The Untold Origins of Cloud Computing

The Cloud has become ubiquitous.  Long before today’s Cloud, though, another name was used when accessing someone else’s computer: time sharing.  Born in the Cold War in the aftermath of the first Russian Atomic bomb, time-shared computers and networking appeared in the 1960s, became widespread in the 1970s and matured in the 1980s.

Tymshare was an early time-sharing pioneer, deploying Tymnet as the first independent Cloud-based services network in early 1972 by way of a database running on an IBM 360 at the National Library of Medicine.  From that humble beginning, Tymnet grew into a world-wide business-focused public data network, connecting remote terminal users to distant computer users for a wide range of computer applications.  As the business model shifted from connecting a user to a computer to connecting together computers, though, Tymnet’s failure to adapt made it fall victim to the Internet.

Based on his book The Tym Before … The Untold Origins of Cloud Computing, Nathan Gregory will tell the story not only of Tymnet and Tymshare, but also of the development of the ARPANET into today’s Internet.  Copies of the book will be available for sale, and there will be an author signing.
