An Overview of Virtualization Solutions - Conclusions
(Page 4 of 4 )
As you can see, we've reached the end of this article. This means that you have actually learned about some of the available virtualization products and their features. One thing to be mentioned, though, is that you can’t really decide which one to use before you actually try all of them out. The choice is only yours and ultimately it comes down to personal preference.
In the case of business environments, chances are you will go with either VMWare of Microsoft Virtual PC, mostly because they both come for free and can be used in professional environments as well without licensing. The latter VirtualBox by Sun might require re-compilation of the code if it needs to be run in those situations (e.g.; at work).
Furthermore, please be aware that running an emulated operating system also requires appropriate licensing and acceptance of the EULA. This means that if you intend to run a virtualized copy of Windows XP, for example, on your current OS, then you ought to have a legit copy of Windows XP with a valid installation code. In the case of Linux/GNU, OpenSolaris, and FreeBSD operating systems, this won’t be a problem.
It should also be noted that virtualization relies on the available hardware resources, and this becomes a truly important factor in the case of numerous virtual machines. Surely you can emulate servers as virtual machines as well, but please consider the efficiency of the virtualization. Even though the rate of native code execution is high, there’s no way the performance of an emulated OS can be compared with a truly native one.
“VMware operates dramatically faster than emulators, running at more than 80% of the speed that the virtual guest operating system would run directly on the same hardware. VMware claims an overhead as small as 3% to 6% for computationally-intensive applications.” —Source: Wiki.
