Declarative MLOps — Streamlining Model Serving on Kubernetes

Summary

The web content discusses the deployment of machine learning models in production using Kubernetes, emphasizing the benefits of native K8s operators, best practices for containerization, and the integration of CI/CD with GitOps for efficient MLOps.

Abstract

The article titled "Declarative MLOps — Streamlining Model Serving on Kubernetes" outlines an efficient approach to deploying ML models in a Kubernetes environment. It underscores the advantages of using Kubernetes for its scalability and compatibility with MLOps tools, while also addressing potential challenges. The author advocates for leveraging native K8s operators to manage model deployment and highlights three methods of model serving: via HTTP endpoints, message queues, and long-running batch processing tasks. Each method is suited to different scenarios, and the article provides insights into best practices for containerizing ML models, including the creation of custom containers and sanity checks. Furthermore, the piece elaborates on the adoption of Continuous Integration and Continuous Delivery within the MLOps workflow, utilizing tools such as GitHub Actions, Argo CD, and Kustomize to establish a repeatable and scalable deployment process, thereby ensuring rapid and reliable production updates.

Declarative MLOps — Streamlining Model Serving on Kubernetes

Data Scientists often favor Jupyter Notebooks for experimenting with and training ML models. However, deploying these models in production can greatly benefit from a more efficient approach that ensures repeatability, scalability, and swift delivery. Kubernetes offers an ideal environment for this purpose. Although third-party solutions can simplify model serving, this talk aims to clarify the use of native K8s operators for model deployment, along with sharing best practices for containerizing models and implementing CI/CD with GitOps.

In my talk, I discuss how data scientists can leverage Kubernetes (K8s) for deploying machine learning (ML) models in production using native K8s operators. I emphasize the benefits of Kubernetes, such as its scalability and compatibility with most MLOps tools, while also shedding light on the caveats associated with this approach. My goal is to outline methods to effectively deploy and manage ML models in a Kubernetes environment.

I explore three distinct methods for serving ML models: through an HTTP endpoint, a message queue, and long-running tasks for batch processing. Each method has its unique advantages and suits different use cases. Throughout the talk, I delve into containerization best practices for ML models, emphasizing the importance of building custom containers and testing them for sanity.

Additionally, I elaborate on incorporating Continuous Integration (CI) and Continuous Delivery (CD) into the process using GitOps. With the help of tools like GitHub Actions, Argo CD, and Kustomize, I demonstrate how to set up a seamless, repeatable, and scalable ML model deployment process, ensuring high velocity in production.
