The biggest feature that we like and which is most valuable for us is the fact that Virtualbox is easy to set up, it's ready to go, and we can install Oracle PeopleSoft images on a Linux OS in a fairly quick and efficient time with minimal manual work.
Improvements to My Organization
Our ability to keep up with Oracle PeopleSoft images being installed on the Oracle VM has sped up our turnaround time and allowed us to save time for applying updates to a delivered environment to begin analysis\extraction of fixes and review of functionality.
Room for Improvement
There were some minor issues with the initial setup, such as if we forgot to reinitialize the MAC addresses of the network cards. Also, setting up the network adaptors was a bit tricky.
Use of Solution
I've been using it for about six months.
We went with a physical box, and our biggest issue was being able to get right amount of configuration/memory/disk space and CPU to be able to deploy multiple images on the VM. Realistically the restriction was on our end and not the software itself.
We have had no issues with the stability.
We have had no issues scaling it for our needs.
Customer Service and Technical Support
The level of customer service and support has been very good to date. No complaints there.
The initial setup was pretty straightforward with some minor items that needed to be logged. The biggest issue we came across was if we forgot to reinitialize the MAC addresses of the network cards. If we forgot to do that, we had to go back and re-import the image to the Virtualbox. Setting up the network adaptors was a bit tricky, in the sense where we had to make sure we had enough adapters to do Bridged Adapters.
We implemented it in-house.
The ROI on it is obviously to our benefit as we are now able to deploy multiple PeopleSoft images to the Oracle VM and have everything (Web\App\DB\OSES) up and running normally in less than a day. That is a big time saver for us.
Pricing, Setup Cost and Licensing
In our situation, the product came as part of our ERP license, therefore we cannot comment on that as its not a separate cost.
Other Solutions Considered
We did not evaluate any other solutions as the Oracle VM was part of our ERP deployment with the new release. It was a requirement and, as such, we implemented it accordingly.
I would say that in terms of implementing this product, it is definitely a powerful tool and what we are using it for is probably less than what it can be used for to maximize the return. Being able to run multiple images on this (Windows, OS X, Linux, Solaris, IBM OS\2 etc.) allows for deployments of multiple OS's and version for testing multiple products\scenarios.
