Meet the Expert: Dean Wampler on Scaling ML/AI Applications with Ray

Topic: Data

Watch the video recording of this event.

Modern ML and AI applications require a lot of compute power, which usually means distribution over a cluster of machines, as well as management of distributed state, such as the model parameters being trained. Ray, a high-performance distributed execution framework developed by UC Berkeley’s RISELab, is targeted at large-scale machine learning and reinforcement learning applications. Ray’s features make it suitable for any Python-based application that needs cluster-wide scalability.

Join us for this edition of Meet the Expert with Dean Wampler to see how Ray meets the needs of ML/AI applications—without requiring the skills and DevOps effort typically required for distributed computing. You’ll learn how Ray enables distribution of Python applications over a cluster and explore examples of ML libraries that use Ray, allowing data scientists to do their work at scale without a lot of programming.

O'Reilly Meet the Expert explores emerging business and technology topics and ideas through a series of one-hour interactive events. You’ll engage in a live conversation with experts, sharing your questions and ideas while hearing their unique perspectives, insights, fears, and predictions.

What you'll learn-and how you can apply it

By the end of this live show, you’ll better understand:

  • The challenges of scaling Python-based applications, especially for ML/AI
  • How Ray makes it much easier to scale these applications
  • How to use Ray-enabled Python libraries for many ML tasks
  • How to use Ray in your own Python applications, such as microservices

This Discussion is for you because...

  • You want to learn about the fundamental architectural shifts in ML/AI and microservices that are hard to satisfy with traditional technologies.
  • You want to learn how to meet those challenges with new systems like Ray.


  • Come with your questions for Dean Wampler
  • Have a pen and paper handy to capture notes, insights, and inspiration
