A recent Hot Aisle poll about the use of hypervisor technology in enterprises offers some interesting insights.
- 96% of respondents use at least one hypervisor
- 44% of respondents use two or more hypervisors
- 16% of respondents use three or more hypervisors
- 98% of Hot Aisle readers know what a Hypervisor is (we are a smart bunch)
* The poll was restricted to the main x86 hypervisors – Xen, ESX, KVM and Hyper-v.
Hypervisor technology is now mature with extremely high penetration into enterprises, mid market and SME alike. A very significant number of organisations are using more than one hypervisor. This is most counter-intuitive as (although each has it’s own strengths and weaknesses) all hypervisors do essentially the same job.
There are a number of possible explanations:
- Licencing fees for the propriatary products is driving enterprises to adopt a second free product
- Vendor support arrangements are driving enterprises to support multiple stacks
- Enterprises have poor technology set management processes and are not optimizing their software portfolio
- The increasing maturity of Xen and Hyper-v are grabbing enetreprise attention and wallet share (fact) but VMware is not being displaced where it exists
My best guess is that the answer is likely to be a combination of 1, 2 and 3. I plan to craft a new question and put it to the readership.
