Here are a few quick facts about mainframes, from the recent upsurge in mainframe training to the critical role of terminal emulation in the modern mainframe environment.
These days, we take the simplicity of working with computers for granted. If you're like most people, you're reading this page from a computer running a Windows operating system, though if you fall outside of the majority, it could be the increasingly popular Mac OS X from Apple, or maybe even a PC running Linux. Whatever the case, your operating system is doing an impeccable job of making using your computer a breeze and this is largely thanks to its graphical user interface or GUI. Once upon a time, there were no GUIs -- there were only text based terminals. In this article, we'll take a look at the evolution of computer access from crude terminals to graphical user interfaces, as well as looking at the role that terminal emulation plays today.
Since the arrival of cloud computing, the debate has raged: is cloud computing really just the mainframe re-imagined? Or are the differences significant enough that these two technologies should be considered opposite? In this article, we'll take a look at both the similarities and differences of mainframe and cloud computing technology, including scalability, security, and terminal emulation considerations.
