Your Roadmap to Mastering Microservices Architecture in

This roadmap will guide you from the basics to advanced concepts of microservices architecture, covering development, deployment, security, and real-world applications.

🗓️ Day 1-10: Getting Started with Microservices

✓ to Microservices: Understand the fundamentals.

✓ Benefits & Drawbacks: A balanced view of microservices.

✓ Development Setup: Prepare your environment.

✓ First Microservice: Build and run your first service.
✓ REST API Fundamentals: Learn to create and consume REST APIs.

You Should Know:

• Basic REST API Commands (cURL):

  curl -X GET https://api.example.com/users 
  curl -X POST -H "Content-Type: application/json" -d '{"name":"John"}' https://api.example.com/users 
  

• Starting a Simple HTTP Server (Python):

  python3 -m http.server 8000 
  

🗓️ Day 11-20: Diving into Containers and APIs

✓ Docker Overview: What is Docker? Why it matters.

✓ Docker Installation: Get Docker running.

✓ Creating a Docker Image: Master container management.

✓ OpenAPI Specification: Learn OpenAPI specs.

You Should Know:

• Basic Docker Commands:

  docker pull nginx 
  docker run -d -p 8080:80 --name mynginx nginx 
  docker ps -a 
  docker build -t myapp . 
  

• Generating OpenAPI Specs (Swagger):

  npm install -g swagger-cli 
  swagger-cli validate api-spec.yaml 
  

🗓️ Day 21-30: Advanced Microservices Concepts

✓ Decomposition Patterns: Domain-Driven Design.

✓ Database Patterns: Database per Service.

✓ Kubernetes : Minikube & Kubernetes basics.

You Should Know:

• Minikube Startup:

  minikube start 
  kubectl get pods 
  

• Deploying a Sample App:

  kubectl create deployment nginx --image=nginx 
  kubectl expose deployment nginx --port=80 --type=NodePort 
  

🗓️ Day 31-40: Kubernetes and Security Essentials

✓ Kubernetes Fundamentals: Pods, Services, Deployments.

✓ Security Essentials: OAuth, RBAC, Input Validation.

You Should Know:

• Kubernetes Security (RBAC):

  kubectl create role developer --verb=get,list --resource=pods 
  kubectl create rolebinding dev-binding --role=developer --user=dev-user 
  

• Input Validation (Python Flask):

  from flask import Flask, request, jsonify 
  app = Flask(<strong>name</strong>) </li>
  </ul>
  
  @app.route('/submit', methods=['POST']) 
  def submit(): 
  data = request.get_json() 
  if not data.get('username'): 
  return jsonify({"error": "Username required"}), 400 
  return jsonify({"success": True}) 
  

  🗓️ Day 41-50: Advanced Security & Resilience

  ✓ Defence-in-Depth & Encryption

  ✓ Resilience Patterns: Circuit Breaker, Retry, Fallback.

  You Should Know:

  • Implementing Circuit Breaker (Resilience4j):

    CircuitBreakerConfig config = CircuitBreakerConfig.custom() 
    .failureRateThreshold(50) 
    .waitDurationInOpenState(Duration.ofMillis(1000)) 
    .build(); 
    CircuitBreaker circuitBreaker = CircuitBreaker.of("myService", config); 
    

  🗓️ Day 51-70: Observability & Deployment Strategies

  ✓ Distributed Tracing (Jaeger/Zipkin)

  ✓ Blue-Green & Canary Deployments

  You Should Know:

  • Jaeger Setup (Docker):

    docker run -d -p 16686:16686 -p 6831:6831/udp jaegertracing/all-in-one 
    

  • Canary Deployment (Kubernetes):

    kubectl set image deployment/myapp myapp=myapp:v2 --record 
    kubectl rollout status deployment/myapp 
    

  🗓️ Day 71-100: Final Project & Real-World Use Cases

  ✓ Build & Deploy a Microservices App

  ✓ Testing & OWASP Top 10 Security

  You Should Know:

  • OWASP Security Scanning (ZAP):

    docker run -v $(pwd):/zap/wrk -t owasp/zap2docker zap-baseline.py -t https://example.com 
    

  What Undercode Say:

  Microservices architecture requires mastering Docker, Kubernetes, API security, and observability tools. Key takeaways:
  – Use `kubectl` for Kubernetes management.
  – Secure APIs with OAuth2 & RBAC.
  – Monitor with Jaeger/Prometheus.
  – Automate deployments with CI/CD pipelines.

  Expected Output:

  A fully functional, secure, and observable microservices application deployed on Kubernetes with automated scaling and resilience.
