I posed the question about why readers of the hot aisle were running more than one hypervisor. An earlier poll had shown that 44% of respondants behave in a non-intuitive way and run two or more hypervisors.
Early results are in – with a poll size of 1021 1141 readers and discounting those who only use one hypervisor:
- 48% do so because of vendor pressure
- 26% do so because they allow different groups to do their own thing
- 12% like the single vendor support model
- 6% want to avoid licence fees and like the open source model
- 4% can’t support all of their software on one hypervisor
- 2% think that they need to move for technical reasons
Here is my take:
- Technology differences are irrelevant
- Licence costs aren’t that important
- Compatibility isn’t that relevant
- Risk and application support are the main drivers for hypervisor adoption
- Some organisations need to get their act together in technology set management!
I think the poll shows that 60% of respondants choose to support more than one hypervisor because their software vendor tells them to (some like it, some hate it). This reflects what we all knew all along – content is king in the long term.
This will have significance for all of the vendors.
- Citrix and VMware need to work to get ISV support and lock in (as will Microsoft and Oracle)
- Microsoft and Oracle need to explain better the benefits of their single stack support model
- Running multiple hypervisors is a reality and we now need the glue and support to make this easier
