Five critical views of architecture
There are five critical views, as shown in the following diagram:
Each view focuses on a different aspect of the largest-scale optimization concerns of the system:
- Subsystem/Component Architecture is about identifying subsystems, allocating responsibilities to the subsystems, and specifying their interfaces.
- Distribution Architecture chooses how distributed parts of the system interact, including middleware and communication protocols. This includes, but is not limited to, the network architecture.
- Concurrency and Resource Architecture details sets of concurrency regions (threads and processes), how semantic elements map into those concurrency regions, how they are scheduled, and how they effectively share and manage shared resources.
- Dependability Architecture refers to large-scale design decisions that govern the ability of stakeholders to depend...
