To define service boundaries with domain-driven design, you map bounded contexts to individual microservices, ensuring each service owns a specific business domain. This approach aligns service boundaries with business capabilities for cross-team collaboration.

The best way to plan monolith decomposition is applying the Strangler Fig pattern to incrementally extract leaf services. This migration planning strategy allows gradual replacement of monolithic components without disrupting the entire distributed system.

You manage distributed transactions in microservices using the Saga pattern, which sequences local transactions with compensating actions. This orchestrates cross-service data consistency without requiring traditional two-phase commits.

You need a service mesh when managing complex microservices requiring standardized observability, resiliency, and inter-service communication. It abstracts cross-cutting concerns away from application code, simplifying orchestration and deployment.

You map bounded contexts by identifying domain boundaries and defining explicit relationships between them, such as shared kernels or customer-supplier models. This clarifies team ownership and service dependencies within the distributed system.

Microservices observability best practices involve implementing centralized logging, distributed tracing, and metrics monitoring to track service health. These patterns ensure resiliency and simplify debugging across complex distributed systems.
