Selecting an architectural style requires balancing non-functional needs like scalability, reliability, and performance. You evaluate monolith, microservices, event-driven, and serverless patterns against specific requirements to determine the optimal system structure and boundaries.

Documenting architecture decisions is best done using Architecture Decision Records (ADRs) to capture governance, context, and trade-offs. ADRs provide a structured format to track technology stack selections and enforce best practices across the software development lifecycle.

Planning a migration strategy requires applying patterns like the strangler fig or parallel run to incrementally decompose a monolith. You define domain boundaries, evaluate event-driven integration patterns, and manage data architecture transitions to minimize risk during the migration.

You need Architecture Decision Records whenever making significant technology stack selections or defining system boundaries. ADRs document the trade-off analysis, risk assessment, and governance behind architectural choices, ensuring long-term maintainability and anti-pattern awareness.

Defining service boundaries requires analyzing domain decomposition to delineate microservices based on business capabilities. You evaluate data architecture decisions, such as using event sourcing or CQRS, and establish integration patterns to manage dependencies between the newly defined services.
