Ray Clusters Overview
|
|
=====================
|
|
|
|
Ray enables seamless scaling of workloads from a laptop to a large cluster. While Ray
|
|
works out of the box on single machines with just a call to ``ray.init``, to run Ray
|
|
applications on multiple nodes you must first *deploy a Ray cluster*.
|
|
|
|
A Ray cluster is a set of worker nodes connected to a common :ref:`Ray head node <cluster-head-node>`.
|
|
Ray clusters can be fixed-size, or they may :ref:`autoscale up and down <cluster-autoscaler>` according
|
|
to the resources requested by applications running on the cluster.
|
|
|
|
Where can I deploy Ray clusters?
|
|
--------------------------------
|
|
|
|
Ray provides native cluster deployment support on the following technology stacks:
|
|
|
|
* On :ref:`AWS and GCP <cloud-vm-index>`. Community-supported Azure and Aliyun integrations also exist.
|
|
* On :ref:`Kubernetes <kuberay-index>`, via the officially supported KubeRay project.
|
|
|
|
Advanced users may want to :ref:`deploy Ray manually <on-prem>`
|
|
or onto :ref:`platforms not listed here <ref-cluster-setup>`.
