To break down a monolith, you apply business capability and subdomain-based service decomposition strategies to define independent service boundaries. This skill guides you through planning the transition, establishing communication patterns, and managing data per service.

The Saga pattern is a sequence of local transactions where each updates the database and publishes an event to trigger the next step. This skill details how to implement Sagas for managing distributed transactions across microservices without relying on two-phase commits.

A circuit breaker stops calls to a failing service to prevent cascading failures and allow it to recover. This skill provides implementation guidance for applying circuit breakers, retries, and bulkheads to build resilient, fault-tolerant microservices architectures.

Event-driven architecture is ideal for asynchronous communication when you need to decouple services and improve scalability. This skill helps you determine when to use event-driven models versus synchronous REST or gRPC for inter-service communication.

Yes, this skill directly supports designing e-commerce platforms by breaking down monolithic applications into independent, scalable microservices. It provides use cases like architecting an order management system using service decomposition and resilience patterns.

Database-per-service is a data management pattern where each microservice owns its private database to ensure loose coupling. This skill covers when to implement this pattern alongside distributed transaction strategies like Sagas for data consistency.
