Virtualization infrastructure continues to evolve

For more than 2 decades, organizations have relied on virtualization technologies to deliver innovative applications and services that streamline operations, optimize costs, and promote new business opportunities. The introduction of virtual machines into datacenters helped IT teams efficiently use resources, improve flexibility, and optimize infrastructure performance. As public cloud resources became more accessible, virtualization platforms evolved to make use of the scalability, agility, and potential cost benefits offered by new cloud computing models. 

Now, many organizations are reassessing their virtualization platforms and strategies to ensure they have the right combination of consistency, efficiency, and support for their future operations and cloud-based applications. These organizations want to rapidly migrate to a unified, cost-effective platform that can handle their existing virtual machines while preparing them for IT modernization. Even so, Gartner® expects “despite cloud migration and container adoption, 70% of datacenter x86 workloads will continue to use hypervisor-based virtualization through 2027 (down from approximately 80% in 2020).”1 

Application platforms that combine support for both traditional virtual machines and lightweight technologies like containers are of particular interest for organizations that want to get ahead. Teams can readily migrate their current virtual machines to the new platform and run them alongside container-based applications to take advantage of new approaches to building and deploying applications. At the same time, container orchestration platforms often include tools and automation that help IT teams streamline lifecycle management of their applications across massive hybrid cloud environments. IT teams can deploy and administer all workloads—virtualized or containerized—using common processes and tools while taking advantage of new innovation in monitoring, development and deployment pipelines, GitOps, service meshes, and serverless technologies. As a result, organizations can continue to run the virtualized workloads their business relies on while modernizing their applications and approaches at their own pace.

Gain benefits across your organization

Here are 15 reasons to migrate your traditional virtual machines to Red Hat OpenShift.

1. Move to a stable, supported virtualization platform.

Migrating workloads from traditional to modern virtualization platforms can be complicated. To ensure a smooth and efficient migration process, you need to carefully consider virtual machine compatibility, possible configuration changes, and potential performance optimizations. Additionally, differences in virtualization platform deployment and management processes and tools need to be accounted for in your migration plans, especially when moving between cloud providers. Preemptively validating virtual machine compatibility, using warm migration capabilities, and transitioning multiple virtual machines at once can help you move workloads between virtualization platforms rapidly and with less effort.

The migration toolkit for virtualization simplifies and speeds the process of moving existing virtual machines to OpenShift Virtualization, saving you time and minimizing potential errors. In addition, when combined with Red Hat Ansible® Automation Platform, you can automate the migration of groups of virtual machines and related infrastructure—like networking and storage—at scale and speed.

2. Simplify IT operations with a unified platform.

Managing separate platforms for virtual machines and containers can lead to increased complexity, resource fragmentation, and operational overhead. Unified platforms that streamline infrastructure deployment, management, and monitoring across both virtual machines and containers can help you optimize resource use, eliminate duplicate efforts, and quickly adapt to diverse workloads.

OpenShift Virtualization simplifies operations with a single platform for virtual machines, containers, and bare-metal and serverless workloads. Standardize infrastructure deployment and maintain all workloads using a common, consistent set of established, enterprise tools. You can also streamline Day 2 operations from provisioning to deprovisioning with Ansible Automation Platform.

Plus, you can continue to use your existing infrastructure with Red Hat OpenShift via certified partner integrations.

3. Modernize your applications over time, on your schedule.

While migrating monolithic or n-tier applications on virtual machines to containerized, microservices-based workloads can enhance scalability, improve productivity, and increase agility, it can also require significant investments in time and resources. Combining platforms that support mixed applications—those incorporating a combination of virtual machines, containers, and bare-metal and serverless workloads—with modern application development processes and tools can help you strategically transform your applications on your schedule and according to your unique needs.

With OpenShift Virtualization, you get all of the application modernization features and benefits of Red Hat OpenShift. Integrated tools and capabilities help you build, modernize, and deploy applications that include both virtual machine-and container-based workloads.

4. Operate consistently across hybrid and multicloud environments.

One of the key advantages of adopting hybrid and multicloud environments is flexibility. During application deployment, these environments let you choose between various datacenter and cloud resources to balance scalability, performance, and cost according to your business objectives. Application platforms that run and migrate virtual machine workloads consistently across hybrid and multicloud cloud environments help you simplify application deployment, optimize resource use, and maintain operational consistency.

OpenShift Virtualization supports self-managed physical servers in datacenters, edge environments, and public cloud environments, including Amazon Web Services (AWS), so you can choose the optimal infrastructure for your virtual machines. It is also available as part of Red Hat OpenShift Service on AWS—a fully managed cloud service—to offload ongoing platform management and help you get started in less time.

5. Provide self-service options for deploying virtual machines.

Manually deploying virtual machines is an inefficient, error-prone process that can result in inconsistent configurations, long deployment times, and an increased risk of security vulnerabilities. Self-service capabilities let users rapidly and reliably deploy preapproved, security-compliant virtual machine configurations, when they need them and without opening an IT service ticket.

Following standard Red Hat OpenShift roles, users can create virtual machines in their projects—and then grant access to other project members—to help their entire team quickly get the resources they need. Virtual machine instance types simplify self-service provisioning via predefined operating system images, workload types, and hardware requirements. You can also use templates to deploy virtual machines that require advanced configuration, including virtual appliances.

6. Integrate virtual machines into your development and deployment pipelines.

Using virtual machines in development and deployment pipelines can increase the scalability, consistency, and speed of your application delivery processes. Integrating virtual machines in development pipelines lets you deploy standardized, isolated, and reproducible environments for coding, testing, and debugging to increase consistency across development teams. Using virtual machines in continuous integration/continuous deployment (CI/CD) pipelines provides clean, isolated environments for each stage—from build and test to release and deployment—for controlled, reliable application delivery.

