This project is an implementation of a simplified cloud-based file storage system. It supports secure file uploads and downloads, authentication, and metadata management.
- 🔐 Authentication – Basic user login and token-based authorization.
- 📁 File Upload/Download – REST endpoints for storing and retrieving files.
- 🧾 Metadata Tracking – File metadata stored and queryable (e.g., size, type, owner, timestamp).
- 🔄 Fault Tolerance – Redundancy and recovery strategies using replication.
- 📤 Secure File Sharing – Shareable links or access tokens for shared files.
- Java 24
- Spring Boot (REST APIs, validation, security)
- JUnit & Mockito for testing
- MySQL (for metadata storage)
- Local File System (for simulating storage)
- JWT for authentication
This project was built to deepen understanding of:
- Backend systems architecture
- Designing scalable and testable APIs
- Security and file access control
