Open source, cross-platform, virtualization software that enables developers to deliver code faster by running multiple operating systems on a single device, used to deploy applications on-premises and to the cloud. Oracle VM VIrtualBox is Oracle's cross-platform virtualization offering, acquired with Sun Microsystems in early 2010. The software was originally developed by Innotek GmbH.
Citrix Virtual Apps & Desktops is best in class for offering a great user experience in VDI, server-based sessions, or published apps. Using additional GPU allows uses like rich video, 3D apps, and great modern uses (MS Teams, Office 365, Zoom, etc.). Citrix products are very well integrated (Citrix Virtual Apps & Desktops used with Citrix ADC is the best way to secure access and monitor everything).
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.
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.
Getting the environment setup took me three months of off and on work, with 3 complete rebuilds of the environment. Utilizing the WebUI to access the environment had presented so many random issues that we had to require end users to use the Citrix Reciever App. As it was the only stable solution. Aside from that, it hasn't required much admin intervention since the stand-up was completed.
Easy and quick to use. Runs at sufficient speed even with 5/6 VMs running, and can handle a bridged network with ease. Easy to disassociate from the host to ensure the environment built within VB is quarantined should anything happen, meaning no risk to physical hardware. Quick to pick up. Quick to add new machines. Cloning feature very quick and comprehensive. I've never had a VM crash or freeze.
The performance of XenDesktop is the best in the industry because of the fine-tuned protocol and years of updating. Overall, I don't think there is a better performer on the market. The question is if the added complexity of running XenDesktop is really worth the performance gain. While the latest version of XenDesktop is the easiest to deploy so far, it is still more challenging than the competitors.
The support is great when you get an engineer that knows what they are doing but getting that individual sometimes takes a while. Overall, they are professional and polite and competent in their knowledge. Sometimes the cases are open for an extended period of time which becomes very frustrating when dealing with critical issues.
Take it slow and read the directions each step of the way. If you are not familiar with Citrix products, use a reseller or other experienced engineer to assist you in the setup of your environment
I never had the chance to test other products like these since whenever I read and searched online during the first phase it was only popping up Citrix Virtual Apps and Desktops.... so we got in touch with the sales department and the rest is history. After the technical consultation, it was more obvious that the implementation would have been very easy and the security layers are very well for my company.
VirutalBox is very similar to using Vmware with the slight difference in appearance and what might be considered a less polished look. However, what it lacks in polish and looks it makes up for in functionality, easy of use and the wide range of operating systems and features it supports without the need of buying the full professional edition
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.
XenApp has allowed us to continue support of legacy applications and all access of those applications to users across the globe with any device.
XenApp can also manage software licenses by restricting number of users, number of concurrent sessions, or combination of both to required specification.
While initial investment in XenApp can be costly, continuing support and upgrade are very cost effective and product stability is excellent.
While there are competing products from Microsoft and VMware, when it comes to remote application access, XenApp is the best of breed.
For personal use, there is no monetary investment, I am running 5 CentOS servers flawlessly in my home lab.
Saves a ton of money in an enterprise environment by not having to purchase physical test servers. (Cost of Enterprise product is way lower vs Cost of standing up physical servers and/or cloud servers)
Makes virtualization very easy and friendly for everyone for test instances.
