Model Serving and Deployment

1. Introduction

Model serving and deployment refer to the processes involved in making machine learning models available for use in production environments. This lesson will cover the key concepts, deployment processes, and best practices essential for effective model serving.

2. Key Concepts

3. Deployment Process

The deployment process can be broken down into several key steps:

1. Model Training: Train the model using your dataset.
2. Model Serialization: Save the trained model to a file format suitable for serving (e.g., TensorFlow SavedModel, ONNX, etc.).
3. API Development: Develop an API using frameworks like Flask, FastAPI, or Django to serve the model.
4. Containerization: Use Docker to containerize your application for easy deployment across different environments.
5. Deployment: Deploy the containerized model to a cloud service (e.g., AWS, GCP, Azure) or on-premises infrastructure.
6. Monitoring: Implement logging and monitoring to track model performance and ensure reliability.

4. Best Practices

• Use version control for your models and APIs to manage changes effectively.
• Automate the deployment process using CI/CD pipelines.
• Implement robust error handling and logging to troubleshoot issues quickly.
• Ensure security measures are in place, including authentication and authorization for API endpoints.
• Regularly update the model with new data to maintain accuracy and relevance.
