• Provide the ability to integrate IBM Cloud Activity Tracker with your cluster to audit the actions that users take in the cluster.

• Set up IBM Cloud Activity Tracker or other capabilities to track user activity in the cluster.

• Maintain controls commensurate to various industry compliance standards, such as PCI DSS. Compliance to industry standards varies depending on the infrastructure provider of the cluster, such as classic or VPC.
• Monitor, isolate, and recover the cluster master.
• Provide highly available replicas of the Kubernetes master API server, etcd, scheduler, and controller manager components to protect against a master outage.
• Provide options for cluster network connectivity, such as public and private cloud service endpoints.
• Provide options for compute isolation, such as dedicated virtual machines or bare metal.
• Integrate Kubernetes role-based access control (RBAC) with IBM Cloud Identity and Access Management (IAM).

• Set up and maintain security and regulation compliance for your apps and data. For example, choose how to set up your classic cluster networking or VPC cluster networking, protect sensitive information such as with IBM Key Protect encryption, and configure further security settings to meet your workload's security and compliance needs. If applicable, configure your firewall.

• Monitor and report the health of the master and worker nodes in the various interfaces.
• Automatically apply master security patch updates, and provide worker node security patch updates.
• Enable certain security settings, such as encrypted disks on worker nodes
• Disable certain insecure actions for worker nodes, such as not permitting users to SSH into the host.
• Encrypt communication between the master and worker nodes with TLS.
• Provide CIS-compliant Linux images for worker node operating systems.
• Continuously monitor master and worker node images to detect vulnerability and security compliance issues.
• Provider-managed encryption is enabled by default on all volumes.

As part of your incident and operations management responsibilities for the worker nodes, apply the provided security patch updates.

• Optionally configure bring your own key encryption for worker node volumes.

• Maintain service availability across worldwide locations so that customers can deploy clusters across zones and regions for higher DR tolerance.
• Provision clusters with three replicas of master components for high availability.
• In multizone regions, automatically spread the master replicas across zones.
• Continuously monitor to work to ensure the reliability and availability of the service environment by site reliability engineers.
• Update and recover operational Red Hat OpenShift on IBM Cloud and Kubernetes components within the cluster, such as the Ingress application load balancer and file storage plug-in.
• Back up and recover data in etcd, such as your Kubernetes workload configuration files
• Provide the ability to integrate with other IBM Cloud services such as storage providers so that data can be backed up and restored.

• Set up and maintain disaster recovery capabilities for your apps and data. For example, to prepare your cluster for HA/DR scenarios, follow the guidance in High availability for Red Hat OpenShift on IBM Cloud. Note that persistent storage of data such as application logs and cluster metrics are not set up by default.

• Provision clusters with Red Hat OpenShift components installed so that you can access the Red Hat OpenShift API to deploy and manage your containerized apps.
• Provide a number of managed add-ons to extend your app's capabilities, such as the Diagnostics and Debug Tool. Maintenance is simplified for you because IBM provides the installation and updates for the managed add-ons.
• Provide cluster integration with select third-party partnership technologies, such as Log Analysis, Monitoring, and Portworx.

• Automatically configure security settings to prevent insecure access, such as disabling SSH into the worker node compute hosts.
• Automatically integrate IBM Cloud IAM service access roles with Kubernetes RBAC roles in the cluster.
• Generate an API key that is used to access infrastructure permissions for each resource group and region.

• Maintain responsibility for your apps, data, and their complete lifecycle.
