Installing on a hybrid architecture

Edit online

Use these instructions to prepare and install a hybrid deployment, which is composed of cloud native Netcool® Operations Insight® components on Red Hat® OpenShift®, and an on-premises Operations Management installation.

When you install cloud native Netcool Operations Insight components on Red Hat OpenShift, all of the components are automatically deployed as pods running within the cluster. The deployment of pods across worker nodes is managed by Red Hat OpenShift. Pods for a service are deployed on nodes that meet a services's specification and affinity rules, and are orchestrated by Kubernetes.

The hybrid deployment configuration leverages the power of Netcool Operations Insight's cloud native components, without the need to deploy the full Netcool Operations Insight on Red Hat OpenShift solution. You can deploy only the cloud native Netcool Operations Insight components from the Netcool Operations Insight package on Red Hat OpenShift, and connect them to an on-premises Operations Management installation. The cloud native Netcool Operations Insight components provide cloud native event analytics, cloud native event integrations, runbook automations, and optionally topology management. The on-premises Operations Management installation provides the ObjectServer and Web GUI(s).

The hybrid solution can be deployed in high availability (HA) mode, or non-HA mode.

HA mode: A HA hybrid deployment is composed of cloud native Netcool Operations Insight components on Red Hat OpenShift and an on-premises Operations Management installation that has multiple WebGUI instances to provide redundancy.

The advanced.antiAffinity parameter is set to false by default. To prevent primary and backup server pods from being installed on the same worker node, set this option to true. When enabled, anti-affinity is configured for preferredDuringSchedulingIgnoredDuringExecution. For more information, see Installation properties common to both a Cloud and a Hybrid installation.
Additional deployment steps, which are tagged with the icon, are required for a HA hybrid deployment:
Non-HA mode: A non-HA hybrid deployment is composed of cloud native Netcool Operations Insight components on Red Hat OpenShift and an on-premises Operations Management installation that has only one Web GUI. For a non-HA hybrid deployment, ignore the steps tagged with the icon.

Note: Integration with on-premises IBM Agile Service Manager is not supported for hybrid deployments.
