🕸️ Advanced Microservices in Go – Mastery Roadmap
This roadmap is designed for developers who already have a good understanding of Go and want to master microservices architecture.
It covers intermediate to advanced concepts, including service design, communication, resilience, DevOps integration, observability, and real-world scaling patterns.
📍 Phase 1: Microservices Fundamentals with Go
🎯 Goal: Understand the microservices mindset and build simple, independent services in Go.
Topics
- Microservices vs Monoliths
- Pros & cons, trade-offs
- When to choose microservices
- Service Design
- Bounded contexts & domain-driven design (DDD)
- Service contracts and APIs
- REST APIs in Go
net/http, gorilla/mux, chi- Middleware design
- JSON & error handling
- Configuration & Environment Management
viper for config- Environment variables & 12-factor principles
Recommended Resources
- Books
- Building Microservices – Sam Newman
- Tutorials
- Practice Projects
- Build a user management service (CRUD + REST)
- Add a configurable logging system
⚡ Phase 2: Service-to-Service Communication
🎯 Goal: Learn inter-service communication patterns and Go tools for APIs and messaging.
Topics
- REST vs gRPC
- Designing APIs with OpenAPI/Swagger
- gRPC + Protocol Buffers in Go
- Messaging
- Async communication with RabbitMQ, NATS, or Kafka
- Event-driven microservices
- Service Discovery
- DNS-based discovery
- Tools: Consul, etcd
Recommended Resources
- Books
- Microservices in Go – Matthew Campbell
- Practice Projects
- Build two services (user + orders) communicating via REST
- Convert the communication to gRPC
- Add event-driven notifications with RabbitMQ
🌐 Phase 3: Resilience, Scaling, and Observability
🎯 Goal: Make microservices production-ready with resiliency patterns and observability.
Topics
- Resilience Patterns
- Circuit breakers (resilience4go, custom)
- Retries, timeouts, backoff strategies
- Bulkheads & rate limiting
- Observability
- Logging (Zap, Logrus)
- Metrics with Prometheus + Grafana
- Distributed tracing with OpenTelemetry + Jaeger
- API Gateways
- Kong, Ambassador, NGINX Ingress
- Authentication & rate limiting
Recommended Resources
- Books
- Release It! – Michael T. Nygard
- Practice Projects
- Add retry + timeout logic to a gRPC service
- Integrate Prometheus metrics & Grafana dashboards
- Implement distributed tracing across 3 services
🏆 Phase 4: Deployment, CI/CD, and Advanced Patterns
🎯 Goal: Learn how to deploy and manage microservices in production.
Topics
- Containers & Orchestration
- Dockerizing Go services
- Kubernetes (Deployments, Services, ConfigMaps, Secrets)
- CI/CD
- GitHub Actions or GitLab CI for pipelines
- Canary deployments & rolling updates
- Advanced Patterns
- Saga pattern for distributed transactions
- Event sourcing + CQRS
- Service mesh (Istio, Linkerd)
Recommended Resources
- Books
- Cloud Native Go – Mina Andrawos
- Practice Projects
- Deploy services to Kubernetes with Helm
- Implement Saga pattern for multi-service transactions
- Add a service mesh for traffic management
💡 General Tips
- Start small: build a few services, then expand.
- Follow 12-factor app principles.
- Write contract tests for service boundaries.
- Automate everything: CI/CD, tests, deployments.
- Observe everything: logs, metrics, traces.
Happy Scaling! 🎉
