This document outlines the comprehensive technical architecture for a robust, scalable, and secure application platform. The design encompasses front-end and back-end services, data management, infrastructure, and operational considerations, aiming to provide a clear blueprint for development and deployment. The proposed architecture leverages a microservices paradigm, cloud-native services, and Infrastructure-as-Code (IaC) principles to ensure agility, resilience, and cost-efficiency.
The core objectives of this architecture are:
The system employs a multi-tiered, cloud-native architecture, separating concerns into distinct layers: Client, Edge/API Gateway, Backend Microservices, and Data/Asynchronous Processing.

This document outlines the comprehensive technical architecture for a scalable, secure, and high-performance Online Learning Platform. This architecture is designed to support a rich user experience for learners and instructors, facilitate efficient content delivery, and provide robust administrative capabilities.
This document details the technical architecture for a modern Online Learning Platform, designed to be cloud-native, microservices-based, and highly scalable. The platform will enable users to create, manage, and consume educational content, facilitating a seamless learning experience. Key architectural components include a decoupled frontend, a suite of backend microservices, robust data storage solutions, a resilient infrastructure plan, and comprehensive strategies for scalability, security, and monitoring. This design emphasizes maintainability, extensibility, and operational efficiency.
The primary goal is to build a highly available, performant, and secure online learning platform that can:
The system is broadly divided into three main layers: Presentation, Application (Services), and Data.

Additional components like CDN, Monitoring, CI/CD, and IaC are implicitly part of the overall infrastructure.
* Technology: React with Next.js (for SSR/SSG and SEO benefits).
* Purpose: Course browsing, enrollment, content consumption (video player, quizzes), progress tracking, profile management, payment initiation.
* Deployment: Static assets served via CDN (AWS CloudFront).
* Technology: React with Next.js.
* Purpose: Course creation and management, content upload, student management, performance tracking, earnings reports.
* Deployment: Static assets served via CDN.
* Technology: React with Next.js.
* Purpose: User management, course moderation, platform settings, global analytics, system monitoring.
* Deployment: Static assets served via CDN.
* Technology: React Native or native iOS/Android.
* Purpose: Complement web experience with mobile-specific features (e.g., offline viewing).
All microservices will be containerized using Docker and orchestrated by Kubernetes (AWS EKS). They will communicate primarily via RESTful APIs and asynchronously via an event bus.
* Technology: AWS API Gateway / Nginx / Spring Cloud Gateway.
* Purpose: Single entry point for all client requests, request routing to appropriate microservices, authentication/authorization enforcement, rate limiting, caching, SSL termination.
* Responsibilities: User registration, login, profile management, role-based access control (RBAC), authentication (JWT token generation/validation), password management.
* Data Store: PostgreSQL (for user credentials, profile data, roles).
* Responsibilities: CRUD operations for courses, modules, lessons, quizzes, assignments. Content metadata management.
* Data Store: PostgreSQL (for course structure, metadata).
* Responsibilities: Securely store and stream video/audio content, serve lesson text, images, and other static assets. Integrates with CDN. Handles content encoding/transcoding.
* Data Store: AWS S3 (for raw content), DynamoDB (for content metadata, access controls).
* Responsibilities: Managing student enrollments in courses, tracking progress, completion status, managing certificates.
* Data Store: PostgreSQL.
* Responsibilities: Integration with third-party payment gateways (e.g., Stripe, PayPal), managing subscriptions, processing one-time payments, handling refunds.
* Data Store: PostgreSQL (for transaction records).
* Responsibilities: Sending emails (e.g., welcome, course updates), SMS messages, in-app notifications. Consumes events from other services (e.g., CourseEnrolledEvent, LessonCompletedEvent).
* Technology: AWS SES/SNS, external notification providers.
* Responsibilities: Collects and processes user activity data (e.g., lesson views, quiz scores, time spent), generates reports and dashboards for instructors and admins.
* Data Store: AWS DynamoDB / Elasticsearch (for large-scale event data).
* Responsibilities: Provides full-text search capabilities for courses, instructors, and content.
* Technology: Elasticsearch.
* Data Source: Synchronizes data from Course Management and User Management services via event streams.
* Purpose: Stores structured, transactional data with strong consistency requirements (e.g., User profiles, Course metadata, Enrollments, Payments, Order history).
* Configuration: Multi-AZ deployment for high availability, read replicas for scaling read operations.
* Purpose: Stores semi-structured or unstructured data with high throughput and low latency requirements (e.g., Content access logs, User activity streams, Session data, Content metadata for fast lookup).
* Purpose: Stores all static assets, media files (videos, images, PDFs), course materials. Highly durable and scalable.
* Configuration: Integrated with AWS CloudFront for global content delivery.
* Purpose: Caches frequently accessed data (e.g., popular course listings, user session data, API responses) to reduce database load and improve response times.
* Purpose: Powers the full-text search capabilities across courses, content, and users.
* Purpose: Enables asynchronous, event-driven communication between microservices. Decouples services, handles spikes in traffic, and ensures reliable message delivery.
* Kafka: For high-throughput, ordered event streams (e.g., analytics events, data synchronization).
* SQS/SNS: For simpler message queuing and pub/sub patterns.
