The company I work for used to have a hybrid where 95% was on-prem, but became closer to 90% in the cloud when it became more expensive to do on-prem because of VMware licensing. There are alternatives to VMware, but not officially supported with our hardware configuration, so the switch requires changing all the hardware, which still drives it higher than the cloud. Almost everything we have is cloud agnostic, and for anything that requires resilience, it sits in two different providers.

Now the company is looking at doing further cost savings as the buildings rented for running on-prem are sitting mostly unused, but also the prices of buildings have gone up in recent years, notably too, so we're likely to be saving money moving into the cloud. This is likely to make the cloud transition permanent.
