Considered Multiple Products
Oracle VirtualBox
Chose Oracle VirtualBox
I have used VMware ESXi for the purpose of running virtual productions servers. It's a different use case from VirtualBox, but they can be compared in some aspects:
- Both have room for improvement in UI - but VBox is somewhat more intuitive
- Both have decent performance in …
Chose Oracle VirtualBox
It's much more useful than VMware Workstation Player because you can't edit anything at all with that free version of vmWare. This is just about as capable as VMware Fusion and Workstation until you pay even more to use vSphere, and then you start having enterprise features.
Chose Oracle VirtualBox
Since OracleBox can do most of what VMware can, but free, the benefit is obvious. The quick set up and tear down are also a huge benefit. I chose Oracle VM VirtualBox for these reasons primarily, but there are countless others too. I would definitely say that this is the way to …
Parallels RAS
Chose Parallels Remote Application Server (Parallels RAS)
Parallels Remote Application Server (Parallels RAS) provided the most cost effective option for virtualizing applications.
Chose Parallels Remote Application Server (Parallels RAS)
We love the easy integration and functionality on the client side. With Citrix Workspace we always had connectivity issues and re-logins, which we never had with Parallels RAS. Awingu was also a good choice, because of its browser-only approach, but sometimes it is too …
Chose Parallels Remote Application Server (Parallels RAS)
Parallels compared to just using Microsoft's straight built-in functionally to their Windows Server is simply a cost vs reward scenario. In other words, you can save a bunch of money not using Parallels and just using MS built-in functionally. However, it likely won't work as …
Chose Parallels Remote Application Server (Parallels RAS)
Citrix Virtual Apps has too many constraints to integrate into our corporate network.
Chose Parallels Remote Application Server (Parallels RAS)
The management of Parallels Remote Application Server was much easier, the cost of licenses and yearly maintenance was lower, their support team was much more helpful then their competitors and the initial server setup was faster. We had our system up and running in as little …
Chose Parallels Remote Application Server (Parallels RAS)
Our previous Citrix environment was aging, and when we spoke with our ERP vendor, and discovered that they were using Parallels Remote Application Server as their own hosting platform for hosted clients, it made it an easier decision to deploy knowing that they were using the …
Chose Parallels Remote Application Server (Parallels RAS)
Cost and the support we got as we reached the decision. Also, the continued support as the organization has grown.
Chose Parallels Remote Application Server (Parallels RAS)
Parallels is less expensive to both purchase and maintain, easier to implement, easier to support, and easier to comprehend overall. Also, the product name doesn't change every week.
Chose Parallels Remote Application Server (Parallels RAS)
Set-up is many times faster especially for remote/external access. It takes hours with Parallels instead of the days it takes with other alternatives.
VMware ESXi
Chose VMware ESXi
At the time we did our comparison we found that VMware scaled much better than Hyper-V, lighter weight, and much more reliable. My recommendation if Hyper-V is needed for anything such as Windows containers, is to use nested virtualization and installing Windows Hyper-V within …
Chose VMware ESXi
Compared to VirtualBox, VMware ESXi feels a lot more enterprise-grade when comparing the two. As ESXi is a VMware product we knew the level of quality and support we would receive from the vendor. VirtualBox is an open-source platform for virtualization and we liked the fact …
Chose VMware ESXi
Unfortunately I haven't had the opportunity to use much of any of the alternatives to ESXi. Just Hyper-V for a bit, but not enough to give a definitive answer on.
Chose VMware ESXi
Building and operating in a virtual environment would be impossible without a reliable and efficient virtualization platform, such as VMware and Hyper-V. Before deciding which platform to choose for conducting your business operations, consider the differences in VMware and Hype…
Chose VMware ESXi
ESXi is hands down the winner when compared to its competitors, in terms of technical capability. VMware has maintained its leadership role in virtualization technology. Hypervisors from Microsoft, Oracle, Citrix pales in every way when compared to ESXi. Have you ever heard …
Chose VMware ESXi
We used Oracle VM VirtualBox for sandbox and local testing. It is not a HyperVisor, but a virtualization platform. It requires a Host OS to install on. When we implemented VMWare ESXi, the cost of Citrix Hypervisor was more, and Hyper-V was still in its infancy. Ultimately the …
Chose VMware ESXi
While all of the above hypervisors have their pros and cons, ESXi has the advantages of being free, well supported by the community, easy to setup, easy to use, and good hardware support.
Chose VMware ESXi
I have worked with several other virtual machine platforms such as Microsoft Hyper-V and Oracle VM VirtualBox and find not only the ESXi is a better platform for us, ESXi also seems to be easier once you have learned the basics.

