- AI Model Deployment
Introduction
AI model deployment is the process of taking a trained machine learning model and making it available for real-world use. This is a critical step in the Machine Learning Lifecycle, moving beyond research and development to practical application. Successfully deploying an AI model requires careful consideration of infrastructure, software, and operational procedures. This article details the server configuration aspects of deploying AI models within our MediaWiki environment, focusing on the technical requirements and best practices. The challenges of AI model deployment aren't simply about getting a model to *run*; it's about ensuring it runs reliably, efficiently, and securely at scale. This encompasses elements like model serving, API Gateway configuration, resource allocation, and ongoing monitoring. We’ll cover containerization using Docker, orchestration with Kubernetes, and the importance of selecting the right GPU Architecture for optimal performance. Effective **AI model deployment** necessitates a robust and scalable infrastructure. This article will help you understand those requirements.
Core Components of an AI Deployment Pipeline
A typical AI model deployment pipeline consists of several key components:
- **Model Training:** The process of creating the AI model using various algorithms and datasets. This is often done offline and requires significant computational resources. See Computational Resources for ML for details.
- **Model Packaging:** Converting the trained model into a deployable format, such as a serialized file or a container image. Model Serialization Formats details common approaches.
- **Model Serving:** Hosting the model and making it accessible via an API. This is where the server configuration becomes critical.
- **Monitoring and Logging:** Tracking the model's performance, identifying potential issues, and collecting data for retraining. Monitoring and Alerting Systems are essential here.
- **Scaling:** Adjusting the resources allocated to the model serving infrastructure to handle varying workloads. Horizontal Scaling Techniques are vital for high availability.
- **Version Control:** Managing different versions of the model and the associated code. Git Version Control is standard practice.
