Snapshots and Cloning

The capability to capture VM snapshots and perform cloning operations provides additional safety nets for operational continuity. Snapshots allow administrators to preserve consistent states of running systems, making recovery from issues a streamlined process. Cloning, on the other hand, facilitates rapid scaling and the deployment of consistent environments for testing or production purposes.

Architecture and Integration

Red Hat OpenShift Virtualization is designed with robust architecture suitable for dynamic hybrid cloud deployments. The virtualization layer is integrated directly into the OpenShift Container Platform, ensuring that both VMs and containers are managed using the same orchestration constructs. The underlying architecture builds on Kubernetes-native elements, extending familiar functionality to cater to virtualization needs.

This deep integration means that system administrators can use established Kubernetes APIs, controllers, and tools to manage VMs. Automation and orchestration extend naturally between both environments, providing cohesive lifecycle management and consistent policy enforcement. Features such as labels, annotations, and selectors that are integral to Kubernetes apply equally to VMs under OpenShift Virtualization, bridging traditional IT operations with cloud-native practices.

Integration with Red Hat Ecosystem

The versatility of OpenShift Virtualization is further enhanced through strategic integrations with other Red Hat products. When combined with Red Hat Ansible Automation Platform, for example, administrators can automate complex tasks such as deployments, configuration management, and scaling. In parallel, integration with Red Hat Advanced Cluster Management offers extended visibility and control over distributed clusters and hybrid cloud environments.

These integrations not only simplify administrative overhead but also contribute to a secure and robust operational framework. By leveraging the combined strengths of various Red Hat solutions, organizations can ensure that their hybrid infrastructure remains scalable, resilient, and aligned with modern IT best practices.

Red Hat OpenShift Virtualization Engine

In addition to the standard virtualization features within OpenShift, Red Hat also offers the OpenShift Virtualization Engine, a specialized edition primarily focused on virtualization workloads. This engine is streamlined by stripping away module features that are not directly related to VM management, providing a cost-efficient and focused solution for organizations with heavy virtualization demands.

The Virtualization Engine is particularly beneficial for scenarios where enterprise requirements are centered solely around VM management rather than a hybrid mix of containerized and virtualized workloads.
