For me personally all of the above are relevant, (except comments like virtual environments are very easy to use, but yet very hard to manage, they're not, they're just different and require more than a Windows Skillset) however I traditionally start from where its going to end and so the question is, what is this going to leave behind? What is the legacy of implementing this? If implementing something causes a technology or vendor lock in, massive support costs, proprietary hardware, specific skills training etc, then it is to be given serious deliberation as to whether it is viable option for the business/organisation in the long term. So my most important criteria is legacy followed by Can we do a Proof of Concept for free therefore minimising investment to just engineering time.

A good solution must meet a balance between cost, performance, management, availability and scalability.

2015-08-24 03:38:15 UTC24 August 15

I agree with all of the above I will add a -no nonsense approach-...a big dose of simplicity--many a software that has a great capability is immediately thrown out by users or Tech guys and cause a tremendous loss of business hours because of its highly Academic approach and fancy wordings. Here are some examples..Yahoo is successful because of its straight forward interface.
Google one line search approach is another example..Windows 8 was not successful because of its nonsense interface..VMWare workstation is the best example of a successful Interface...One will not need much support if the software is TIDY..in today s age time is of the essence...Tech people must be able to intuitively navigate and learn on the spot and so are the user .so INTERFACE is KEY followed by what the gentlemen described.

When you are researching by a virtualization solution, you must to have in mind what you hop from this technology and how much do you intend to grow (how their environment can grow in a not too distant future).
With this in mind, you can see that we have many possibilities, but some one of them can generate additional costs if you have to increase the environment in a short time period.
Based in this criterias, you need to consider ROI and Scalability as main characteristics to acquire a virtualization system.
In a first moment, a cheaper solution can seems the best, but as said before, if you have to increase the environment quickly, this solution that seemed cheaper could become the most expensive.

For me, the most important factor is whether it meets the customer's needs or not. There are many use cases for all of the virtualization platforms and not one does everything perfectly. Price is always a factor in meeting the customer's needs, a lot of times the feature list comes after the price.

Virtualization most important criteria
- scalability (being ability to move and build more without outage)
- flexibility, and resiliency (hardware outage without application outage)
- stability (knowing that the system will be available)
- manageability (managing the system with solid tools, and not have to manage the system everyday)

As both a VMWare and Microsoft HyperV instructor, I get to experience both products in a classroom environment as well as a live environment. I look for stability and scaleability first and foremost. By far, VMWare wins hands down in these areas except costs. Now with VMWare NSX (Virtualized routing and Switching) VMware has taken the lead in this area as well. Microsoft is well behind.

The most important criterias when looking for server virtualization software are: business support, certification, features like snapshot, cloning and backup and finally, openess. Clear and supported procedures on how to migrate between the major Virtualization platforms should be made available to make you feel confortable with the choice you make and provide you a way to migrate to an alternate platform in the future.
