We have servicing contracts with all parts of our infrastructure, but with HyperFlex you typically only need one person to manage aspects such as implementation and configuration. It does not need much in the way of maintenance, which makes working with it very easy. The one problem we have, though, is that when you have 20-50 VMs and you want to do updates for either HyperFlex or VMware, there's usually a bit of extra work to do in this process, not knowing whether your interventions or updates will cause problems. But overall, it's easy, and I would rate HyperFlex's stability a ten out of ten.
