While terminal emulation inherently is a remote process, accessing a server or mainframe from a terminal with physical distance between the server or mainframe, remote terminal emulation is a relatively new development. Remote terminal emulation, like that offered by Rocket Software, allows the end-user to access a server from outside of the network itself, thus adding an entirely new dimension for users to work under. Employing remote terminal emulation in the workplace can expand capabilities and ease of access for users and administrators.
How it Works
Remote terminal emulation works by changing where the physical terminal emulation client is stored and accessed. Rather than a program that is downloaded onto a computer, the terminal emulation is instead accessed through a browser via an HTML or Java client (depending on the emulator). After running through a series of authentication processes, the terminal emulation establishes a connection between the end-user’s device and the server through a third party web server.
This connection allows the user to access an emulation on any device running on nearly any operating system as long as an internet connection is established and the browser is up to date. Once this is done, remote terminal emulation gives the user a wide range of versatility.
Regarding Security and Safety.
Because a device might not be subject to the same security protocols and standards when operating outside of the server’s network, additional security measures have been taken to make sure that remote terminal emulation is safe (assuming, of course, that the terminal emulation comes from a trusted source). If a user decides to access the server remotely through a terminal emulation, they should of course exercise general caution and common sense. Even if the connection between the emulation and the mainframe might be secure, the device itself might be susceptible to viruses or malware that would could expose vital information to a hacker. Users must establish their physical connection in a safe and controlled environment with adequate measures taken for security.
What Can be Done with Remote Terminal Emulation
Remote terminal emulation allows for a number of interesting and productive possibilities for users. The obvious option of utilization is to access a mainframe without physically being connected to the network, therefore allowing access from home or on the road. However, remote terminal emulation also allows for emulation to take place on a mobile device such as a smartphone or a tablet.
Because the emulation runs through a browser, the device itself does not necessarily need to be a stationary computer or a laptop. Thus, using terminal emulation on an iPad, for example, can allow a user to move about a building and work without the need to carry a bulky laptop. This can be helpful if a user needs to migrate from building to building on a company’s campus. Alternatively, if the user needs to diagnose a problem within a specific location but must be able to travel throughout the area, such as in a server room or on an office floor, remote terminal emulation allows for this. Most terminal emulation programs provided by reliable companies now allow for remote terminal emulation in some way. They can be customized to function and mimic other emulations as well, so if integrated into a company, the learning curve is generally quite small.
