There appears to be a challenger to â€˜VM sprawlâ€™ as the scourge of virtualization success – a problem I call â€˜VM stallâ€™.
We know about â€˜VM sprawlâ€™ â€“ because new virtual machines are so easy to deploy, organizations can end up with more VMs that they can handle, or even use. This has the potential to cause severe problems to availability, performance, compliance, costs, security, and more.
However, I am seeing more and more evidence of this new phenomenon I think of as â€˜VM stallâ€™ â€“ the tendency for virtualization deployments to stall once the â€˜low-hanging fruitâ€™ has been converted (typically around 20-30% of servers).
I think it happens more or less like this…
