Today things have gone full circle with Technology. Over 20 years ago data and applications were placed on central servers under the Unix and Main Frame environments and now in today’s world it is now going back to that idea. Cloud computing is just a BUZZ word used as a sales tool by people who barely understand anything about technology. Even the phrase “In The Cloud” was used by telephone companies in the old days. The phrase “In The Cloud” has now been reborn and excepted as some kind of new technology.
Other names for Cloud Computing can also be called “Thin Client Technology”. So the question is what is it really and how does it work?
To answer the question we look back in the early 90’s and there was one widely known product that was used to remote control a workstation over a 33KB modem phone connection and its name was PC Anywhere. The data and applications are left on the computer you access and then only the keyboard strokes and graphics are moved between the “Host” machine and the computer accessing the Host.
Using that concept you will not require large amounts of bandwidth to run applications remotely because the packets of data moving between the host computer and the remote computer will be miniscule.
Other methods of low bandwidth connections long ago have been made using Unix and mainframes central servers. Programs were written using TEXT not graphics and these programs were placed on a Unix server or mainframe. Every Dumb Terminal in your building would connect to a server or group of servers. There was no OS loaded on the terminals. The programs ran fast and were secure because there was no way to get the data off the central server and the stations the users ran had no drives and they had no data stored on them. Once again the Dumb Terminal transfers only keyboard and graphics to and from the servers the data and applications stay on the server and never move to a workstation.
