SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires fastapi, httpx, circuitbreaker, aiokafka, tenacity, and includes references (resource) and assets (resource) components.

What problem does it solve?

This Skill guides you in designing robust microservices architectures, addressing challenges like service decomposition, inter-service communication, distributed data management, and resilience.

Core Features & Use Cases

Service Decomposition: Strategies for breaking down monoliths by business capability or subdomain.
Communication Patterns: Implements synchronous (REST, gRPC) and asynchronous (event-driven) communication.
Distributed Data & Transactions: Manages data ownership and implements the Saga pattern for eventual consistency.
Resilience Patterns: Applies Circuit Breaker, Retry with Backoff, and Bulkhead to prevent cascade failures.
Use Case: Decompose a large monolithic e-commerce application into microservices, ensuring clear service boundaries, event-driven communication for order processing, and resilient inter-service calls.

Quick Start

Explain the "Database Per Service" pattern and its benefits in microservices architecture.

FAQPage Schema

How do I decompose a monolith into microservices?▼

Decompose a monolith by identifying business capabilities or subdomains, then break functionality into independently deployable services with clear boundaries. Assign data ownership to each service, define API contracts for synchronous communication, and use event-driven messaging for asynchronous coordination to minimize coupling.

What's the best way to handle communication between microservices?▼

Use synchronous communication (REST, gRPC) for request-response flows requiring immediate replies, and asynchronous event-driven messaging for workflows where services publish and consume events. Event-driven patterns reduce tight coupling and improve resilience by decoupling service dependencies.

How do I manage distributed transactions across microservices?▼

Implement the Saga pattern to coordinate transactions across multiple services without distributed locks. Sagas break operations into local transactions with compensating actions, achieving eventual consistency while maintaining data integrity across service boundaries.

Why do I need circuit breakers and retry patterns in microservices?▼

Circuit breakers prevent cascade failures by stopping requests to failing services, while retry with backoff and bulkheads isolate faults. These resilience patterns protect distributed systems from cascading outages when services degrade or experience latency.

Can I use the database-per-service pattern with eventual consistency?▼

Yes. Database-per-service enforces service boundaries and data ownership, ensuring each service controls its schema. Pair it with event-driven communication and Saga pattern to achieve eventual consistency across services without shared databases.

What's the difference between API Gateway and direct service-to-service calls?▼

API Gateway provides a single entry point, handles cross-cutting concerns like routing and rate limiting, and shields clients from service topology changes. Direct calls suit internal service communication; gateways suit client-facing APIs and polyglot ecosystems.
