🚀 Self-Hosted VPS Ecosystem

This repository documents a production-ready, self-hosted VPS ecosystem built and managed on a single Linux VPS.
The goal of this project was to learn real-world backend, DevOps, and system deployment by building and running multiple live services end-to-end.

All services are live, secured with HTTPS, auto-restart on reboot, and accessible via custom subdomains.

🧠 Motivation For Building Own Classroom: https://classroom.yashodeep.app

While studying on public platforms like YouTube, distractions significantly reduced focus.
This project was built to create a private, distraction-free learning ecosystem with full control over content, security, and availability.

   └── classroom.yashodeep.app  → Jellyfin Media Server

Each service runs independently and is isolated at the application level.

⚙️ Key Features

• Multiple production services on a single VPS
• Custom subdomains for each service
• HTTPS enabled for all services
• Auto-start on system reboot
• Linux permission and storage management
• Secure VPN access
• Media streaming without third-party platforms
• Private cloud storage with user separation

---

📂 Storage Structure

/srv/
 └── media/
     ├── tutorials/
     ├── coding/
     ├── docs/

All media permissions are managed to allow Jellyfin read/write access.

🔄 Service Reliability

• All services are registered with systemd or Docker restart policies
• Services automatically restart after:
  • VPS reboot
  • Unexpected crashes
• Nginx and SSL certificates renew automatically

---

🔐 Security Practices

• HTTPS on all endpoints
• Reverse proxy isolation
• Private VPN access
• Linux user/group permission control
• Firewall rules to expose only required ports

---

📈 What I Learned
