What is architectures?

In the context of computer science and engineering, 'architectures' refers to the fundamental structure of a system, be it hardware, software, or a combination of both. It outlines the components, their relationships, and the principles governing their design and evolution. Architectures provide a blueprint for building and maintaining complex systems. Common examples include computer architectures (e.g., x86, ARM), software architectures (e.g., microservices, layered architecture), and enterprise architectures (e.g., defining the IT landscape of an organization). It also includes the overall design of something. For instance, the architecture of a building outlines it's key qualities.
