Red Hat OpenShift Service on AWS service definition
This documentation outlines the service definition for the Red Hat OpenShift Service on AWS (ROSA) managed service.
Account management
This section provides information about the service definition for Red Hat OpenShift Service on AWS account management.
Billing and pricing
Red Hat OpenShift Service on AWS is billed directly to your Amazon Web Services (AWS) account. ROSA pricing is consumption based, with annual commitments or three-year commitments for greater discounting. The total cost of ROSA consists of two components:
-
ROSA service fees
-
AWS infrastructure fees
Visit the Red Hat OpenShift Service on AWS Pricing page on the AWS website for more details.
Cluster self-service
Customers can self-service their clusters, including, but not limited to:
-
Create a cluster
-
Delete a cluster
-
Add or remove an identity provider
-
Add or remove a user from an elevated group
-
Configure cluster privacy
-
Add or remove machine pools and configure autoscaling
-
Define upgrade policies
You can perform these self-service tasks using the Red Hat OpenShift Service on AWS (ROSA) CLI, rosa.
Instance types
Single availability zone clusters require a minimum of 3 control plane nodes, 2 infrastructure nodes, and 2 worker nodes deployed to a single availability zone.
Multiple availability zone clusters require a minimum of 3 control plane nodes, 3 infrastructure nodes, and 3 worker nodes. Additional nodes must be purchased in multiples of three to maintain proper node distribution.
Control plane and infrastructure nodes are deployed and managed by Red Hat. Shutting down the underlying infrastructure through the cloud provider console is unsupported and can lead to data loss. There are at least 3 control plane nodes that handle etcd- and API-related workloads. There are at least 2 infrastructure nodes that handle metrics, routing, the web console, and other workloads. You must not run any workloads on the control and infrastructure nodes. Any workloads you intend to run must be deployed on worker nodes. See the Red Hat Operator support section below for more information about Red Hat workloads that must be deployed on worker nodes.
|
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. |
