Workshop topic:
Microservice Patterns
Time & Date:
October 28 & 29 | 9am-5pm CET
Microservices are a very powerful, yet dangerous architecture. After we clarify the reasons for distributed systems, you will master key techniques for building fault-tolerant systems, best practices and pitfalls of asynchronous communication, event-driven architectures, and techniques for maintaining distributed consistency.
Agenda:
Introduction to Microservices
- Definition and History
- Benefits and Drawbacks
- Organization/Architecture alignment (Conway’s Law)
- Team Topologies Intro
From Monolith to Modulith to Microservices
- Technical vs Domain partitioning
- Module contract
- Module interaction patterns
- Data decoupling, database refactoring
- Extracting a Module as a Microservice
- Exercise: refactoring to decoupled modules
API Design and Management
- REST APIs, Swagger/OpenAPI
- API Semantic Versioning (semver.org)
- Exercise: identify API breaking changes
- API Gateway, BFF Pattern, API Aggregator & Strangler Fig Pattern
- Contract Tests
- Authentication / Authorization Strategies
Patterns for High Availability
- Resilient Deployment Patterns
- Isolation Patterns: Fallback, Retry, Idempotency, Async HTTP
- Latency Control Patterns: Timeout, Throttling, Circuit Breaker, Multiplexing
- Exercise: configure resilience parameters
- Sidecar pattern (Istio)
Message-Based Asynchronous Communication
- Messaging vs RPC (REST)
- Messaging Patterns: DLQ, message priority, correlation-id, claim check
- Commands vs Events (Notifications vs Stateful)
- Choreography vs Orchestration
- Event-Driven Architecture Styles
- Exercise: Select comm: REST, MQ, Event, WebSocket, GraphQL, Event-stream
Maintaining Distributed Consistency
- CAP Theorem and Eventual Consistency
- Inbox and Outbox Pattern, Change Data Capture
- Handling Errors with Compensations, Reservations, and the Saga Pattern
- Exercise: designing a food delivery app
Operating Microservices
- Health Checks
- Centralized logging, Metrics and Request tracing (OTEL)
Testing
- Honeycomb Testing Strategy
- Service Mocks for End-to-end testing
