To document cross-service architecture decisions and write ADRs, define and validate major choices using architectural decision records. This ensures consistent service boundaries and principled decisions across multi-service platforms by documenting context, trade-offs, and governance templates.

The best way to plan a service migration is to apply strangler and dual-write/read patterns during the evolution process. This allows gradual migration across services while validating non-functional requirements and maintaining cross-service boundary contracts.

To define and enforce non-functional requirements across multiple services, establish NFR targets and validate trade-offs using a capacity model. This includes cost and security modeling to ensure architecture decisions meet performance and reliability goals.

Yes, you can use C4-lite diagrams for architectural modeling and design reviews. The approach includes C4-lite diagrams and reference templates to document context, containers, and critical paths during cross-service architecture reviews.

To frame cross-service boundaries and define contracts between services, establish clear interfaces and contracts within the architecture context. This ensures consistent integration across multi-service platforms and supports principled ADR-driven decision making.

You need a capacity model when validating architecture trade-offs to quantify cost and security implications against non-functional requirements. This modeling ensures major architectural decisions are validated with concrete data rather than assumptions.
