Quick Start

Copy# Invoke microservices skill
"Decompose my monolith into microservices"
"Design API gateway for my services"
"Implement Saga pattern for distributed transactions"

Decomposition Strategies

Service Decomposition Example

CopyE-commerce Monolith → Microservices

├── user-service          # Authentication, profiles
├── product-service       # Catalog, inventory
├── order-service         # Orders, checkout
├── payment-service       # Transactions
├── notification-service  # Email, push, SMS
└── api-gateway           # Routing, auth, rate limiting

Communication Patterns

Synchronous (REST/gRPC)

Copy# Service-to-service call
import httpx

async def get_user_from_user_service(user_id: str):
    async with httpx.AsyncClient() as client:
        response = await client.get(f"http://user-service/users/{user_id}")
        return response.json()

Asynchronous (Events)

Copy# Event publishing
from kafka import KafkaProducer

producer = KafkaProducer(bootstrap_servers=['kafka:9092'])

def publish_order_created(order):
    producer.send('order-events', {
        'type': 'ORDER_CREATED',
        'order_id': order.id,
        'user_id': order.user_id
    })
