Overview and Roadmap Edward Oakes eoakes@anyscale.com

Outline ● Ray Serve Introduction ● Feedback from the Community ● Plans for Ray 2.0 and beyond ○ Preview for other talks today! 2

Native Libraries 3rd Party Libraries universal framework for distributed computing Ray Ecosystem 3

Ray Serve TL;DR Flexible, scalable compute for model serving 1. Scalable 2. Low latency 3. Efficient First-class support for multi-model serving Python-native: mix business logic & ML 4

Multi-model Serving Pattern: multiple models making up a single application 5 Standing Cat

Write a unified Python program Use your favorite tools & libraries Scale across CPUs and GPUs 6 Multi-model Serving

Feedback from the Community Multi-model serving is a big need and key strength 💸💸 💸 ML inference is expensive! Efficiency is key. We need better support & documentation for CI/CD ● Emerging pattern: continual learning 7

In-progress for Ray 2.0 Double down on multi-model: Deployment Graph API 1. REST API & improved Kubernetes support 2. Integrations with best-in-breed MLOps tooling Seamless interoperability with Ray AIR Hear from Jiao later today! 8 Hear from Shreyas later today! 🤩🤩 🤩

Extended Roadmap ● Scale-to-zero ● gRPC support ● Model multiplexing (100s-1000s of small models) ● Shared memory for model weights ● … 9 We want to hear from you!
