What Is An Architect?
An architect, in the most common form of the word, is a building or construction architect. They design buildings by defining what it needs to look like and how it needs to be built. This involves:
· Designing a building
· Using standard tools, practices and resources to achieve a result
· Defining what various components are and how they work together
They are involved in the early stages of a building's construction, both in working out what the customer wants and how it can be developed. They don't actually do any of the building or construction work themselves - that's left to other professionals in the building industry (I'm far from an expert in the building industry, so this may seem like an overly simplified example of these jobs).
What Is an IT/Information Technology Architect?
We've established what a building architect is. So, what is IT architecture? We can use the same points to define what an IT architect is.
Designing A System Or Set Of Systems
Instead of deigning a building, an IT architect is involved in the design phase of a system or a set of systems. They will need to know what a system is required to do, what is involved in providing that system, what business process or problem is involved, and how it links to other systems.
In many cases, an IT architect or system architect will need to have a broad view of a company's IT infrastructure or requirements. They will need to know the most effective way of providing an IT solution that meets the company's requirements, budget and other constraints.
Using Standard Tools, Practices And Resources To Achieve A Result
This part of an architect's role is similar to a building architect. The use of standard tools for designing systems is recommended, due to widely accepted best practices and efficiency benefits. While a builder may have standards for their drawing labels, symbols, rules and regulations they need to follow, an IT architect or system architect has similar standards.
Standards exist for diagram symbols, methods and types. A common standard is the Unified Modelling Language, otherwise known as UML. UML is a large language for diagramming and includes a lot of areas of system design, many of which are relevant to the design part of a system architect's role.
Defining Various Components And How They Work Together
The systems or software that the IT architect or system architect defines need to include details about various components and how they work together. This could be at a high level - involving many systems around the department or company, or at a lower level - involving a particular system that includes many linked components. There are many reasons these need to be defined:
· To confirm the current and proposed definitions of a set of systems or a single system, between the architect, the technical teams, the users, and any management teams involved.
· To describe the details of linked systems or system components for various technical teams. Different teams may be responsible for different areas of a system or different systems altogether. Communication between these components is common, and someone needs to define and document them. This is where the IT architect comes in.