With OpenShift Virtualization, you can create, manage, and run commands in virtual machines within development and CI/CD pipelines based on Red Hat OpenShift Pipelines to streamline infrastructure and application delivery.

7. Take advantage of production-grade virtualization hypervisor technologies.

Hypervisor performance, stability, and security are critical for efficient, dependable virtualization infrastructures. Adopting extensively tested and validated hypervisors that are supported by trusted vendors can help you better manage virtualized workloads at scale and increase reliability across diverse environments.

As the underlying hypervisor for OpenShift Virtualization and Red Hat Enterprise Linux, KVM is a security-focused, high-performance, open source hypervisor. First released in 2007, KVM provides a stable, efficient virtualization foundation for organizations worldwide. Today, Linux virtualization powers critical IT infrastructure for a large number of global financial services firms, airlines, manufacturers, public sector organizations, and telecommunications companies and is a popular choice for public cloud deployments.

8. Boost virtual machine performance.

Speedy recovery times are critical when IT services become unavailable due to hardware failures, power outages, or other issues that result in downtime. When this occurs, the applications running in the virtual machines that were using those services are also unavailable. An application platform that can recover and reboot virtual machines quickly and efficiency is essential for keeping your business up and running at all times.

OpenShift Virtualization exhibits near linear boot times for large numbers of virtual machines, so your critical applications can always be available. Using a large-scale deployment of 100 OpenShift Virtualization nodes capable of accommodating 3,000 virtual machines, Red Hat engineers demonstrated the resiliency and performance of OpenShift Virtualization under conditions typically observed during disaster recovery processes.4

9. Accommodate multiple guest operating systems.

In virtualized environments, support for guest operating systems increases the diversity of workloads, applications, and services you can run on shared physical infrastructure. Compatibility with a wide range of operating systems, advanced security features that isolate guests and hosts, and support from experts with extensive experience simplifies virtualization across varied IT environments. Red Hat tests, certifies, and supports guest operating systems for use with OpenShift Virtualization—including certification for Microsoft Windows guest support through Microsoft’s Server Virtualization Validation Program (SVVP)—to help you create an IT environment that meets your business needs. You can also continue to use common in-guest tools like PowerShell, Ansible, and Puppet with virtual machines running on OpenShift Virtualization.

10. Decrease risk with advanced security features and best practices.

Security vulnerabilities in virtualized environments with shared hardware infrastructure increase the risk of unauthorized access, data breaches, and potential service disruptions. Strong isolation technologies, consistent security policies, and adherence to least privilege principles enhance the overall security of virtual machine workloads. 

OpenShift Virtualization follows the restricted Kubernetes pod security standards profile and runs virtual machine workloads without root privileges, helping you comply with current, industrystandard security practices and protect your organization. Red Hat OpenShift also includes core security features—like access controls, network security, and an enterprise registry with a built-in scanner— to protect your platform from the start.

11. Simplify live migration of virtual machines.

Live migration—moving a running virtual machine to another host without interrupting the workload—is crucial for maintaining continuous operations as infrastructure demands change. A virtualization platform that lets you configure, initiate, monitor, and cancel live migrations across your environment helps balance workloads and avoid downtime during maintenance activities.

OpenShift Virtualization supports complete live migration workflows with a unified management console, configurable policies, virtual machine metrics, and traffic encryption to help you keep your applications running reliably. 

12. Back up and restore virtual machines.

When unexpected events or system disruptions occur, backup and restore capabilities can help you recover virtual machines in less time and ensure continued operations. Creating frequent backups—representations of the state and data of a virtual machine at a specific point in time—provides the information needed to restore existing virtual machines.

OpenShift Virtualization lets you back up virtual machines automatically on demand or on fixed schedules, manage saved images, and restore workloads quickly to minimize the impact of disruptions on your business. Red Hat’s certified partner ecosystem also includes  many third-party products for data storage, backup, and restoration. Using the Red Hat OpenShift Operator Framework, you can interact with many of these products directly from Red Hat OpenShift. For example, you can install and configure Ansible Automation Platform via an operator, and use the platform to automate virtual machine lifecycle management, including backup and restore operations.

13. Scale infrastructure as workloads change.

The dynamic workloads, diverse technologies, and rapid pace of development and deployment associated with modern applications places high demands on IT infrastructure. To ensure optimal performance and resource use, virtualization platforms must dynamically and efficiently scale up and down as workloads change.

Machine management features in OpenShift Virtualization—including autoscaling based on workload policies and machine health checks—help you administer infrastructure with greater flexibility and efficiency to meet modern application demands. 

14. Support a collaborative, open source model.

Open source development models promote collaboration, innovation, and community-driven development to rapidly deliver new, advanced virtualization technologies. With access to stable community innovation, open standards for broad compatibility, and open application programming interfaces (APIs) for flexible integration, open source technologies can help you build efficient virtualized environments across datacenter and cloud infrastructures.

Red Hat OpenShift Virtualization uses the proven KVM hypervisor, a widely adopted and trusted virtualization technology used by leading global companies. KVM provides the underlying virtualization capabilities, while Red Hat OpenShift Virtualization uses KubeVirt, a Cloud Native Computing Foundation (CNCF) project, to extend Red Hat OpenShift and support container-native virtualization. KubeVirt provides a unified development platform where developers can build, modify, and deploy applications residing in both containers and virtual machines in a common, shared environment.

15. Work with our virtualization experts.
