Host classes
The host class determines the computing power allocated for each host in the cluster. When you change the host class for a cluster, all existing hosts change to match it.
The available storage doesn't depend on the host class. For storage limitations, see Quotas and limits.
Available host classes
Hosts in Data Proc clusters are deployed on Yandex Compute Cloud VMs. You can create these VMs on any of the platforms that Compute Cloud supports. For a detailed description of the platforms, see Platforms.
The full list of possible host configurations on each platform is provided below.
