Five key use cases for enterprise virtualization

Last Updated:


Combining traditional virtualization with cloud- and container-based architectures can help you meet these changing requirements. 

Virtualization is a foundational component in modern datacenters and serves as the underlying infrastructure for traditional, cloud-native, and container-based workloads. In fact, more than 80% of datacenter workloads are virtualized today, according to IDC. Through virtualization, you can improve efficiency, free up resources, boost performance, enhance security, and cut costs. 

Red Hat provides agile, fast, and cost-effective virtualization that helps you overcome today’s challenges while building a foundation for future technologies. 


Red Hat® Virtualization is a complete infrastructure solution for virtualized servers and technical workstations. It is easy to deploy and use, allowing you to get started quickly. High-value, economical subscription pricing saves costs and provides faster return on investment (ROI). Support for up to 480 logical CPUs and 6TB of memory per virtual machine (VM) ensures your applications perform as well in a virtualized environment as they do on bare-metal infrastructure. Built-in Red Hat Secure Virtualization (sVirt) and Security-Enhanced Linux® (SELinux) safeguard your virtualized environment. Open, standards-based features and interoperability protect your existing investments and let you customize your infrastructure. Finally, integration throughout the Red Hat software stack provides increased performance, security, and value when you add other products like Red Hat Enterprise Linux, Red Hat OpenStack® Platform, and Red Hat OpenShift Container Platform. 

Virtualization can help IT organizations better support their business in many ways. Here are five common use cases, their benefits, and how Red Hat Virtualization works to provide those benefits more effectively. 


Growing demand, changing business requirements, and new technologies can quickly cause IT infrastructure to become complex. In these complicated environments, server and VM sprawl often leads to inefficiencies. Physical servers are typically overprovisioned to ensure availability during peak demand times. Unused VMs may not be retired due to lack of visibility or ineffective infrastructure management. In both cases, utilization can be low, resulting in higher costs and larger-than-needed infrastructure footprints. 

Proprietary operating systems and virtualization platforms can add to these challenges. Using multiple, disparate management tools can impede visibility into your environment, increase the risk of inconsistencies, and take more time and resources to operate. Proprietary licenses can be expensive and often include features and functionality that you may not need, but still must pay for. Closed interfaces limit your flexibility by preventing you from choosing from the full breadth of complementary technologies to adapt to changing business needs. 

Consolidating physical servers and proprietary virtualization platforms onto a high-performance, reliable, and open virtualization platform—like Red Hat Virtualization—can unify workload and server management, reduce licensing costs, and deliver technology choice. 

When planning for server consolidation, look for a high-performance virtualization platform based on open, standards-based technology that is interoperable with other operating systems and virtualization platforms. Red Hat Virtualization delivers a low total cost of ownership (TCO), faster ROI, and accelerated break-even costs for server consolidation.


With Red Hat Virtualization, you can achieve consolidation ratios of 10 to 1 and reduce server rackspace by up to 75%. Exceptional workload density is provided by bare-metal performance and support for up to 288 logical CPUs and 12TB per host and 240 vCPU and 6TB RAM per VM guest. High-availability features, like live migration and prioritized restarts, ensure reliability for critical workloads. Plus, support for third-party tools lets you choose the right backup, restore, and replication products for your organization’s disaster recovery needs. 


Red Hat Virtualization centralizes management of virtualized compute, network, and storage resources, greatly simplifying operations. A user portal provides standard- and power-user access to the virtualized environment for easier administration and control. Additionally, automated workload management processes and scaling speeds server deployment, configuration, and management. 


With an open source virtualization platform, you can decrease costs and eliminate vendor lock-in. Based on the open source Kernel-based Virtual Machine (KVM), Red Hat Virtualization is intensely tested and commercially hardened for production use. Open and RESTful application programming interfaces (APIs) and certification for Microsoft Windows provides cross-platform interoperability. Furthermore, your subscription includes enterprise-grade support, updates, and patches so you can keep your environment up to date and running at all times.


Many core and critical business workloads have elevated performance and availability requirements. To continuously meet these needs, IT organizations frequently deploy sensitive workloads on segregated infrastructure. To ensure performance during peaks in demand, resources are overprovisioned. Redundant infrastructure is deployed to cope with potential failures. Finally, scaling out requires new servers and resources to be purchased, configured, and managed. All of this adds up to higher costs and operational inefficiencies. 

Virtualizing these workloads can improve their performance and availability. A shared, high-performance virtualized environment eliminates redundancies, increases utilization, and scales easily. Additionally, you can optimize workload placement at deployment and move them as needs change. When migrating performance-sensitive workloads, search for a virtualization platform that delivers leading performance, availability, and scalability. Red Hat Virtualization supplies unmatched scale and performance for enterprise workloads, including SAP® and Oracle, on x86 and Power®


Workloads virtualized with Red Hat Virtualization experience performance on par with bare-metal systems—Red Hat Virtualization holds leading SPECvirt_sc2013 results. In testing, enterprise workloads like SAP, Oracle, and Microsoft Exchange showed performance gains of up to 140%. Several features—like high input/output (I/O) throughput, Kernel SamePage Merging (KSM) memory overcommitment, non-uniform memory access (NUMA), single-root I/O virtualization (SR-IOV), and virtual function I/O (VFIO) support—further enhance performance for virtualized workloads.


