Understanding IT Architecture
Let’s take a step back and ensure that we fully understand IT architecture within an organization. IT architecture is defined by Gartner as:
”A framework and set of guidelines to build new systems. IT architecture is a series of principles, guidelines, or rules used by an enterprise to direct the process of acquiring, building, modifying, and interfacing IT resources throughout the enterprise. These resources can include equipment, software, communications, development methodologies, modeling tools, and organizational structures.”
