Study Notes
Understanding Software Architecture
Software architecture refers to the structured arrangement of components, modules, and subsystems in a software system, which interact and collaborate to ensure the system meets its functional, nonfunctional, and operational requirements. It serves as a blueprint for understanding the behavior and interactions within the system, facilitating effective communication between stakeholders and guiding the development and maintenance of the software product.
Structural Issues and Components of Software Architecture
The structural components of software architecture include the following:
Gross Organization and Global Control Structure
These encompass the overall layout of the system and the division of responsibilities among its components. They help define the primary activities of a system, its functional units, and the flow of information and control within the system.
Protocols for Communication, Synchronization, and Data Access
These determine the rules and conventions for how different components communicate with each other and exchange data. They also establish mechanisms for coordinating activities between components and managing the system's state.
Assignment of Functionality to Design Elements
This involves deciding which tasks are best suited to specific design elements and how those elements will collaborate to accomplish the desired functionality.
Physical Distribution
Physical distribution refers to the geographical placement of system components across hardware devices, networks, or processing nodes, affecting factors like performance and scalability.
Composition of Design Elements
Composition concerns how individual software components are combined and connected to create a larger system with defined interfaces and interaction patterns.
Scaling and Performance
Scaling and performance considerations involve optimizing the system's response times, throughput, and resource utilization in relation to changing demands or growth scenarios.
Selection Among Design Alternatives
Architecture choices require evaluating trade-offs between alternative designs and selecting the optimal one based on a set of criteria relevant to the project's goals and constraints.
Importance of Software Architecture
Software architecture plays a crucial role in achieving key business and technology outcomes, such as agility, efficiency, security, maintainability, and compliance. It enables organizations to adapt to rapidly changing technology landscapes, reduce costs, minimize risks, and deliver value faster.
