We have all been touched in some way shape or form by the cloud. The history of the cloud dates back as far as the 1950s. Back then, a mainframe was so big it took up an entire room. It required a massive amount of space, and electricity which generated superb amounts of heat. These computers were standalone, meaning that the data was held solely with that device. In response, they developed "time sharing" methods, which allowed multiple users to share access to data and CPU time. Nowadays, this concept of “time sharing" is the premise of cloud computing. The next major event in cloud computing history occurred in 1969, when J.C.R. Licklider developed the Advanced Research Projects Agency Network (ARPANET). His desire was that someday all…show more content…
This isn’t strictly for companies and organizations. If you use any kind of social media or online data drive, you 're already using the cloud; you just may not realize it. Accessing programs that run on a remote server are accessed by but not stored on your computer is cloud computing. Cloud computing involves three major premises: Software as a Service, Platform as a Service, and Infrastructure as a Service. Software and Platform as a Service describe the business model of users logging into a centralized hub to access their software products. Users open their files and software only while online, using only their web browser and passwords. It is similar to the idea of mainframe terminals, but cloud computing involves a much larger "cloud" (network) of processing computers at the center. Cloud-based applications—or software as a service (SaaS)—run on computers in the cloud that are owned and operated by others. These computers connect to users’ computers via the Internet and, normally, a web browser. There is no software to purchase, install, update or maintain. This is handled by the service providers. By using the internet browser, applications, and data are accessible from any connected computer. Because access is through the web browser, data is in the cloud. This prevents any data from being lost if there is any issue or problem with the
