# AI in Belfast: Server Configuration
This article details the server configuration supporting the "AI in Belfast" project, providing a technical overview for system administrators and developers. This project focuses on providing accessible AI resources and training within the Belfast community, and requires robust and scalable server infrastructure. This document assumes a basic understanding of Linux server administration and networking concepts.
Overview
The "AI in Belfast" infrastructure consists of three primary server roles: a web server (front-end), an application server (AI model hosting and API), and a database server (metadata and user data). These servers are hosted within a private cloud environment at the Belfast City Hall data center. Redundancy is built in at each layer to ensure high availability. This configuration leverages Debian 11 (Bullseye) as the operating system for all servers. SSH access is strictly controlled using key-based authentication. Firewalls are configured using iptables to restrict incoming and outgoing traffic.
Web Server Configuration
The web server handles all incoming HTTP/HTTPS requests, serving static content and proxying requests to the application server. It's the first point of contact for users.
Software Stack:
- Web Server: Nginx 1.22
- SSL/TLS: Let's Encrypt with Certbot
- Caching: Redis for session management and page caching.
- Reverse proxy configuration directing `/api/*` requests to the application server.
- SSL/TLS configuration for secure communication (HTTPS).
- Caching rules to reduce load on the application server. See Nginx caching documentation for details.
- Logging configured to send access and error logs to a central syslog server.
- Containerization: Docker 20.10
- Orchestration: Docker Compose
- Programming Language: Python 3.9
- AI Frameworks: TensorFlow, PyTorch, scikit-learn
- API Framework: Flask
- Database: PostgreSQL 14
- Backup: pg_dump with regular scheduled backups.
- Monitoring: Prometheus and Grafana for performance monitoring.
- Regular vacuuming and analyzing to maintain database performance.
- Connection pooling to reduce database overhead.
- Strict access control using PostgreSQL roles and permissions. See PostgreSQL documentation for security best practices.
- WAL archiving enabled for point-in-time recovery.
- Regular security audits are conducted.
- All software is kept up-to-date with the latest security patches.
- Intrusion detection and prevention systems (IDS/IPS) are in place.
- Multi-factor authentication (MFA) is required for all administrative access.
- Implementation of a Kubernetes cluster for more sophisticated container orchestration.
- Integration with a cloud-based object storage service for backups and archiving.
- Exploration of serverless computing options for certain application components.

Hardware Specifications:
| CPU | Memory | Storage | Network Interface |
|---|---|---|---|
| 2 x Intel Xeon Silver 4210 | 32 GB DDR4 ECC RAM | 2 x 1 TB NVMe SSD (RAID 1) | 10 Gbps Ethernet |
Nginx Configuration Highlights:
Application Server Configuration
The application server is the core of the "AI in Belfast" project, responsible for hosting the AI models and providing an API for accessing them. It requires significant computational resources. We utilize Docker to containerize the AI models for ease of deployment and scalability.
Software Stack:
Hardware Specifications:
| CPU | Memory | GPU | Storage | Network Interface |
|---|---|---|---|---|
| 2 x AMD EPYC 7763 | 128 GB DDR4 ECC RAM | 2 x NVIDIA A100 80GB GPUs | 4 x 2 TB NVMe SSD (RAID 10) | 25 Gbps Ethernet |
Docker Compose Configuration:
The application server utilizes a `docker-compose.yml` file to define and manage the various AI model containers. Each container is isolated and can be scaled independently. See the Docker Compose documentation for more details.
Database Server Configuration
The database server stores user data, model metadata, and other persistent data required by the "AI in Belfast" project. Data security and integrity are paramount.
Software Stack:
Hardware Specifications:
| CPU | Memory | Storage | Network Interface | RAID Level |
|---|---|---|---|---|
| 2 x Intel Xeon Gold 6248R | 64 GB DDR4 ECC RAM | 4 x 4 TB SAS HDD | 10 Gbps Ethernet | RAID 6 |
PostgreSQL Configuration Highlights:
Networking Configuration
All servers are connected via a private VLAN. A central DNS server manages internal name resolution. A load balancer distributes traffic across the web servers. VPN access is provided for remote administration.
