Hello, Let‘s Compare VMware vs VirtualBox

If you clicked on this article, chances are you are looking to virtualize servers, desktops, applications or data. So let me start with a quick primer on what exactly virtualization means and why platforms like VMware and VirtualBox matter.

Virtualization Overview

Virtualization enables running virtual machines (VMs) – software emulations of physical computer systems with separate operating systems inside one physical server or workstation. This provides tremendous benefits:

  • Consolidating hardware – Host many VMs using fewer physical servers
  • Isolating environments – Safely segregate apps, data, users
  • Improving continuity – Quickly migrate VMs if servers fail
  • Streamlining management – Centralize resources under one interface
  • Optimizing costs – Reduce overhead of electricity, cooling, real estate

The software providing virtualization capabilities is called the hypervisor or virtual machine monitor (VMM). This manages sharing hardware between guest virtual machines.

Now let‘s look at how two popular options – VMware and VirtualBox – compare as hypervisor solutions.

Purpose of This Comparison

Over their 25 year journey, VMware has expanded from bare metal hypervisors to building cloud management stacks, networking+security tools and app modernization software.

Q: Which company currently owns VMware?


Created: 2007 by software company Innotek, founded by Frank Mehnert and Hendrik Eeckhardt

Key Events:

  • 2010 – Oracle buys Sun Microsystems (including Innotek GmbH)
  • 2010 – Oracle renames Innotek VirtualBox to Oracle VM VirtualBox
  • Since then, Oracle maintains VirtualBox as free open source hypervisor

Originally created for Linux and Windows hosts, VirtualBox grew into cross-platform virtualization supporting enterprise use cases while remaining free.

Q: Who owns and manages VirtualBox today?

Now that we‘ve covered some key history on VMware and VirtualBox, let‘s move onto how they compare technologically…

Side-by-Side Feature Comparison

Here is a high-level overview of capabilities across categories:

Host Operating System SupportWindows, Linux, OS XWindows, Linux, OS X, Solaris

To interpret this table:

  • Both support all major host OS platforms like Windows, Linux and OS X
  • VirtualBox edges out VMware supporting additional niche guest and legacy OSes
  • VMware offers complete software suites and commercial licenses unlike FOSS VirtualBox
  • Advanced features like live migration only available with VMware
  • VirtualBox can work reasonably well on lower RAM environments

This summary provides a taste of differences. Now let‘s analyze some key distinction areas in greater detail…

Diving Into Distinctions Between the Hypervisors

There are several areas VMware and VirtualBox diverge when it comes to virtualization capabilities:

Performance and Efficiency

When benchmarking efficiency converting hardware resources into virtual capacity, VMware consistently outperforms VirtualBox by significant margins.

Some major advantages VMware delivers for intensive workloads:

  • Lower overhead – VMware intelligently leverages hardware with less wastage
  • Memory deduplication – Identical memory pages shared intelligently between VMs
  • Storage speed – VMware achieves nearly native disk performance
  • Graphics rendering – Smooth media playback utilizing GPUs for high FPS
  • Burstable microprocessors – Support for latest CPU innovations from Intel, AMD and Apple

An extensive performance analysis conducted by Red Hat engineers revealed VMware had substantial advantages over VirtualBox in CPU efficiency, storage I/O throughput, memory utilization and more.

So while VirtualBox meets basic performance needs for lightweight apps, media encoding, serious data crunching, and other resource-intensive use cases demand the horsepower VMware provides.

Let‘s discuss: Why does VMware typically achieve much higher performance benchmarks compared to VirtualBox?

Operating System Support Scope

Both VMware and VirtualBox support all of the most common consumer, business and server operating systems used today like:

✅ Windows 10
✅ Various Linux distributions (RHEL, Ubuntu, Debian etc.)
✅ Apple macOS

However, VirtualBox has greater breadth when it comes to niche or legacy guest OSes:

✅ Solaris as old as Solaris 10
✅ Oracle Linux, Illumos
✅ Obscure Linux forks and BSD variants
✅ OS/2 IBM operating system
✅ Some Windows legacy versions

So while the mainstream OSes have you covered in either platform, VirtualBox lets you virtualize a wider array of platforms.

Question: True or False – VirtualBox supports more total guest operating systems compared to VMware?

Licensing and Support

One major area VMware differs from VirtualBox involves licenses, commercial support, and pricing.

A quick comparison:

License TypeProprietary commercialOpen source
PricingRange from $200 – $4,000+ per CPU socket100% free
Support PlansProduction support contracts availableCommunity forums only

So companies like Oracle and individuals can freely download, install and run VirtualBox without any licensing costs whatsoever, enabling home labs and dev/testing environments on a budget.

However for full compatibility matrices, 24/7 critical production deployments and medium-large organizations, VMware requires and justifies the paid licenses and support costs.

Consider your business needs and budget when weighing the two options.

Question: What underlying license model does VirtualBox use?

This covers just a sample of difference areas – there are certainly more distinctions we could analyze further! But let‘s shift gears to look at ideal use cases now that we have a decent lay of the land…
