Though VMware is the market leader for virtualization solutions, there’s something to be said for open-source alternatives with enterprise-level support — like Oracle’s VirtualBox.
This article looks at how these multinational virtualization and networking giants fare when comparing their virtualization tools, free and premium features, and pricing.
Virtualization offers organizations small and large segmentation of computing power and application services while working across operating systems like Windows, macOS, Linux, Android OS, and iOS devices. For developers, hybrid compatibility is increasingly important, but today’s virtualization solutions also come with a bundle of advanced features.
Oracle VM VirtualBox and VMware vSphere both offer standard virtualization through their open-source and free versions. However, their enterprise features and licensing options are what make the solutions stand out and comparable.

The Oracle VM VirtualBox is the networking giant’s open-source solution, enabling multiple operating systems on a single physical appliance.
The base software package of VirtualBox offers standard virtualization capabilities for desktops and is compatible with Windows, Linux, Solaris, and macOS operating systems. Other core features include up to 32 virtual CPUs, live migration between virtual machines, and Guest Additions for optimizing performance and usability. With industry support for the Open Virtualization Format (OVF), users can seamlessly migrate existing virtualized systems to or from VirtualBox VMs.
The above capabilities all come free of charge with VirtualBox source code and platform binaries available under GNU GPLv2. Under the Personal Use and Evaluation Licence (PUEL), developers can also add Extension Pack features. These added features include disk image encryption, pass-throughs for host webcam and PCI, remote desktop protocol (RDP) support, and Virtual USB 2.0 (ECHI) and 3.0 (xHCI) devices.
Convenient for existing customers, Oracle offers commercial licensing and support with its Enterprise plans. Broader virtualization efforts can benefit from the Enterprise bundle’s patch management, centralized tracking of Extension Pack activity, 24×7 support, and multiple RDP connections per VM.
Oracle’s Enterprise plan is available for premium capabilities based on two metrics: named workstation users and sockets. At $50 per named workstation user, with a 100 minimum order quantity, the workstation route comes to $5,000. An additional $11 per workstation, or $1,100 for the minimum group, covers the software update license and support for the first year.
| Named Workstation User Perpetual | Workstation Users (MOQ: 100) | Per Socket | |
| VirtualBox Enterprise | $50 | $5,000 | $1,000 |
| License & Support | $11 | $1,110 | $220 |
| Total Cost | $61 | $6,100 | $1,220 |
Alternatively, prospective clients can also purchase the enterprise solution by the socket for $1,000 with the add-on cost of $220 for the licensing and support. The total for a single socket comes to $1,220. In both purchase routes, clients receive discounted prices with larger quantity orders.

Before vSphere, VMware’s flagship solution was its bare-metal hypervisor, ESX (now ESXi), for enterprise organizations deploying virtual servers. Eight years later, ESXi would join vCenter as the two core components of the vendor’s virtualization platform.
The vCenter Configuration Server is the centralized manager for a client’s virtual infrastructure, offering added visibility, automated controls, and application discovery. Administrators can manage VMs from the vSphere web client with enterprise-level virtualization tools that optimize the orchestration of virtual machines. Enterprise virtualization tools available to users include distributed switches, profile-driven storage, integrated containers, and more.
vSphere 7.0 was released in 2020 with a range of features to meet growing hybrid infrastructure needs. VMware’s native container management platform, Tanzu, is ready for application acceleration and modernization, offering integration to Kubernetes. With the Distributed Resource Scheduler (DRS), vSphere 7 provides application performance and resiliency by hosting large workloads beyond cluster-level load balancing.
Uptime continues to be critical to content delivery providers and IT operations, making both high availability and fault tolerance necessary features. Even in the face of hardware failure, vSphere hosts can automatically migrate to preserve services. Additional embedded security features include logging, auditing, encryption, and role-based access and control.

The vSphere solution is available for free or by upgrading to one of the vendor’s commercial licenses. Starting with the Essentials plan, clients get the ESXi hypervisor and vCenter for base-level virtualization capabilities. Essentials Plus adds vSphere Data Protection, High Availability, and vMotion for live migrations.
| Essentials | Standard | Essentials Plus | Enterprise Plus |
| $578 / year | $1268 / year | $5,596 / year | $4,305 / year |
For almost a fifth of the price of Essentials Plus, the vSphere Standard bundle includes vMotion, vSphere Replication, and vShield Endpoint, enabling robust image management, network security, and redundancy. The Enterprise Plus plan adds features like vSphere Trust Authority, data-at-rest encryption, and flexible IT services for modern hybrid infrastructures.

An early innovator in relational database management (RDBMS), Oracle has four decades of experience providing modern software solutions to enterprise clients. With headquarters now in Austin, Texas, the multinational IT vendor continues to push the limits of its offerings. Oracle’s acquisition of Sun Microsystems in 2010 included VirtualBox, released three years prior by German software company Innotek.
Over 20 years ago, VMware virtualized the x86 architecture for enterprise organizations. The Palo Alto-based vendor is an industry leader in virtualization with a stack covering desktop, server, cloud, application, and container management. According to IDC, VMware’s market share has fallen in recent years, yet remains dominant with almost half the market share at the end of 2020.

Oracle’s VirtualBox and VMware vSphere are two of the market’s leading options for enterprise virtualization, but what’s best for your organization?
While Oracle has a robust open-source solution, it’s hard to beat the virtualization tools offered by the industry-leading VMware. As features like clustering and backup APIs become increasingly critical, VirtualBox can’t compete with the stack of tools and capabilities vSphere has put together. VMware can also support twice as much RAM per host at 16TB, giving developers more room to work per VM in use.
The most recent Garter Magic Quadrant for x86 Server Virtualization Infrastructure placed VMware and Microsoft (Hyper-V) far ahead of more niche players like Oracle, Citrix, and Virtuozzo.
For developers looking to save on costs, VirtualBox holds the edge over VMware’s free plan. Oracle’s open-source virtualization software gives users more flexibility when considering modification and distribution relative to VMware’s proprietary licensing. VMware consistently offers enterprise solutions at a premium price, meaning some SMBs can’t or aren’t ready to invest.
Because the pricing models and features vary between solutions, it’s up to each organization whether Oracle’s per-named workstation or socket enterprise plans are more accommodating than VMware’s comprehensive virtualization coverage. At roughly $6,000, the minimum order (100) of VirtualBox workstations plus licensing and support isn’t much more than the vSphere Essentials Plus plan.
