According to Gartner’s Magic Quadrant for x86 Server Virtualization Infrastructure 2015, about 75 percent of x86 server workloads are currently virtualized. What began some eight to ten years ago as a way to consolidate underutilized physical systems into less costly virtual ones has become an industry standard.

If Gartner’s estimate is correct, then most companies are now taking advantage of the reduced cost and increased agility that virtualization offers its converts. Server virtualization has led the way to more efficient hardware that can support dozens of virtual workloads as independent operating systems that look and feel just like their physical counterparts. It has also led to hardware-enhancements for virtualization, more efficient disk space allocation, better virtual host software, shorter system boot times, and better overall hardware utilization.

In Gartner’s report, it noted seven leading companies that have distinguished themselves above the din of noise in this space. This list profiles those companies and provides information based on their market positions and offerings in the server virtualization space. They are in no particular order.

VMware – ESXi

Key differentiators: Longevity, EMC is its parent company, strategic partnership with Cisco, a huge global install base, customer satisfaction, long list of support guest OSs, and third-party support.

Since it created the x86 server virtualization market back in 1999, VMware has been the dominant market leader. VMware continues to innovate by adding new features and capabilities to its long list of virtualization and associated support products. Businesses of all sizes from the smallest mom and pop shops all the way up to the world’s largest enterprises use VMware’s scalable virtualization solutions. Gartner’s surveys reveal that about half of all midmarket companies, those with 100 to 1,000 employees, use VMware.

VMware supports a very long list of guest operating systems including Windows, Mac OS X, Linux, FreeBSD, Solaris, NetWare, and others. It supports every major hardware manufacturer’s server systems that either use Intel or AMD CPUs with virtualization enhancements. VMware can use a variety of different storage types including local disk, SAN, NAS, and USB-attached storage.

Although VMware’s cost is comparatively high, its customer satisfaction is also very high.

Microsoft – Hyper-V

Key differentiators: Microsoft’s support, ubiquitous footprint, easy-to-use interface, longevity, and cost competitiveness.

If VMware is server virtualization’s 800-pound silverback gorilla, then Microsoft is the 400-pound adolescent who wants to be virtualization’s alpha prime. Although it doesn’t have the longevity or the guest operating system support that VMware does, it supports the major Linux distributions and all Windows operating systems, which it assumes is 99 percent of any datacenter’s install base.

Although Microsoft’s Hyper-V runs a distant second place to VMware’s market share, it is a strong contender because of the ubiquity of Microsoft server operating systems in data centers. Microsoft has also made its Hyper-V offering very wallet-friendly by offering free guest OS licenses when purchasing certain host operating systems and it’s having an impact on VMware’s market dominance.

Microsoft has also closed the functionality gap between VMware’s features and Hyper-V’s. The biggest problem that Microsoft faces with Hyper-V as a VMware challenger is that its host OS (Windows server) is far more vulnerable to malware, security-related hacks, and downtime related to patching reboots. Additionally, it lacks the guest OS density that customers enjoy with VMware. And although Microsoft has made some inroads in its operating system stability over the years, its overall customer satisfaction still suffers. It continues to face management tools problems and increased competition from open source solutions.

Odin – Virtuozzo Containers for Linux and Windows

Key differentiators: Virtuozzo containers for Linux and Windows, highest virtual machine density for server virtualization, large service provider install base, and low cost.

Odin, formerly Parallels, offered container virtualization before it was a thing. For years, they’ve offered service providers a way to maximize profits, maximize multi-tenancy, and minimize security risks of a multi-tenant, hosted services community. Although Odin has primarily focused on service providers, it does see the potential for enterprise adoption. Odin is the creator and major contributor to the OpenVZ project, which is an open source version of its Linux Virtuozzo container offering.

OpenVZ, in its ten-year existence, has gained widespread popularity in multi-tenant hosting environments and is the container virtualization engine in the hybrid open source hypervisor, Proxmox.

Odin’s biggest differentiator in the x86 server virtualization market is its Windows Virtuozzo container technology. This technology makes multi-tenancy for providers and enterprises easy and cost-effective. Windows containers work in the same way as their Linux counterparts do. The host system has its resources divided up into containers that share some files, the Windows kernel, system memory, and underlying hardware. Like Linux containers, Windows containers have their own IP addresses, their own users, and their own complement of applications. The container functions like any other Windows system. However, Windows virtual private server (VPS) administrators don’t have to worry about patches, drivers, or other host-oriented software. For most users, they never know that the system they’re working on is a container.

Competition has tightened up on Odin as containerized application solutions such as Docker and rocket become mainstream. Microsoft has added additional competitive pressure in the service provider market with its Azure cloud-computing platform, although many providers offer both Odin and Microsoft options to their Windows customers.

Huawei – FusionSphere and FusionCloud

Key differentiators: Products leverage open source software including OpenStack, Xen, and KVM, offers a full complement of server virtualization hardware and software, and is popular in emerging markets.

Huawei is very strong in China (its headquarters) and other emerging markets, such as Russia, Brazil, and India, with its ever-growing portfolio of virtualization hardware and software. Its OpenStack-based architecture makes its technology palatable to those who appreciate a more open source type business model. Huawei also touts its end-to-end security hardening, multiple disaster recovery plans, and other security features such as Trusted Computing and Trusted Platform Module.

Huawei, although widely accepted in emerging markets, has yet to break into mature markets, such as North America mostly due to national security concerns. However, analysts believe that this resistance is less of a security issue and more of a geopolitical one. Most of its referenceable data comes from China, companies should research the levels of local support, certification, and interoperability.

Oracle VM

Oracle – A pioneer in the RDBMS market with more than 35 years in the global marketplace, financial strength, large install base, superior support, owns Solaris operating system, able to leverage zone computing (containers).

Oracle VM is Oracle’s virtualization solution based on the Xen hypervisor. Interest in its virtualization technology is mostly from customers wanting a single vendor solution and Oracle provides special software licensing pricing for those customers choosing to use Oracle VM. Although Oracle has certified its software on Hyper-V, the special pricing does not extend to those using it. Oracle VM is a Xen hypervisor built on its Oracle Linux distribution, which is a Red Hat Enterprise Linux distribution optimized for Oracle workloads. Although KVM is a full server virtualization technology, Oracle also offers Solaris Zones and Oracle Linux Containers as part of its virtualization portfolio.

One Oracle solution advantage is its Enterprise Manager product that allows administrators to manage and monitor applications, infrastructure, and is the service delivery platform for cloud services. For companies looking for a single vendor solution for virtualization, database-related products, or enterprise applications, Oracle covers the gamut, but just as often its push for an Oracle-only stack limits its broader market potential and appeal.
