🌩️ Cloud Storage Project

📚 Overview

Welcome to the Cloud Storage Project! This system offering a robust solution for storing and managing files across multiple nodes.

✨ Features

  • File Storage: Files are stored across multiple storage nodes for redundancy, scalability, and fault tolerance.
  • Load Balancing: Efficiently distributes client requests across available storage nodes to ensure optimal performance.
  • User Authentication: Secure authentication mechanism before performing any file operations.
  • File Operations: Supports UPLOAD, DOWNLOAD, LIST, and DELETE commands.
  • Service Registry: Manages and tracks the status of all registered nodes (both storage nodes and load balancers).
  • Heartbeat Monitoring: Continuously checks the health of storage nodes to ensure system reliability.

🛠️ Technologies Used

  • Java: Core programming language for the project.
  • TCP/IP: Network protocol for communication between nodes.
  • MongoDB: Used for storing metadata and managing user and file information.
  • Maven: Build automation tool for Java projects.
