The use of “Cloud computing,” as it is termed, may become secure through quantum entanglements, something Einstein called “spooky action at a distance.”
No need to go into the science of quantum entanglements and how they make your data secure-the important point is the resurgence of cloud computing.
Resurgence? Isn’t cloud computing a new thing—the newest latest thing? No, it is just a new name for an old thing.
Back in those early days of computers, when IBM mainframes ruled, people accessed mainframe computers through “dumb” terminals. The terminal was “dumb” because it had no computing power of its own other than to display information from the mainframe and allow the user to input new information to update the files in the mainframe.
When I ran Citibank’s datacenter in Singapore, we were able to service 100 dumb terminals in Saudi Arabia with a slow 14 kilobit per second connection—a connection about 1,000 times slower than that of most Internet connections. That wasn’t too bad. It was also very economical.
With the so-called and premature, “death of the PC,” we are getting back to fairly dumb terminals such as iPads. They leave the processing and the heavy lifting to the cloud—today’s replacement for the mainframe.
Instead of a single (and secure) mainframe, the cloud today is usually a bunch, maybe hundreds, of small virus-prone personal computers which can be accessed on the Internet. These servers are hooked up together by a network of wires.
The servers (a marketing term) are connected by messages sent over the wires by a relatively inefficient and slow technology called TCP/IP (another great marketing term).
The long-used and alternative to small PC servers, the IBM mainframe, is in a single box and is not slowed down by a jumbled network of external wires. Unlike PC servers, the IBM mainframe has never been subject to viruses, Trojans, mal-ware, and the like.
Those were the days my friend—and they are coming back.
So why aren’t IBM mainframes used by all those brilliant techies out there? Blame it on the educational system which teaches only what the “pundits,” who may lack work experience put into the curriculum.
Fortunately, economics are forcing us forward into the past with cloud computers.
Hopefully, the value of the IBM mainframe will be rediscovered.
