Red Hat Virtualization vs Vmware Vsphere: A Comparison

Last Updated:

RED HAT VIRTUALIZATION 

Red Hat® Virtualization is an open, easy to use, efficient infrastructure and centralized management platform for virtualized Linux® and Windows workloads. Built on Red Hat Enterprise Linux and Kernel-based Virtual Machine (KVM) technologies, it allows customers to virtualize traditional applications and build a foundation for cloud-native and container-based workloads. 

Red Hat Virtualization offers a high-performance, highly available platform with built-in security for business-critical workloads, providing a stable, scalable infrastructure. Offering integrated management with a self-service user portal, Red Hat Virtualization helps customers increase efficiency through consolidation and provides predictable, virtual infrastructure value and costs. 

This document compares the technical features and pricing of Red Hat Virtualization 4.1 and VMware vSphere 6. It is not an exhaustive list for either product, but it explains features that are asked about most frequently. 

VALUE OF A SUBSCRIPTION 

A subscription to Red Hat Virtualization, or any Red Hat solution, goes beyond gaining access to the software. Red Hat’s stable code is backed by a dedicated team of engineers who monitor, identify, and address risks to protect your data—and your customers’ data—from meaningful security concerns. If you need to open a support case, it will be routed to a product specialist. Resolutions enable future updates to our products, making you an active participant in improving open source technology. In addition, Red Hat publishes thousands of solutions in our community-driven Knowledgebase so you can learn from others, resolve issues yourself, and proactively manage your systems. 

Benefits of a subscription include: 

  • Technology—Security, stability, and reliability 
  • Assurance—Enterprise-grade certainty
  • Expertise—Experience you can trust

PRICING MODEL 

When comparing Red Hat Virtualization to VMware vSphere, Red Hat Virtualization offers a number of benefits, as detailed in Figure 1, including: 

  • Significantly lower total cost of ownership (TCO). 
  • No capital expenses (CapEx). 
  • Operating expenses (OpEx) charged via subscription—VMware charges via support. 
  • Subscription sold per socket pair—VMware licenses are sold per single socket. 
  • No extra charges for management. 


On top of VMware’s higher cost, customers also have to purchase licenses and subscriptions for operating systems. Red Hat provides you with the support you need at a much lower cost than what you would pay to get both the product and support from VMware.

KEY DIFFERENTIATORS 
LOWER TCO

Compared with other leading virtualization solutions, Red Hat Virtualization delivers a lower TCO year over year, helping to reduce OpEx budget pressure and concerns. 

TCO results

• 103% return on investment (ROI) 
• US $447,665 net present value (NPV) 
• 5.6 months payback period

IMPROVED SECURITYRed Hat Virtualization includes sVirt and Security-Enhanced Linux® (SELinux), technologies in Red Hat Enterprise Linux that were specifically developed to detect and prevent complex security threats present in today’s IT environment.
HIGH PERFORMANCERed Hat Virtualization has demonstrated consistent leadership in industry-accepted virtualization benchmarks—SPECvirtensuring better virtual machine (VM) performance, faster management control, and greater scalability responsiveness.
NO VENDOR LOCK-INRed Hat Virtualization provides freedom and flexibility to support your IT infrastructure. It is an open, software-defined solution. Community-designed with the continuous input and participation of Red Hat  engineers, Red Hat Virtualization delivers on the value of a Red Hat subscription with a certified ecosystem of software and hardware partners. Provided application programming interfaces (APIs) and software development kits (SDKs) help to extend and support the Red Hat solution to your existing and preferred management tools.
