Example text

Internet standards continued to evolve during this period. In the 1980s, the number of small computers exploded with the acceptance of the Personal Computer (PC) by businesses. As CPU speed increased and the cost of system memory and disk storage decreased, it became possible to distribute applications from the mainframe onto the new generation of mini-, and eventually microcomputers. Simultaneous pressures on software engineering and computing infrastructure operations in the 1980s did not result in equal investment to resolve them.

In this use case, SNMP technology is the ideal technology. Enter Two-Tier Client Server and FCAPS The next generation of computing architecture was the interactive 2-tier client server. Here, a dedicated client workstation interacted with a database via discrete transactions (read, write, update). This introduced the concept of user experience where the response time of the requests and responses affected the productivity of the user. As these systems increased in scale, messaging and transaction middleware were introduced to automatically divide or partition the processing load across multiple resources.

Of course, no executive wants to hear that his vision is too ambitious. Simply stating that the goal is a “bridge too far” is not going to be helpful. You have to devise a plan that will let you deliver what is solidly within your current capabilities and still allow for some time and flexibility to achieve the other activities that are not yet within current capabilities. The spectrum of what you have today and what you may reliably implement later breaks down nicely into skills, processes, and competencies, as you will see later.
