Course Description

This comprehensive course is designed to teach you how to build RESTful Microservices using Node.js and Express, while integrating with various databases like PostgreSQL, MongoDB, MySQL, and leveraging message brokers such as Kafka, RabbitMQ, and caching systems like Redis. You'll also learn how to implement best practices in microservice architecture, including unit testing, integration testing, containerization (Docker), orchestration (Kubernetes), and CI/CD pipelines.

The course will walk you through the entire lifecycle of microservices development, from designing scalable APIs to deploying them in production environments. By the end of this course, you’ll have a deep understanding of microservices architecture and the tools necessary to build robust, scalable, and maintainable applications.

Why Learn Building Microservices?

1. Scalability: Microservices allow you to scale individual components of your application independently, which is essential for handling high traffic and complex systems.
2. Flexibility: Each service can be developed, deployed, and maintained independently, allowing teams to work on different parts of the system without affecting others.
3. Technology Agnostic: Microservices enable you to use different technologies (databases, languages, frameworks) for different services, giving you the flexibility to choose the best tool for each job.
4. Fault Isolation: If one service fails, it doesn’t bring down the entire system. This makes microservices more resilient compared to monolithic architectures.
5. Industry Demand: Microservices are widely adopted by tech giants like Netflix, Amazon, and Uber. Learning microservices will make you highly valuable in the job market.
6. DevOps and Cloud-Native: Microservices align well with modern DevOps practices and cloud-native technologies, making them ideal for containerized environments like Docker and Kubernetes.

What You Will Learn:

1. Microservices Fundamentals:

   • Understanding the principles of microservices architecture.
   • Comparison between monolithic and microservices architectures.
   • Benefits and challenges of microservices.

2. Building RESTful APIs with Node.js and Express:

   • Creating scalable and maintainable RESTful APIs.
   • Handling HTTP requests, responses, and routing.
   • Middleware usage for authentication, logging, and error handling.

3. Database Integration:

   • Working with relational databases like PostgreSQL and MySQL.
   • Using NoSQL databases like MongoDB for unstructured data.
   • Implementing database migrations and ORM (Object-Relational Mapping) techniques.

4. Message Brokers and Event-Driven Architecture:

   • Using Kafka and RabbitMQ for asynchronous communication between services.
   • Implementing event-driven architecture for decoupled services.
   • Understanding pub/sub models and message queues.

5. Caching with Redis:

   • Implementing caching strategies to improve performance.
   • Using Redis for session management, rate limiting, and data caching.

6. Testing Microservices:

   • Writing unit tests and integration tests for microservices.
   • Using testing frameworks like Jest and Mocha.
   • Mocking external dependencies and testing API endpoints.

7. Containerization and Orchestration:

   • Containerizing microservices using Docker.
   • Deploying and managing containers with Kubernetes.
   • Setting up CI/CD pipelines for automated testing and deployment.

8. Security Best Practices:

   • Implementing authentication and authorization using JWT (JSON Web Tokens).
   • Securing APIs with HTTPS and OAuth2.
   • Handling sensitive data securely.

9. Monitoring and Logging:

   • Setting up monitoring tools like Prometheus and Grafana.
   • Centralized logging with ELK Stack (Elasticsearch, Logstash, Kibana).
   • Implementing health checks and alerts for microservices.

10. Service Discovery and Load Balancing:

    • Using tools like Consul or Eureka for service discovery.
    • Implementing load balancing with Nginx or HAProxy.
