Virtualization Software Market in 2019: Key Vendors, Segments, and Growth Drivers

Virtualization software has become a cornerstone of modern IT infrastructure, enabling organizations to abstract hardware resources, improve utilization, reduce costs, and deliver flexible computing environments. This article provides a practical overview of the global virtualization software market as it stood in 2019, including the leading vendors, market segments, regional trends, and the strategic questions organizations need to ask when evaluating this space.

What Is Virtualization Software?

Virtualization software allows a single physical machine to run multiple isolated operating system instances, known as virtual machines (VMs). Beyond server virtualization, the category encompasses desktop virtualization, application virtualization, network virtualization, and storage virtualization. The technology underpins cloud computing, DevOps pipelines, disaster recovery, and remote work infrastructure.

From a classification perspective, virtualization software is commonly split into two broad types:

• Type I (Bare-metal hypervisors): Run directly on the host hardware without a host operating system. Examples include VMware ESXi and Microsoft Hyper-V. These are preferred in data center and enterprise environments for performance and isolation.
• Type II (Hosted hypervisors): Run on top of a conventional operating system. Examples include VMware Workstation and Oracle VirtualBox. These are common in developer workstations and testing environments.

• Evolve IP: A cloud services provider offering hosted virtual desktops and unified communications built on virtualization technology.
• Mitel Networks: Focused on virtualized unified communications and contact center solutions.
• Nomadesk: Provided virtual workspace and file-sharing solutions, primarily targeting mobile and remote workers.
• PayStand: A B2B payments platform; its inclusion in virtualization market reports of this period likely reflects its cloud-native, software-defined architecture rather than a core hypervisor offering.

Market Segmentation by Application

Virtualization software deployments in 2019 were commonly analyzed across two broad application categories:

• PC / Desktop Terminal: Virtual desktop infrastructure (VDI), application streaming, and hosted desktop environments delivered to end-user PCs and thin clients. Key use cases include remote workforce support, BYOD security, and centralized desktop management.
• Mobile Terminal: Mobile device management (MDM) integrated with virtualization, containerized mobile apps, and mobile VDI solutions enabling secure access to corporate environments from smartphones and tablets.

Regional Market Focus

In 2019, virtualization software adoption was strongest in mature enterprise markets, with significant variation in growth trajectories across regions:

• North America: The largest market by revenue, driven by widespread enterprise cloud adoption, strong data center investment, and mature DevOps practices.
• Europe: Solid adoption, with growing interest in private cloud and hybrid deployments, partly driven by data sovereignty and GDPR compliance requirements.
• China and Japan: Significant and fast-growing markets, with China’s cloud infrastructure build-out accelerating demand for hypervisor and container technologies.
• Rest of World (India, Southeast Asia, Central & South America, Middle East & Africa): Emerging markets with strong growth potential, often leapfrogging legacy infrastructure in favor of cloud-first virtualization deployments.

Key Market Drivers

Several factors were propelling the virtualization software market forward in 2019:

• Cloud migration: As enterprises moved workloads to public, private, and hybrid clouds, virtualization served as the foundational layer enabling workload portability and resource pooling.
• Cost optimization: Server consolidation through virtualization continued to reduce hardware capital expenditure and data center footprint.
• DevOps and CI/CD adoption: Development teams relied on VMs and increasingly on containers (Docker, Kubernetes) for consistent, reproducible build and test environments.
• Remote work and VDI growth: Demand for secure, managed remote desktop access was already growing ahead of the mass remote-work shift that followed in 2020.
• Disaster recovery and business continuity: Virtualized environments made snapshot-based backup, rapid failover, and site replication significantly more practical.

Key Market Restraints and Challenges

• Complexity and skills gap: Managing large-scale virtualized environments requires specialized expertise that many organizations struggled to source and retain.
• Licensing costs: Enterprise virtualization platforms, particularly from VMware and Citrix, carried significant licensing overhead that deterred smaller organizations.
• Container competition: The rapid rise of container orchestration platforms like Kubernetes began to challenge traditional VM-based virtualization for greenfield workloads, creating uncertainty about long-term hypervisor market share.
• Security concerns: VM sprawl, hypervisor vulnerabilities, and shared-resource attack surfaces required dedicated security tooling and governance processes.

Strategic Questions for Organizations Evaluating Virtualization Software

When assessing virtualization platforms and vendors, engineering and operations teams should consider the following:

1. Which workload types need virtualization? Distinguish between server consolidation, VDI, application delivery, and network/storage virtualization — each has distinct tooling requirements.
2. What is the target infrastructure model? On-premises bare-metal, private cloud, public cloud (IaaS), or hybrid? Your hypervisor choice and management tooling must align with your operational model.
3. How does this platform integrate with existing DevOps toolchains? Evaluate API support, Terraform providers, Ansible modules, and CI/CD pipeline integrations.
4. What are the total cost of ownership (TCO) implications? Factor in licensing, hardware, operational overhead, and training — not just sticker price.
5. How does the vendor’s roadmap address containerization? Vendors like VMware (with Tanzu) have invested heavily in Kubernetes integration; evaluate whether your chosen platform bridges VMs and containers effectively.
6. What monitoring and observability tools are needed? Platforms like Datadog, ManageEngine, and others provide VM-level and application-level visibility that is essential for managing virtualized environments at scale.

SWOT Considerations for New Virtualization Projects

Organizations evaluating new virtualization investments in this era typically weighed the following factors:

• Strengths: Mature technology, broad vendor ecosystem, proven ROI through server consolidation, strong disaster recovery capabilities.
• Weaknesses: High operational complexity, potential vendor lock-in, performance overhead compared to bare-metal for latency-sensitive workloads.
• Opportunities: Edge computing virtualization, 5G network function virtualization (NFV), and expansion in emerging markets.
• Threats: Container-native architectures reducing VM dependency for new applications, open-source alternatives (KVM, Proxmox) eroding commercial hypervisor share in cost-sensitive segments.

Summary

The global virtualization software market in 2019 was a mature but actively evolving space. Established players like VMware and Citrix Systems held dominant positions in enterprise server and desktop virtualization respectively, while adjacent vendors in monitoring, backup, and managed services rounded out the ecosystem. The market’s trajectory was being shaped by cloud migration, containerization, and the growing need for secure remote work infrastructure — trends that would accelerate dramatically in the years immediately following.

For DevOps engineers and infrastructure architects, the practical takeaway from this period is that virtualization remains a foundational competency — and that evaluating platforms requires looking beyond the hypervisor itself to the surrounding ecosystem of management, monitoring, security, and automation tooling.
