Now that you have an idea of what cloud computing is, here are some examples of popular cloud-based applications. There’s a very good chance that everyone in this class is using at least one cloud-based application. Rather than installing software on their computer, users can access these tools with any device that has a web browser and an internet connection – a computer, netbook, or smartphone – to access their data and perform tasks from anywhere at any time. Given the success of these applications, cloud computing has clearly established itself in the consumer market. However, the long-term growth in cloud computing lies in how businesses and organizations will shift their infrastructure and services to a cloud-based platform.
Utility === packaging of computing resources, such as computation and storage, as a metered service. Grid == a form of distributed computing which is composed of a cluster of networked computer to perform large tasks.
Your files and applications that are up in the cloud are also stored redundantly in server farms both around the country and the world. That means if one day you decide to share your coffee addiction with your computer, or maybe Microsoft loses a databank to a tornado you can rest assured your data is safe.
“When It Is Smarter To Rent Than To Buy”
Cloud is simply a metaphor for the internet. An idea of accessing files, software and computing services through the Internet. Users simply rent or accessthe software, paying only for what they use.
History of Cloud Computing Concept dating back to the 1960’s by John McCarthy, a computer scientist, brought up the idea that "computation may someday be organized as a public utility” Idea that revolutionized Cloud Computing: – Utility computing – Grid computingMar 11, 2013