Red Hat Virtualization includes several features to ensure availability for virtualized workloads. Live migration and prioritized VM restart capabilities let you seamlessly move VMs from one host to another in case of failure—without downtime. Support for third-party backup, restore, and replication tools lets you use the products that work best for your organization now and in the future. 


Designed for large-scale operations, Red Hat Virtualization supports more than 500 virtual hosts and 5,000 VMs in one environment, allowing you to scale out easily and cost-effectively. Support for hundreds of logical and virtual CPUs and terabytes of memory increases workload density and virtualization efficiency. Hot plug capabilities let you expand compute, memory, disk, and network resources for any workload without restarting its VM. 


Adding Red Hat CloudForms® to your Red Hat Virtualization environment lets you strategically place and move VMs to maximize resource utilization and performance. Integration with the oVirt optimizer provides better optimization logic for managing clusters and placing workloads. You can also define affinity and anti-affinity workload groups to pin workloads with specialized hardware or licensing requirements to specific hosts.


Development and test (dev/test) environments are critical for creating and improving applications and services. However, unoptimized infrastructure can slow delivery of resources to developers, delaying the entire development cycle. As a result, end users may enlist unsanctioned public cloud resources to accomplish their work. These shadow IT resources are outside of IT’s control, increasing the risk of costly security and compliance issues. 

Optimizing your IT infrastructure can help you deliver resources faster. You can increase the efficiency and utilization of resources, provide self-service portals for developers, track and control dev/test environment costs, and bring resources back into IT control.

When optimizing dev/test environments, find a virtualization platform that provides self-service portals for developers, streamlined resource provisioning and management, and visibility into resource use. Red Hat Virtualization provides a simple, inexpensive self-service infrastructure for enterprise development environments. 


Combined with Red Hat CloudForms and Red Hat Ansible® Automation, Red Hat Virtualization speeds resource delivery through centralized and automated resource management. Developers can use a single self-service catalog to request compute, network, and storage resources, simplifying the request process and reducing the number of portals they need to use. Automated provisioning accelerates delivery and ensures that resources are configured in compliance with policies. 


Red Hat Virtualization gives you tools to reduce the cost of nonproduction environments. Quota definition and enforcement limits the number of virtual guests, quantity of storage used, CPU utilizations, and amount of memory on host servers that users can allocate. Detailed reporting and chargeback functionality give you visibility into use and let you allocate costs to user groups. Automated management streamlines resource administration and operations costs. 


With increased speed and visibility, Red Hat Virtualization lets you build a security-focused, nondisruptive, ring-fenced environment to reduce the risks associated with unsanctioned resource use. A system dashboard provides detailed information and a global-use overview of CPUs, memory, and storage host resources. Simple Network Management Protocol (SNMP) support allows you to integrate third-party monitoring systems for increased visibility into your environment. 


Hybrid and bimodal IT approaches are becoming more common as organizations seek to gain the speed, flexibility, and cost benefits of cloud and container technologies. However, putting these concepts into practice can be challenging. Virtualization can play a key role in moving to bimodal operations and building a hybrid environment. This approach allows you to optimize traditional applications and workloads and create a path to private cloud. 

Additionally, many organizations are adopting a multi-hypervisor approach to lower costs and reduce dependence on a single vendor. Adding a second, open source virtualization hypervisor can help you achieve both. Today, 26% of organizations have already deployed more than one hypervisor platform and another 23% have plans to deploy a second hypervisor in the future. Most organizations deploy new workloads on the new hypervisor, but migrating workloads from an existing hypervisor to a new one can be challenging. VMs must first be converted to the new hypervisor format. Then, the contents of the VM—drivers and agents, for example—must be modified. Finally, VMs must be retested and retooled for the new hypervisor and its underlying systems. 

When adopting a multi-hypervisor or hybrid environment, select a virtualization platform that integrates with cloud and container platforms and is interoperable with other hypervisors. Open APIs and workload migration tooling are also essential for smooth transitions. Red Hat Virtualization can help you build a foundation for seamless private and open hybrid cloud implementations.


With high performance and low TCO, Red Hat Virtualization is an ideal choice for organizations that want to reduce dependence on a single hypervisor vendor. Virtual-to-virtual (V2V) conversion tooling lets you migrate workloads from VMware vSphere and vCenter with one click, drastically simplifying transfers. Open, RESTful APIs provide interoperability with both Red Hat and custom-developed tools so you can align your environment with your organization’s needs.
