The Beginning
Having started life as a computer programmer, I’ve since been an IT Manager, an IT Director, and an IT Strategist. It’s unlikely that I’ll be in ‘IT’ much longer. Something new has arrived, and IT just got replaced.
I’ve seen IT develop from the start. Before Information Technology, we had Data Processing. It was very monolithic, and the role of the human ‘operator’ was to feed the computer with the information it needed to process and complete its task. If they had had fingers and eyes, the human part would not have been required.
The PC revolution changed all that. With the arrival of productivity apps, such as Word and Excel (especially Excel), the concept of a ‘User’ replaced that of an operator. The fact that these new PC users could manipulate data to create ‘Information’ is, in my humble opinion, the point where our beloved Information Technology (IT) era started, and it has created countless careers to date.
These careers have evolved as IT has evolved. Initially, IT teams had to manage the growing estate of PCs. Then they invented servers, and so had to manage a growing estate of these. Then along came virtualisation, so their careers moved to making their physical servers disappear inside the virtual imagination of various hypervisors. Next came the Cloud, and IT teams had to learn the language and practices of SaaS, IaaS, DaaS, Baas, and many other cloud hosted services.