Oracle
It is best suited when you want to have different operating systems on your laptop or desktop. You can easily switch between operating systems without the need to uninstall one. In another scenario, if you expect some application to damage your device, it would be best to run the application on the VM such that the damage can only be done to the virtual machine. It is less appropriate when time synchronization is very important. At times the VMs run their own times differently from the host time and this may cause some losses if what you doing is critical. Another important thing to take note of is the licensing of the application you want to run your VM. Some licenses do not allow the applications to be run on virtual servers so it is not appropriate to use the VM at this time.

Scenarios where time is a factor in having a solution in place and up and running safely and securely. Where there are older devices that ordinarily wouldn't be up to the task of running modern apps and services. Where users need to work away from the network, and security is a concern.

  • The printing driver is quite excellent, both in the Parallels Client and on the HTML5 client.
  • Setup is incredibly easy; the default setup is very functional, and adding features is a breeze.
  • Speed is very acceptable in general for end-users, the clients adapt quite well to the amount of bandwidth available, and features are available to adjust further.
  • Automation through PowerShell is great.
  • Support is usually quite fast and efficient.

  • Resource management. The automatic load balancing works very well to ensure no host is taxed disproportionately compared to the others.
  • Templates and cloning. It is very easy to set up a template and spin up new servers based on a specific setup. This makes server management very streamlined.
  • VM management. The vSphere interface is very easy to use and navigate. Everything is responsive and it works when you need it to. The options are also robust while also being arranged in a straightforward manner.

Cons
Oracle
  • I have had issues in the past when it has come to resizing VM disk storage. The issue is entirely detailed here: https://www.virtualbox.org/ticket/9103 -- the problem was caused because of having existing snapshots (which error message output was not detailing). I haven't had to deal with the issue due to my dynamic disk sizes not being small from the start anymore (this is mostly an issue for my Windows VMs where the base disk may need significant size for the OS). It looks like, for a resize, that a merge of all snapshots has to occur first -- one user on that list details a workaround to maintain snapshots by cloning the VM. (Note: 5.2 was just released a few weeks ago, and looks like it should prevent the problem happening in the future by properly informing users that it isn't possible with snapshots).
  • Certain scenarios, like resizing disks, required dropping into a terminal as there were no options to previously do so via the GUI. According to some recent posts, I've seen that v5.2 has added disk management stuff like that to the GUI (or will be adding it). I'm comfortable with dropping into the terminal, but in a teaching scenario or when evaluating the learnability of the tools, it complicates things.

  • Parallels Remote Application Server (Parallels RAS) continually improves the product but has broken some features recently. For example the web management portal lost the ability to manage user sessions after a major update. That issue was fixed in a later release
  • Multi-monitor support beyond 4 monitors (It does handle up to 4 -1080 monitors well)
  • More options around connection security and MFA. current options are sufficient but limited
  • We've noticed some performance issues with Windows Server 2019 and 2022. I'd like to see more robust support for remote applications running from those platforms.

  • VMware ESXi can improve on the UI that is installed on the bare metal machine. The menus can be hard to navigate when looking for simple configuration items.
  • VMware ESXi can improve on the stability of their overall hypervisor. There have been a few times we had to reinstall due to corruption of VMware ESXi.
  • I would like to see VMware ESXi do better at adding more standard free features in their consumer version of VMware ESXi. For example, having the ability to back up virtual machines is good practice and something that would be very nice if offered in their free version.

We have been using Parallels since it was called 2X - it is a major part of how we do business. It is fairly simple to use and maintain - staff like it, we like it. It is a product that makes a promise - and it keeps it. As Parallels evolves, and clean bandwidth becomes more readily available everywhere - it just makes sense to continue to use Parallels in our environment

I love using the Graphical User Interface. The VirtualBox Manager is very easy to understand and use. You can quickly create, configure and manage all your virtual machines in one window. It makes operating virtual machines easy and simple. When using VBoxManage it gives the user comprehensive control over VirtualBox so that you can use automation and scripting at the command-line interface

Parallels RAS was easy to setup, with great admin guides and resources. We especially liked the included Visio templates which made diagramming much easier. The reference deployment diagrams also simplified our deployment process. Our end users love Parallels RAS. Apps launch faster than Citrix, and the Parallels RAS client is far more reliable than Workspace.

