Decomposing a monolith into microservices starts by identifying bounded contexts using Domain-Driven Design principles. Map business capabilities to service boundaries, define API contracts for inter-service communication, plan data ownership strategies, and deploy incrementally using Kubernetes or container orchestration to manage scaling and reliability.

Data consistency across microservices relies on the database-per-service pattern combined with consistency mechanisms like Saga for distributed transactions. Design clear data ownership boundaries per service, use asynchronous messaging for eventual consistency, and implement compensation logic to handle failures across service calls.

Microservices communication uses synchronous patterns like REST and gRPC for immediate responses, and asynchronous patterns with message queues for decoupled workflows. Choose based on latency, coupling, and failure tolerance requirements. Define API contracts upfront and use service discovery for dynamic endpoint management in distributed deployments.

Kubernetes is a primary orchestration platform for microservices deployment, scaling, and service discovery. It manages container lifecycle, handles load balancing, enables rolling updates, and automates recovery. Use it to implement deployment strategies and operational governance across distributed services at scale.

Microservices introduce operational complexity, distributed debugging challenges, and data consistency trade-offs. Network latency between services increases, monitoring and testing become harder, and service coordination requires careful API governance. Evaluate monolithic or modular alternatives if your team lacks DevOps maturity or your domain lacks natural service boundaries.

Domain-Driven Design is essential for identifying clean service boundaries and avoiding distributed monoliths. It provides vocabulary for defining bounded contexts—autonomous domains with independent data and logic. Apply DDD to ensure each microservice owns its business capability end-to-end, reducing coupling and enabling independent scaling.
