Model Serving in MLOps is the process of deploying trained machine learning models into production environments where they can receive input data and generate predictions for real-world applications. It enables organizations to make AI models accessible through APIs, cloud platforms, or edge devices while ensuring scalability, reliability, low latency, and efficient resource usage. Effective model serving also includes monitoring, version management, security, and automated scaling to maintain consistent performance over time. In your opinion, what are the most important factors for successful model serving in production, and what challenges do organizations commonly face when managing large-scale AI deployments?
