1# Microservices Patterns
2 
3Master microservices architecture patterns including service boundaries, inter-service communication, data management, and resilience patterns for building distributed systems.
4 
5## When to Use This Skill
6 
7- Decomposing monoliths into microservices
8- Designing service boundaries and contracts
9- Implementing inter-service communication
10- Managing distributed data and transactions
11- Building resilient distributed systems
12- Implementing service discovery and load balancing
13- Designing event-driven architectures
14 
15## Core Concepts
16 
17### 1. Service Decomposition Strategies
18 
19**By Business Capability**
20 
21- Organize services around business functions
22- Each service owns its domain
23- Example: OrderService, PaymentService, InventoryService
24 
25**By Subdomain (DDD)**
26 
27- Core domain, supporting subdomains
28- Bounded contexts map to services
29- Clear ownership and responsibility
30 
31**Strangler Fig Pattern**
32 
33- Gradually extract from monolith
34- New functionality as microservices
35- Proxy routes to old/new systems
36 
37### 2. Communication Patterns
38 
39**Synchronous (Request/Response)**
40 
41- REST APIs
42- gRPC
43- GraphQL
44 
45**Asynchronous (Events/Messages)**
46 
47- Event streaming (Kafka)
48- Message queues (RabbitMQ, SQS)
49- Pub/Sub patterns
50 
51### 3. Data Management
52 
53**Database Per Service**
54 
55- Each service owns its data
56- No shared databases
57- Loose coupling
58 
59**Saga Pattern**
60 
61- Distributed transactions
62- Compensating actions
63- Eventual consistency
64 
65### 4. Resilience Patterns
