- AI in Education Technology: Server Configuration
This article details the server configuration required to support Artificial Intelligence (AI) applications within an Education Technology (EdTech) environment. It is intended for system administrators and server engineers new to deploying AI-powered EdTech solutions on our MediaWiki platform. We will cover hardware, software, and networking considerations. This assumes a deployment supporting approximately 500 concurrent users. Scaling beyond this will necessitate proportional increases in resources.
Overview
The integration of AI into EdTech is rapidly evolving. Common applications include personalized learning paths, automated grading, intelligent tutoring systems, and predictive analytics for student success. These applications are computationally intensive, requiring robust server infrastructure. Key considerations include processing power (CPU/GPU), memory (RAM), storage (SSD/HDD), and network bandwidth. Proper configuration is crucial for performance, scalability, and reliability. We will focus on a Linux-based server environment, specifically Ubuntu Server 22.04, which is our standard.
Hardware Requirements
The following table outlines the recommended hardware specifications for the primary AI server. A secondary server will be required for database management and a third for load balancing and web services. Details for those are in later sections.
| Component | Specification | Quantity |
|---|---|---|
| CPU | Intel Xeon Gold 6338 (32 cores, 64 threads) | 2 |
| RAM | 256GB DDR4 ECC Registered | 1 |
| GPU | NVIDIA A100 (80GB) | 2 |
| Primary Storage | 2TB NVMe SSD (for OS, applications, and active datasets) | 1 |
| Secondary Storage | 8TB SATA HDD (for archival data and backups) | 2 |
| Network Interface | 10 Gigabit Ethernet | 2 |
| Power Supply | 1600W Redundant | 2 |
Software Stack
The software stack consists of the operating system, AI frameworks, databases, and web server components.
- Operating System: Ubuntu Server 22.04 LTS (Long Term Support). This provides a stable and secure foundation. See Ubuntu Server Installation Guide for details.
- AI Frameworks: TensorFlow 2.x and PyTorch 1.x. These frameworks provide the tools for building and deploying AI models. Installation instructions can be found at TensorFlow Installation and PyTorch Installation.
- Programming Language: Python 3.9 is the primary language for AI development and deployment. See Python 3.9 Setup.
- Database: PostgreSQL 14. This relational database is used to store student data, learning materials, and AI model outputs. Refer to PostgreSQL Configuration.
- Web Server: Nginx. This high-performance web server handles incoming requests and serves the EdTech application. See Nginx Configuration.
- Containerization: Docker and Kubernetes. These tools are used to containerize and orchestrate AI applications, improving portability and scalability. See Docker Basics and Kubernetes Introduction.
Secondary Server Configuration (Database)
The database server handles all data storage and retrieval. It is crucial to ensure data integrity and performance.
| Component | Specification | Quantity |
|---|---|---|
| CPU | Intel Xeon Silver 4310 (12 cores, 24 threads) | 1 |
| RAM | 128GB DDR4 ECC Registered | 1 |
| Storage | 4TB NVMe SSD (RAID 1) | 2 |
| Network Interface | 10 Gigabit Ethernet | 1 |
| Power Supply | 850W Redundant | 1 |
PostgreSQL is the database of choice, configured with appropriate indexing and replication for high availability. See PostgreSQL Replication Guide. Database backups should be performed daily and stored offsite.
Tertiary Server Configuration (Load Balancing & Web Services)
This server distributes traffic across the primary and secondary servers, ensuring high availability and responsiveness.
| Component | Specification | Quantity |
|---|---|---|
| CPU | Intel Xeon E-2336 (8 cores, 16 threads) | 1 |
| RAM | 64GB DDR4 ECC Registered | 1 |
| Storage | 1TB NVMe SSD | 1 |
| Network Interface | 10 Gigabit Ethernet | 2 |
| Power Supply | 650W | 1 |
Nginx is configured as a load balancer using the `upstream` module. SSL/TLS encryption is essential for secure communication. See Nginx Load Balancing and SSL Certificate Installation. This server also handles static content delivery.
Networking Considerations
- Network Topology: A dedicated VLAN should be created for the EdTech environment to isolate traffic and improve security. See VLAN Configuration.
- Firewall: A firewall (e.g., `iptables` or `ufw`) should be configured to restrict access to the servers. See Firewall Setup.
- Bandwidth: Sufficient bandwidth is crucial for handling the volume of data transferred between servers and clients. At least 10 Gbps is recommended.
- Monitoring: Network monitoring tools (e.g., Nagios or Zabbix) should be deployed to track network performance and identify potential bottlenecks. See Network Monitoring Tools.
Security Considerations
- Regular Security Audits: Conduct regular security audits to identify and address vulnerabilities. See Security Audit Procedure.
- Access Control: Implement strict access control policies to limit access to sensitive data and systems. See Access Control List.
- Data Encryption: Encrypt data at rest and in transit to protect against unauthorized access. See Data Encryption Guide.
- Intrusion Detection System: Deploy an intrusion detection system (IDS) to detect and respond to malicious activity. See Intrusion Detection System.
Future Scalability
As the EdTech application grows, it will be necessary to scale the server infrastructure. This can be achieved by:
- Horizontal Scaling: Adding more servers to the cluster.
- Vertical Scaling: Upgrading the hardware of existing servers.
- Cloud Migration: Migrating the application to a cloud platform (e.g., AWS, Azure, or GCP). See Cloud Migration Strategy.
