Cloud computing is somewhat like the sun on a cloudy day; you cannot see it, but you know it is there. You do not get to see what is on the other side of the clouds themselves, but you know there is something on the other side from which you can get the benefits of its presence and service. Cloud computing is one of the latest revolutionary computing concepts associated to the Internet and the way we will use our computers in the near future. The word “cloud” in cloud computing means that the architecture taking the form of a cloud which is easily assessable for users from anywhere in the world on demand. Cloud computing lets you use files and applications over the Internet. I will discuss the definition of cloud computing, some of the history of cloud computing, different types of cloud computing, the infrastructure and how cloud computing works. In addition, I will discuss the drawbacks, privacy issues that are involved in cloud computing. I will discuss the latest innovations and the latest inventions as well. I hope you enjoy reading this research paper as much as I have enjoyed completing it. Let us explore this amazing technology together. We have a lot to look forward to in the wonderful world of technology.

What exactly is cloud computing? There are actually several answers to what cloud computing is; depending on the person’s view point. The main definition of cloud computing according to IT experts is that cloud computing is a solution that helps companies increase productivity while reducing the cost of IT infrastructure. Whereas, other individuals would define cloud computing as an alternative source for storing data, photos, and important files in the event your PC crashes. This allows your valuable data to be restored as if the PC crash never happened. Cloud computing also provides a wide range of access to software and hardware applications; available on a “pay-as-you-go” basis. Cloud Computing Logical Diagram

Cloud computing involves the use of the Internet, commonly referred to as “the cloud,” to run hardware and software applications and store important data for backup and disaster recovery. The name “cloud computing,” comes from the use of cloud shaped symbols often used to represent the Internet in flowcharts and diagrams.

Cloud computing usually has a front end, which is what the user sees, and a back end, which does all the work. Cloud computing shares some similarities with an older model of computing called timesharing. A timesharing computer system connects multiple users to a single computer processor through dumb terminals, which have a keyboard and monitor, but leave the computing to the central machine. HISTORY ON CLOUD COMPUTING

Many people tout cloud computing as the next big thing but the idea is almost as old as the computer itself.
Cloud computing actually dates back to the 1950s when large-scale mainframes became available in academia and corporations, accessible via thin clients/terminal computers. Because mainframes were so expensive, it was important to find ways to get a bigger return on the investment, allowing multiple users to share both the physical access to the computer and to share the CPU time; eliminating periods of...
