Likelihood to Recommend Ubuntu OpenStack is well suited for startups where there are very tight financial constraints. As Ubuntu OpenStack is open source, the startup organizations will not have to spend a lot when compared to their commercial offerings in the market. Ubuntu OpenStack is less appropriate in organizations where they don't want to have private on-prem clouds. As deploying a private on-prem cloud is a very cumbersome and tedious task, the organizations must have a dedicated team to manage such on-prem deployments.
Read full review 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.
Read full review Pros Very easy to use, learning curve is very short. Don't need to invest months of training before using it Well suited with Jenkins for automated tests Works well on large sets of heterogeneous hardware Read full review It is simple to install - there is no advanced knowledge required to begin building virtual computers It is easy to use - adding new virtual machines is simple with wizard-based deployment It enables easy portability - moving virtual machines from one host to another is straight-forward and simple It is free Read full review Cons More customizable options while choosing virtual machine configurations would be great. To have regular online learning sessions directly from Ubuntu OpenStack experts [to] help users and for those who implement it. Giving admin more control on what privileges they can grant to their users. Read full review 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. Read full review Likelihood to Renew I give this rating because virtual box is inexpensive but there is another product such as vm ware that can also be used
Read full review Usability 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.
Read full review Reliability and Availability Dependency on the Host OS means it is as reliable as it is possible to be. Application errors are beyond the purview of the application.
Read full review Performance No issues, especially with the extensions addons.
Read full review Support Rating Oracle have a very fast response rate and a strong user community. One can geet help from many sources if they choose to research for themselves.
Read full review Implementation Rating We really enjoy using virtual box. We do not require to buy expensive hardware but instead we can minimize costs and maximize profits.
Read full review Alternatives Considered Everybody knows VMWare which is the world's number one in data center infrastructure management. OpenStack is lot lot less expensive but doesn't offer all the functionalities you have with VMWare especially for High Availability and load balancing. You should go for OpenStack if you need an easy to use solution without the need for external consultants. If you don't have the capacity to manage your own infrastructure you had better go for VMWare.
Read full review 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
Read full review Scalability 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.
Read full review Return on Investment Lighter on initial spending for the organization. Deployments which have no vendor locking makes management decisions easier. Support from great community saved lot of time for engineers managing it. Read full review 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.
