Hard to move
Spanner on Hetzner (US): what it becomes and what it costs.
On Hetzner (US), Spanner becomes CockroachDB or YugabyteDB. Globally consistent SQL has open-source analogues but migration is a project.
Effort grade
Hard
No equivalent: redesign it, buy a SaaS, or leave it where it is
Cost after the move, before engineer time
50% of today
No like-for-like product; the rebuilt replacement (open-source stack on a server or two) typically lands at 50% of today's spend, excluding the rebuild itself.
Engineer time
16 h a month
To run the replacement: patching, backups, on-call. Plus about 15 engineer days for the move itself.
