Arkkitehtuuripäätös

Arkkitehtuuripäätös refers to a decision made within the field of software architecture. It is a fundamental choice about how a system is structured, its components and their relationships, and the principles that guide its design and evolution. These decisions are critical because they impact the system's quality attributes such as performance, scalability, maintainability, security, and cost.

Arkkitehtuuripäätökset are often made early in the development lifecycle and can be difficult and expensive to change later. They are typically informed by a deep understanding of the problem domain, the technical landscape, and the business requirements. The process of making an arkkitehtuuripäätös involves evaluating various architectural styles, patterns, and technologies, considering their trade-offs, and selecting the option that best meets the project's goals.

Common examples of arkkitehtuuripäätökset include choosing between a monolithic architecture and a microservices architecture, deciding on the data storage strategy (e.g., relational database vs. NoSQL), or selecting the communication protocols between different system components. Documenting these decisions and their rationale is a crucial part of good software engineering practice, enabling better communication among the development team and facilitating future modifications and extensions of the system. The impact of an arkkitehtuuripäätös can be long-lasting, shaping the entire trajectory of a software product.
