Defining service boundaries for distributed systems requires capturing domain contexts and establishing clear modular interfaces. You separate responsibilities into distinct services to ensure independent deployment, scalability, and resilience across the backend architecture.

Migrating a monolith to distributed backend services requires defining new service boundaries and API contracts before establishing inter-service communications. You refactor existing monolithic structures into modular services with well-defined interfaces and integration patterns.

Planning observability and resilience for distributed systems involves establishing monitoring needs and selecting fault-tolerance patterns during architecture design. You define rollout plans and architecture patterns that ensure backend stability and scalability across inter-service communications.

Yes, you need to define API contracts before building inter-service communications to ensure reliable integration. Establishing service boundaries and contracts early provides a framework for resilient distributed systems and prevents communication failures across microservices.

You should not use microservices architecture when your backend cannot support the overhead of distributed systems and inter-service communications. If domain boundaries are unclear or observability needs are low, a modular monolith may be more appropriate than complex distributed services.