The interface is fairly intuitive for most things, and the areas that are a little less obvious usually have fantastic documentation in the online knowledgebase. In 3-4 years of managing our ESXi hosts, I think that I have only opened 4-5 support cases for things that I could not figure out myself or find answers to on the website.

If there are any issues with Parallels - they are usually more about the server operating systems than Parallels itself. It would be rare for us to have any reason to take Parallels offline - we schedule a reboot on the servers at 3am to keep the O/S itself fresh, but again - it is not a Parallels issue. If individual users have any issues we ask them to completely log out of parallels - which ends their session - and then back in - and that typically resolves the issue right away.

Without the need to patch the servers with bug fixes and enhancements we whave not experienced any downtime with VMware issues. Even the bug fixes and updates do not cause of downtime as we just migrate the servers to the opposite node and update the one and then move servers back. Very simple and painless.

I am giving Parallels 9/10 on this one because the only application that sometimes seems slow or has issues - is Microsoft Outlook. It is sometimes the result of a pop-up that may not show up in the published application (vs full desktop). Other than that - pages load very quickly - and it does not seem to slow down other applications that are running at the same time. Most of our users run Outlook, softphone and Teams locally - and published applications for everything else. When they do that - it is very solid.

I can't say enough good about VMware's support team. To an individual they take ownership of the case, provide thorough answers, and follow up regularly. On one occasion, a problem we experienced with NSX Endpoint was escalated to development for a permanent resolution after a workaround was found. In my experience, most companies would have tried to find a way to close a case like that instead of taking it all the way. Most importantly, when production is down and every second counts, they VMware teams understand that urgency and treat your issue as if it were the only one they had to deal with. You can't ask for better.

Overall, it was pretty simple compared to most other projects. Again, we had a strong familarity with the product so there was not much of a learning curve. Our 'biggest' issue is the end-user understanding of a 'local' application and a published application. For example - Online meetings need to run locally for camera/video to work smoothly so opening a link to a meeting from a published application continues to be an occasional issue.

VirutalBox is very similar to using Vmware with the slight difference in appearance and what might be considered a less polished look.

As long as you're using Nutanix AOS on Nutanix hardware and are paying their software support fees, AOS is a valid competitor to VMware and can save money due to not needing a license and having their server management system built into the base host management system. If you aren't using Nutanix hardware, however, VMWare is in most cases the best way to go. I cannot comment on HyperV, but most IT people I know either use it because they have to (most) or they like it better (not many).

The only problem I have found is that the deployment is dependent and intrinsically linked to the Host OS. This is different from bare metal solutions which remove that dependency on a Host OS. The latter is more reliable and removes a layer of potential failure.

Return on Investment
Oracle
  • Minimal-to-no support needed from the DevOps team.
  • Provides a direct and an easy way to access multiple VMs inside the same machines which enables performing various testing and QA tasks without the need to switch hardware.
  • Automatic provisioning using tools (esp. Vagrant) which enables developing a base image once, and allows for exporting/importing anywhere across the developers team.
  • Very cost-effective (no fees or monthly subscriptions).

  • Our customers have had dramatic cost decreases due to no longer needing IT departments to work with our software.
  • We've been able to charge more for our hosting services due to our customers saving money in the long run. Parallels Remote Application Server has more than paid for itself, and the increased income has gone right back into the business.
  • Both our customers and our company have benefited from this transition.

  • VMWare ESXi licensing is affordable for our business - and the licensing model is simplistic. Not like that of Microsoft with having to keep track of server licenses and CAL licenses for users.
  • VMWare ESXi also has hardware-monitoring built-in, so that further saves us money from having to be spent with another vendor.
  • As much as I hate the saying "a single pane of glass" does fit for this product. You can manage your servers, monitor hardware status, create and export backup snapshots, manage virtual NICs, connect to various storage devices. We're very happy with this product.
