IIUC Anyscale is managed Ray, and also works on Ray full-time. However Ray is open source and you can run it yourself. It's fairly easy to get started with, too.
This is all open source Ray. None of the AWS benchmarks were run on Anyscale platform. You can install and run OSS Ray on any of the popular clouds, including your laptop.
Founder of Anyscale is the Berkeley student who helped start Ray and is usually happy to give free advice. Anyscale is to Ray as Databricks is to Spark.
you can set up a self-hosted Ray infra to achieve this.
