AI in Kiribati
- AI in Kiribati: A Server Configuration Overview
This article details the server configuration designed to support Artificial Intelligence (AI) initiatives within Kiribati. Due to the unique infrastructural challenges faced by Kiribati, this setup prioritizes efficiency, resilience, and cost-effectiveness. This guide is aimed at newcomers to the server administration aspects of this project.
Background
Kiribati, a nation comprised of 33 atolls and reef islands, faces significant hurdles in deploying and maintaining advanced technologies like AI. Limited bandwidth, unreliable power, and a geographically dispersed population necessitate a carefully considered server infrastructure. This deployment focuses on providing foundational AI capabilities for applications in climate change monitoring, resource management, and healthcare. The initial focus is on edge computing, reducing reliance on constant high-bandwidth connectivity. We will also explore the central server setup in Tarawa. See also Disaster Recovery Planning for related considerations.
Core Infrastructure Components
The system comprises three primary tiers: Edge Nodes, a Central Server in Tarawa, and a Backup/Redundancy site in Fiji. This distribution allows for localized processing and data storage while maintaining a centralized control point. The Fiji site provides disaster recovery and handles larger, less time-sensitive data processing tasks. Understanding Network Topology is crucial.
Edge Nodes
These are low-power, ruggedized servers deployed on select islands. They perform initial data processing, filtering, and basic AI tasks. Each node runs a lightweight Linux distribution (Debian) and utilizes a dedicated solid-state drive (SSD) for storage. Refer to the Linux Server Administration guide for more details.
| Edge Node Specification | Value |
|---|---|
| Processor | Intel Celeron J4125 (4 Cores, 4 Threads) |
| RAM | 8GB DDR4 2400MHz |
| Storage | 256GB NVMe SSD |
| Network | Gigabit Ethernet, 4G LTE (with satellite fallback) |
| Power Supply | 12V DC, Solar/Battery Backup |
| Operating System | Debian 11 (Bullseye) |
Central Server (Tarawa)
Located in a secure facility in Tarawa, the central server handles more complex AI models, data aggregation from edge nodes, and model training. This server is equipped with GPUs for accelerated processing. See GPU Server Management for detailed information.
| Central Server Specification | Value |
|---|---|
| Processor | Dual Intel Xeon Silver 4310 (12 Cores/24 Threads each) |
| RAM | 64GB DDR4 3200MHz ECC |
| Storage | 2 x 2TB NVMe SSD (RAID 1) + 8 x 8TB SATA HDD (RAID 6) |
| GPU | 2 x NVIDIA GeForce RTX 3090 (24GB VRAM each) |
| Network | 10 Gigabit Ethernet, Redundant Internet Connections |
| Power Supply | Redundant 1000W 80+ Platinum PSUs |
| Operating System | Ubuntu Server 22.04 LTS |
Backup/Redundancy Server (Fiji)
This server mirrors the central server's capabilities and serves as a disaster recovery site. Data replication is performed asynchronously to minimize latency. Consult Data Backup and Replication for further details.
| Fiji Backup Server Specification | Value |
|---|---|
| Processor | Dual Intel Xeon Silver 4310 (12 Cores/24 Threads each) |
| RAM | 64GB DDR4 3200MHz ECC |
| Storage | 2 x 2TB NVMe SSD (RAID 1) + 8 x 8TB SATA HDD (RAID 6) |
| GPU | 1 x NVIDIA GeForce RTX 3090 (24GB VRAM) |
| Network | 10 Gigabit Ethernet, High-Bandwidth Internet Connection |
| Power Supply | Redundant 1000W 80+ Platinum PSUs |
| Operating System | Ubuntu Server 22.04 LTS |
Software Stack
The software stack is designed for flexibility and scalability.
- **Operating System:** Ubuntu Server 22.04 LTS (Central & Fiji), Debian 11 (Bullseye) (Edge Nodes)
- **Containerization:** Docker and Kubernetes are used for application deployment and management. See Docker Containerization and Kubernetes Orchestration.
- **AI Frameworks:** TensorFlow and PyTorch are the primary AI frameworks.
- **Database:** PostgreSQL is used for data storage and management. Refer to PostgreSQL Database Administration.
- **Message Queue:** RabbitMQ is used for asynchronous communication between components.
- **Monitoring:** Prometheus and Grafana are used for system monitoring and alerting. See System Monitoring with Prometheus.
Network Configuration
Due to the limited and often unreliable internet connectivity in Kiribati, a mesh network is utilized between the islands with Edge Nodes. This network uses directional antennas and long-range Wi-Fi to provide connectivity where traditional internet access is unavailable. The central server in Tarawa acts as the hub for this mesh network. Network Security Protocols are essential.
Security Considerations
Security is paramount. All servers are protected by firewalls and intrusion detection systems. Regular security audits are conducted. Data encryption is used both in transit and at rest. See Server Security Best Practices.
Future Expansion
Future expansion plans include deploying more edge nodes, upgrading the central server's GPU capabilities, and exploring the use of federated learning to improve model accuracy while minimizing data transfer. We also plan to integrate with the National Data Repository.
