microservices

Decompose a monolith by applying bounded contexts and the strangler pattern to define service boundaries, improving modularity and scalability. Start practically by splitting a monolith into two services and wiring them through a lightweight API gateway.

You need a saga pattern in distributed systems when implementing reliable event-driven workflows across services with per-service database ownership. Sagas coordinate distributed transactions and maintain data consistency without a shared database.

Implement resilience patterns like circuit breakers, retries, and bulkheads for microservices to handle inter-service communication failures. These patterns prevent cascading failures and ensure reliable workflows across distributed services.

Yes, you can use CQRS with per-service database ownership to separate read and write models within a service. This pattern enables optimized query handling and supports event-driven collaboration while maintaining strict service boundaries.

Yes, you need an API gateway for microservices architecture to route requests, aggregate data, and set up BFF guidance. It provides a unified entry point for clients while maintaining independent service boundaries and per-service data ownership.
