As part of my journey in backend development, I built a complete infrastructure using Docker and Docker Compose. The goal was to simulate a real-world production environment with multiple services working together.
Architecture
This project is composed of several services:
- Nginx → Reverse proxy & web server
- MariaDB → Database
- Redis → Caching system
- FTP Server → File management
- Adminer → Database interface
- Portainer → Container management
Each service runs in its own container, ensuring isolation and scalability.
Why Docker?
Docker allows:
- Isolation between services
- Easy debugging (if one service fails, others stay running)
- Reproducible environments
- Scalability for future improvements
Challenges I Faced
- Configuring Nginx to handle multiple services
- Managing environment variables securely
- Connecting containers via Docker networks
- Optimizing performance under load
What I Learned
- How reverse proxies work (Nginx)
- Managing multi-container applications
- Basics of system design
- Debugging distributed systems
Testing & Performance
I tested the system by simulating multiple requests and checking how the server behaves under load.
Key point:
Each worker in Nginx can handle multiple connections, but bad configuration can lead to bottlenecks.
Conclusion
This project helped me understand how real backend systems are structured and deployed. It’s a big step toward building scalable and production-ready applications.
