You gotta love how things in life seem to go in cycles. Bell bottoms are in style in the 70′s – afterwards we spend 20 years+ making fun of them just to have then come back in style.
I have a relative (really smart business guy) who was heavy into IT back in the 80′s who asked me to assist in setting up a client/server application a few years back for his company. They were always in the same office but as they spread their firm out a bit they needed remote access to the application. Going to a web application wasn’t an option due to a large investment in the software and to be honest it was running well except for the remote access part of it.
I decided to just install the application on a server and enable terminal services so that all the employees (even in the same office) would just remote desktop (RDC) into the new server. When my relative asked me to explain what RDC did in simple terms I put it this way to him:
me: remember the days of connecting to a mainframe with a dumb terminal and everything was green and text only?
relative: yes
me: well, imagine that the dumb terminal has a much fatter connection to it and it’s in color, all the screens are transmitted to your end user. That’s all we’ve done here.
relative: got it
So when I think about it, we’ve all gone full cycle on many things. But I remember making fun of mainframes as they are a bit before my time and considered “old school”. Now if you look at these large virtualized blade server farms with all the users connecting via web browser we’ve gone back full circle to centralized computing with a single place where all the security and maintenance takes place. The clients can be somewhat un-secure and all is normally fine since the interaction is purely by browser. So as much as we may be hyping cloud it’s not a ton different that we had in the past with time sharing systems and similar.
