is hybrid cloud a fundamental for your organisation?
"The cloud" is really just marketing speak for hosting software on someone else's hardware, and in that sense then yes, it's a fundamental part of our organisation.
Most of our server estate sits as VMs on privately hosted virtual environments in various datacenters run by various suppliers.
The things we retain as on-premises are what's needed to make the office work, so we have Active Directory DCs, Exchange servers, file servers, and software repositories as either physical or virtual machines hosted in our own buildings.
Does this count as "hybrid cloud"?
I doubt it.
