What did you base your architecture design on?

When designing architecture, I usually consider several key factors:

• Functional and non-functional requirements — what the system should do, performance, scalability, security constraints.
• Load and scalability assessment — number of users, data volume, peak loads.
• Technology stack and team experience — choice of tools, languages, and frameworks familiar to the team.
• Maintainability and extensibility — how easy it is to make changes and add new features.
• Integration with existing systems — the need to interact with other services or databases.
• Budget and deadlines — resources available for development and support.

For example, when designing a web application, I might choose a microservices architecture if high load and independent component scaling are expected, or a monolith if the project is small and rapid development is important.
