Objective:

To design and implement a scalable and maintainable Learning Management System (LMS) using microservices architecture, where each core functionality (courses, users, assessments, analytics, etc.) runs as an independent service.

Why Choose This Project:

• Improves scalability by allowing each service to scale independently based on demand.

• Facilitates easier maintenance and faster deployment of updates.

• Reduces system downtime since services operate independently.

• Integrates modern software architecture, cloud deployment, and API-driven development, essential skills for enterprise LMS solutions.

Key Features:

Technology Stack:

• Frontend: HTML, CSS, JavaScript, React.js / Angular for web interface.

• Backend:

  • Node.js (Express), Python (Flask / Django), or Spring Boot (Java) for microservices.

  • RESTful APIs or GraphQL for communication.

• Database: Each microservice can use its own database (MySQL, PostgreSQL, MongoDB).

• API Gateway: Kong, NGINX, or AWS API Gateway.

• Service Discovery: Eureka, Consul, or Kubernetes-native service discovery.

• Containerization & Orchestration: Docker + Kubernetes for deploying and scaling microservices.

• CI/CD Tools: Jenkins, GitLab CI/CD, or GitHub Actions.

• Monitoring & Logging: Prometheus, Grafana, ELK Stack (Elasticsearch, Logstash, Kibana).

Working Flow:

1. Client Request

   • Users access LMS via frontend (web or mobile). Requests are routed through the API Gateway.

2. Service Routing

   • API Gateway directs requests to the appropriate microservice (e.g., course service, user service).

3. Service Execution

   • Microservices process the request independently, interacting with their own databases.

4. Inter-Service Communication

   • Microservices communicate using REST APIs or asynchronous messaging (RabbitMQ, Kafka) if needed.

5. Response to Client

   • Results from different services are aggregated and sent back to the client via API Gateway.

6. Scaling & Monitoring

   • Kubernetes scales individual services based on load.

   • Monitoring tools track performance, resource usage, and errors.

Main Modules:

1. User Management Service (registration, authentication, roles)

2. Course Management Service (create, update, delete, view courses)

3. Assessment & Quiz Service (tests, quizzes, assignments)

4. Analytics & Reporting Service (performance dashboards, engagement metrics)

5. Notification Service (emails, messages, alerts)

6. API Gateway & Routing Module

Security Features:

• Role-based access control per service.

• JWT or OAuth 2.0 for authentication and authorization.

• Secure communication between microservices (HTTPS/TLS).

• API rate limiting and throttling.
