The 'cloud' is a genuine buzzword, but what is it, how does it affect everything you are doing, and is it anything really
new? What's the cloud? Where's the cloud? Are we in the cloud? All of these are questions you have probably heard or asked yourself. The term "cloud computing" is everywhere. In the simplest terms, cloud computing means accessing and storing information and applications within the Internet instead of your pc 's hard drive. It goes back to the times of flowcharts and presentations that would represent the gigantic server farm infrastructure of the Web as nothing but a white cumulonimbus cloud, a puffy, accepting connections and doling out advice as it floats.
For More Details http://www.offix.co.il What cloud computing isn't around is your hard disk. When you run programs in the hard disk drive or store data on, that's called computing and local storage. All you need is physically close to others on the local network, or you, which means obtaining your information is easy and fast, for that one computer. Working off your hard drive is how the computer industry operated for decades; some would argue it is still superior to cloud computing, for reasons I'll describe shortly. The cloud is also not about having a dedicated network attached storage (NAS) hardware or server in residence.
Storing information on an office or home network does not count as using the cloud. (Nevertheless, some NAS will allow you to remotely get matters over the Net, and there's at least one NAS named "My Cloud," only to keep things confusing.) For it to be considered "cloud computing," you have to get into your info or your software on the internet, or at the minimum, have that data synchronized with other information on the Web. In a big business, you may know all there is always to understand about what exactly is on the opposite side of the connection; as an individual user, you could possibly never have any idea what kind of massive data-processing is occurring on the other end. The end result is the same: with an online connection, cloud computing could be performed anywhere, anytime.
Consumer vs. Business Let's be clear here. We are discussing cloud computing as it affects individual consumers—those folks who sit back at home or in modest-to-medium offices and make use of the Internet on a regular basis. There is an entirely different "cloud" in regards to company. Some companies opt to execute Software as a Service (SaaS), where the company subscribes to a program it gets within the World Wide Web. (Think Salesforce.com.) There is also Platform-as-a-Service (PaaS), where a business can create its custom programs for use by all in the company. (For instance, Netflix provides services to you because itis a customer of the cloud-services at Amazon.) The marketplace was already generating $100 billion a year in 2012. It could be $270 billion by the year 2020.
