I would recommend that you consider Lunavi. www.lunavi.com
It all depends on your company structure. And it does depend on your workload as well.
I do keep my workloads up and working well in their infrastructure. They have private-clouds, they have public-clouds, and they have my cloud.
I use their private cloud for all of my crical services. As an engineering company that is always on, they always keep the services up. They have migrated it a few
times, and the downtime was always in sub-millisecond.
I have been known to call them late at night. They do take care of things.
We are just living in an era that is so focused on the cloud. Nobody gets pissed if an amazon hypervisor shuts down. Yet the technology has been there for 20 years to keep that from shutting down.
I've done this off and on for the better part of two decades. I know a few good colo's across the US if your interested.
Much of it is going to depend on your workloads. If your just running emepheral vm's on something like vmware or another hypervisor, you won't run into much of a problem.
Things start getting a bit more complicated if you are going to be using HA storage/databases. But again, that depends on your workload. And some datacenters will be happy to manage that for you.
There is alot of money that can be saved when your workloads are fairly static though. The key is putting together some hardware automation (jumpstart your hypervisors) and handling the depreciation cycle.
