The Tym Before ...: The Untold Origins of Cloud Computing (Untold Tales of our Digital History),Used

Do you remember Tymnet?If you dont remember, are too young to remember, or fondly remember, this book is for you.This is the story of the worldwide network of online services that existed long before the Internet. Before the modern Cloud there was timesharing. The earliest computers were very expensive, singletask machines devoted to running a single program at a time. Each program loaded from a stack of punch cards, and ran its course without interacting with the outside world. Running payroll, for example, meant that the system was unavailable for any other function until the payroll was complete, the checks printed, the books balanced, and updates written to new punch cards and stored for the next run. This very expensive machine spent most of the time waiting on the peripherals, the printer, the card reader, and the card punch. We called this Batch Processing.Multitasking was a brilliant innovation, allowing multiple programs to run simultaneously, sharing the expensive computing resources across multiple simultaneous batch jobs. Interactive timesharing soon followed, allowing multiple users to interact with the computer in real time using electromechanical Teletype terminals.Then came networks. We know of ARPANET, but have forgotten the others.Several companies arose to offer cloudbased applications available remotely using mechanical terminals, a timeshared computer, and a network. One such company was Tymshare, and the network Tymshare created to deliver remote computer services was Tymnet.Tymnet began operations in late 1968 using a stylized cloud logo that claimed the first Cloud servicesprecursors to todays pervasive cloud infrastructure. Timesharing thus became the first layer of virtualization, and the foundation upon which we built additional layers. Todays sophisticated containerbased virtual services ride upon a timeshared foundation.Teletypes quickly gave way to electronic terminals, and speeds increased rapidly from the 110 bps of the mechanical terminals. In 1972, Tymnet began offering remote, cloudbased applications to companies and institutions worldwide, marking the first truly commercial network. Todays cloud, of course, is far more extensive and varies in the way it allocates virtualized resources among consumers, but the underlying principle is unchanged. We run applications on remote computers and share the physical resources with many others. The differences between todays cloud and that of 1972 are ones of refinement.Tymnet lasted over twenty years, until commercialization of the highly restricted, governmentfunded network playground of the government, military, and academia joined with Tymnet alumni to create the modern Commercial Internet we use today.Read about the earliest computers. Explore the coldwar origins of timesharing and networking. Study the development of commercial, cloudbased network services of the 1960s, 1970s, and 1980s. Read how these services combined with the successors to ARPANET and created the Commercial Internet we use today.Educate yourself on the true history of networking: Buy The Tym Before The Untold Origins of Cloud Computing
