are in the cloud now? These are all the questions you’ve most likely heard or even asked yourself. The expression “Cloud computing” is all around.

In the most simplest terms, cloud computing means storing and accessing data on the internet rather than your PC’s hard drive. The cloud is only an allegory for the Internet. It retreats to the times of flowcharts and presentations that would speak to the immense server-ranch foundation of the Internet as only a puffy, white cumulonimbus cloud, receiving connections and doling out data as it floats. The most simple and understandable example of cloud application around us are gmail and yahoo dont need any server or softwares to access these applications simply you just need a internet connection.

Cloud computing is not about is your hard drive. When you store information on or run programs from the hard drive, that is called local storage and computing. All that you need is physically near you, which implies getting to your information is quick and simple, for that one PC, or others on the neighborhood system. Working off your hard drive is the way the PC business worked for quite a long time.; some count it’s still better than cloud computing, for reasons I’ll explain in no time.

The cloud is additionally not about having a dedicated network attached storage(NAS) hardware or server in living arrangement.Storing data on a home or office system does not consider using the cloud. (In some cases, a few NAS will let you remotely get to things over the Internet, and there’s atleast one NAS named “My Cloud,” just to keep things confounding.)

For it to be considered “cloud computing,” you need to acces to your information or your projects over the Internet, or at the very least, have that information synchronized with other data over the Web. In a big business, you might know everything to think about what’s on the opposite side of the connection; as an individual client, you might never have any thought what sort of monstrous information handling is going on the other side. The final result is the same: with an online connection, cloud computing should be possible anyplace, at anytime.

Customer vs. Business

How about we be clear here. We’re discussing cloud computing as it effects singular purchasers—those of us who sit back at home or in little to-medium workplaces and utilize the Internet all the time.

There is totally different “cloud” with regards to business.Some organizations choose to implement Software-as-a-Service (SaaS), where the business subscribes to an application it gets to over the Internet. There’s likewise Platform-as-a-Service (PaaS), where a business can make its own particular custom applications for use by all in the organization. Also, keep in mind the mighty Infrastructure-as-a-Service (IaaS), where players like Amazon, Microsoft, Google, and Rackspace provide a backbone that can be “rented out” by different organizations. (Forexample, Netflix give services to you because its a customer of cloud-services at the Amazon.

Obviously, cloud computing is huge business: The business sector was at that point creating $100 billion a year in 2012. It could be $270 billion by the year 2020.
