AI Services

AI Services Server Configuration

This document details the server configuration for the AI Services suite, providing a guide for new system administrators and engineers deploying and maintaining these crucial components. The AI Services provide backend processing for various features across the wiki, including [Semantic MediaWiki] enhancements, [abuse filtering], and [content translation]. Understanding the underlying infrastructure is key to optimal performance and stability. This configuration is current as of MediaWiki 1.40.

Overview

The AI Services are hosted on a dedicated cluster of servers, separated from the core wiki infrastructure to isolate resource contention. This cluster utilizes a combination of high-performance CPUs, substantial RAM, and fast storage to handle the computationally intensive tasks associated with AI processing. The services themselves are containerized using [Docker] and orchestrated with [Kubernetes] for scalability and resilience. Monitoring is carried out via [Prometheus] and visualized using [Grafana]. Access to the AI Services cluster is restricted to authorized personnel only, utilizing [SSH keys] and multi-factor authentication. Regular [backups] are performed to ensure data recovery in case of failure. All services are designed to be stateless, allowing for easy scaling and replacement of individual instances.

Hardware Specifications

The AI Services cluster consists of five dedicated servers, each with the following specifications:

Component Specification
CPU 2 x Intel Xeon Gold 6248R (24 cores/48 threads per CPU)
RAM 256 GB DDR4 ECC Registered 2933MHz
Storage 2 x 4TB NVMe SSD (RAID 1) for OS and application data
Network 2 x 100 Gigabit Ethernet
Power Supply 2 x 1600W Redundant Power Supplies

These specifications are chosen to provide sufficient processing power and memory for the AI models used. The NVMe SSDs ensure fast data access, critical for minimizing latency. The redundant power supplies offer high availability. [Network configuration] is handled by our dedicated networking team.

Software Stack

The software stack is built around a core of Linux, Docker, and Kubernetes. Here's a breakdown:

Software Version
Operating System Ubuntu Server 22.04 LTS
Containerization Docker 20.10
Orchestration Kubernetes 1.25
Monitoring Prometheus 2.40, Grafana 9.0
Logging Elasticsearch 8.5, Logstash 8.5, Kibana 8.5 (the [ELK stack])
Programming Languages Python 3.9, C++

This stack allows for efficient deployment, scaling, and monitoring of the AI Services. The ELK stack provides centralized logging for troubleshooting and auditing. [Security updates] are applied regularly to all components.

Service Breakdown

The AI Services cluster hosts several key services, each responsible for a specific AI-powered feature.

Service Name Description Scalability
Semantic Analysis Service Processes text to extract meaning and relationships for [Semantic MediaWiki]. Horizontal (up to 10 replicas)
Abuse Filter Service Evaluates edits against predefined rules to detect and prevent vandalism and spam. Horizontal (up to 5 replicas)
Content Translation Service Provides machine translation capabilities for [Translation extensions]. Horizontal (up to 8 replicas)
Sentiment Analysis Service Analyzes the sentiment of text content to identify potentially problematic contributions. Horizontal (up to 3 replicas)
Image Recognition Service Identifies objects and content within uploaded images, used for [category suggestions]. Horizontal (up to 4 replicas)

Each service is deployed as a separate Kubernetes deployment, allowing for independent scaling and updates. [Resource limits] are configured for each service to prevent resource exhaustion. [Load balancing] is handled by Kubernetes services.

Access and Security

Access to the AI Services cluster is strictly controlled. Only authorized personnel with approved [SSH keys] and enabled [multi-factor authentication] are granted access. Network access is limited to specific IP ranges. All communication between services is encrypted using [TLS]. Regular security audits are conducted to identify and address potential vulnerabilities. [Firewall rules] are configured to restrict inbound and outbound traffic.

Future Considerations

Future enhancements to the AI Services infrastructure include:

⚠️ *Note: All benchmark scores are approximate and may vary based on configuration. Server availability subject to stock.* ⚠️
