Ray Serve on Kubernetes – Simplify Your AI ML Deployment Workflow
From Dev to Prod: Discover how Ray Serve’s latest features and native Kubernetes integration revolutionize ML model deployment.
Welcome to the world of MLOps, specially in the context of handling your ML AI workloads on Kubernetes environment. In this article, we will explore how Ray Serve, a flexible, scalable, and efficient compute engine for online inference, can be seamlessly integrated with Kubernetes, providing a powerful tool for deploying and managing machine learning models in production environments.
What is Ray Serve?
Ray Serve is a cutting-edge compute engine designed for online inference tasks. Built on top of the Ray framework, it offers superior scalability, low latency, and efficiency. The platform provides first-class support for multi-model inference, allowing you to combine multiple models to serve complex requests effectively. Notably, Ray Serve is Python-native, offering a simple API to easily integrate arbitrary business logic with model inference.
New Features in Ray Serve 2.0:
Ray Serve 2.0 introduces several features that make it production-ready and enhance the development workflow:
1. Centralized Config Management: In Ray Serve 1.0, configuration information was defined in Python using decorators. However, Ray Serve 2.0 introduces a new approach by consolidating all configuration data into a single YAML file. This centralization streamlines development and ensures a smooth Dev to Prod workflow.
2. Serve CLI: The new Serve CLI in Ray Serve 2.0 simplifies the process of iterating and deploying your applications. It allows you to quickly develop and test your application locally and then deploy it to production seamlessly.
3. Native Kubernetes Integration: One of the most significant enhancements in Ray Serve 2.0 is its native integration with Kubernetes. This integration offers the benefits of Ray Serve, such as the simple API, efficient compute, and scalability, while leveraging Kubernetes’ cluster management features. The result is enhanced observability, blue-green deployments, zero downtime upgrades, and more.
MLOps and Dev to Prod Workflow:
MLOps, short for Machine Learning Operations, involves the practices of deploying, managing, and monitoring machine learning models in production environments. MLOps tools aid in model serving, training, data preparation, validation, and more. MLOps brings several key benefits, including improving the Dev to Prod workflow, streamlining CI/CD pipelines, and providing an ecosystem of support infrastructure tailored to specific applications.
Ray Serve’s Dev to Prod Workflow:
Ray Serve’s new depth to prod workflow in version 2.0 greatly enhances your application’s operational efficiency. It enables developers to:
1. Develop the Application: During development, developers can make quick updates and iterate using the Python API in Ray Serve.
2. Build the Config File: Once the application is ready, the “serve build” command generates a centralized YAML config file containing all the necessary information.
3. Deploy to Production: With the config file in hand, the “serve deploy” command deploys the application to the production Ray cluster.
4. Issue Updates: After deployment, developers can monitor user traffic and make updates to the config file as needed. Ray Serve automatically manages scaling and updates for the deployments.
Native Kubernetes Integration with Ray Serve:
Ray Serve’s native integration with Kubernetes offers a powerful combination of features. The Ray Serve Kubernetes Operator handles the deployment and management of Ray Serve applications on Kubernetes. It provides the following capabilities:
1. Kubernetes Native Logging: Use “kubectl logs” and “kubectl describe” commands to access detailed logs and events for your Ray Serve deployments.
2. Auto Scaling: Ray Serve Auto Scaler interacts with Kubernetes Auto Scaler to manage the scaling of deployments based on incoming requests and available resources.
3. High Availability: The Ray Serve Kubernetes Operator ensures high availability by leveraging Kubernetes recovery mechanisms and monitoring application health.
