# Machine Learning Operations Server Configuration

This article details the recommended server configuration for running Machine Learning Operations (MLOps) within our MediaWiki environment. It's geared towards system administrators and engineers responsible for deploying and maintaining the infrastructure supporting our machine learning workflows. This covers hardware, software, and networking considerations.

Overview

MLOps requires significant computational resources, especially for training and serving models. This guide outlines the specifications for three primary server roles: the Development Server, the Training Server, and the Inference Server. Each role has different requirements, and proper configuration is crucial for performance, scalability, and reliability. Understanding Resource allocation is paramount. We will also cover Monitoring and logging best practices.

Development Server Configuration

The Development Server is used by data scientists for prototyping, experimentation, and initial model development. It doesn't require the same level of horsepower as the Training or Inference Servers, but it needs sufficient resources to handle common development tasks. Consider using Docker containers for consistent environments.

Component Specification
CPU Intel Xeon Silver 4310 (12 cores, 2.1 GHz) or equivalent AMD EPYC
RAM 64 GB DDR4 ECC
Storage 1 TB NVMe SSD (for OS, code, and datasets) + 4 TB HDD (for backups)
GPU NVIDIA GeForce RTX 3070 (8GB VRAM) – optional, for GPU-accelerated development
Operating System Ubuntu 22.04 LTS
Networking 1 Gbps Ethernet

Software installed on the Development Server should include: Python 3.9, Jupyter Notebook, TensorFlow, PyTorch, scikit-learn, and version control systems like Git. Proper security hardening is essential, even in a development environment.

Training Server Configuration

The Training Server is responsible for the computationally intensive task of training machine learning models. It requires powerful CPUs, a large amount of RAM, and, crucially, multiple high-end GPUs. Distributed training is a common strategy to accelerate training. We utilize Kubernetes for orchestration of these servers.

Component Specification
CPU 2 x Intel Xeon Gold 6338 (32 cores, 2.0 GHz) or equivalent AMD EPYC
RAM 256 GB DDR4 ECC
Storage 2 TB NVMe SSD (for OS and code) + 20 TB RAID 0 SSD (for datasets)
GPU 4 x NVIDIA A100 (80GB VRAM each) with NVLink
Operating System CentOS 8 Stream
Networking 10 Gbps Ethernet (RDMA capable)

The Training Server software stack should include the same components as the Development Server, but with optimized libraries for distributed training (e.g., Horovod, DeepSpeed). Consider using GPU monitoring tools to track utilization and performance. Regular data backups are vital.

Inference Server Configuration

The Inference Server is responsible for deploying trained models and serving predictions in real-time. It needs to be optimized for low latency and high throughput. Model serving frameworks like TensorFlow Serving or TorchServe are recommended.

Component Specification
CPU Intel Xeon Gold 5318Y (24 cores, 2.1 GHz) or equivalent AMD EPYC
RAM 128 GB DDR4 ECC
Storage 1 TB NVMe SSD (for OS, code, and models)
GPU 2 x NVIDIA T4 (16GB VRAM each)
Operating System Ubuntu 22.04 LTS
Networking 10 Gbps Ethernet

The Inference Server should be configured with a load balancer (e.g., HAProxy, Nginx) to distribute traffic across multiple instances for high availability and scalability. API monitoring is crucial to ensure predictions are being served correctly and efficiently. We also employ autoscaling to dynamically adjust the number of inference servers based on demand. Careful capacity planning is essential to meet peak loads.

Networking Considerations

All servers should be connected to a high-bandwidth, low-latency network. Consider using a dedicated VLAN for MLOps traffic. Implement appropriate firewall rules to secure the servers. Network segmentation is a key security practice.
