High Availability (HA) considerations

IBM Cloud Pak for Watson AIOps

HA configures your deployment with extra replication of its services, and affinity rules to provide redundancy. A HA configuration allows your deployment to tolerate upgrades and service interruptions to a portion of the infrastructure, such as a single node failure.

Sizing is configured in your IBM Cloud Pak for Watson AIOps installation custom resource with the parameter Capacity (Red Hat® OpenShift® Container Platform UI) or spec.size (Red Hat OpenShift CLI), and can be set to small for starter deployments or large for production deployments. For a high availability deployment, you must set a value of large in your IBM Cloud Pak for Watson AIOps Installation custom resource when you create your IBM Cloud Pak for Watson AIOps instance.

For more information about sizing, see Hardware requirements.

A technology preview of installing IBM Cloud Pak for Watson AIOps on a multi-zone architecture is also available. For more information, see Installing IBM Cloud Pak for Watson AIOps on a multi-zone architecture (multi-zone HADR).

Infrastructure Automation

If you are installing Infrastructure Automation for use with IBM Cloud Pak for Watson AIOps, you can help set up high availability for your IBM Cloud Pak for Watson AIOps deployment by selecting a production (large) sizing profile.

If you are installing Infrastructure Automation as a stand-alone deployment and you are using Infrastructure management appliances, you can configure different settings to help you set up high availability. For more information, see High Availability Guide
