New Enterprise Grade Virtualization Capabilities Added in OpenShift 4.16
Unified Disaster Recovery as Part of GitOps
|
Translation in progress...
|
OpenShift now supports synchronous data replication and automated failover between geographically close locations for containers and VMs. Red Hat promises that this new capability covers the vast majority of common VM setups, but admins should still verify the proper replication and failover for their specific workloads.
|
|
OpenShift 4.16 also brings a tech preview of the policy-driven definition and management of disaster recovery via declarative code statements. This enables DevOps teams to define the desired state of the entire cluster of VMs and containers to ensure automated recovery and consistency across regions.

Unified Multi-Cluster VM-Monitoring
|
Translation in progress...
|
Collecting VM metrics and health data from different clusters in different locations and then aggregating them is a key capability required for consistent, and therefore scalable, VM management. This enables the IT team to monitor all VMs across multiple OpenShift clusters from a single dashboard and to centrally resolve issues across all VMs, from one central interface. For example, an admin may be responsible for 50 OpenShift clusters across different regions but will receive a unified dashboard to look at all VMs by health status, resource utilization, or performance, and define alerts depending on these metrics and the type of VMs in question.

Server, Storage, and Network Integration
|
Translation in progress...
|
OpenShift 4.16 adds several key integrations with hardware platforms by vendors like Dell, HPE, Lenovo, and IBM. These integrations enable VMs running on OpenShift to take advantage of these platforms’ specific capabilities like snapshots, cloning, network policies, quality of service controls, and GPU-based AI training and inference. Therefore, these integrations enable enterprises to leverage past investments in specialized hardware and infrastructure, while modernizing applications on a modern Kubernetes-based platform.

One Fish, Two Fish, Redfish
|
Translation in progress...
|
The new Redfish integration is exciting to see as it demonstrates the significant role this standard can finally play when it comes to enabling scalability of cloud-native apps. OpenShift can now evacuate workloads based on Redfish alerting of problems of the underlying server host. It can also update the BIOS, GPUs, network interface cards, and DPUs of hosts to specific versions, attach “data images” to allow OpenShift to update device drivers and manage the BIOS. This simplifies the deployment and management of OpenShift deployments on bare metal (at the edge).

Simplified Migration
|
Translation in progress...
|
Ansible Migration Factory is a reference implementation of how to leverage Ansible Automation Platform for determining the requirements of virtualized workloads and for the subsequent automated VM migration to OpenShift Virtualization. This provides DevOps teams with the ability to consistently onboard VM workloads, based on predefined criteria and with minimal manual effort.
