ROSA with HCP instance types - Policies and service definition | Introduction to ROSA

AWS x86-based instance types
AWS Arm-based Graviton instance types

All ROSA with HCP clusters require a minimum of 2 worker nodes. Shutting down the underlying infrastructure through the cloud provider console is not supported and can lead to data loss.

Approximately one vCPU core and 1 GiB of memory are reserved on each worker node and removed from allocatable resources. This reservation of resources is necessary to run processes required by the underlying platform. These processes include system daemons such as udev, kubelet, and container runtime among others. The reserved resources also account for kernel reservations.

OpenShift Container Platform core systems such as audit log aggregation, metrics collection, DNS, image registry, SDN, and others might consume additional allocatable resources to maintain the stability and maintainability of the cluster. The additional resources consumed might vary based on usage.

For additional information, see the Kubernetes documentation.
