I've been looking at this a lot, for ourselves (multitenant saas app running on gcp) and for our customers, who are starting to be curious about something between fully self-managed (too costly) and centralized/multi-tenant/american cloud.
One thing that strikes me is the relationship with architecture. A monolithic, vertically scaled app can run ANYWHERE where I can rent a VM, whether in Norway with Upcloud or on a VPS in Kenya. It's only when you start stitching together managed DBs with autoscaled instance pools etc that vendor lock in begins.
All of these nice toys make our service highly available. But while the overall risk is lower, it is far more correlated between customers. If our service would go down because of a political event, it would go down for all our customers at once.
What about a control plane that manages a fleet of per-customer VMs across an array of cloud providers? Has anyone ever tried this?
