They already run on gcp and presumably have a negotiated agreement on pricing. Their core competencies don’t include managing hardware. Migration off is deliberately expensive and hard. Own hardware still needs a story for backup and restore in lieu of attached volume snapshots, or they’d have to figure out if their database can do something for them there. Any of the above are good reasons to not migrate willy nilly, in fact the only reason to migrate is that either you can’t do what you need to in the cloud or the margins can’t support it.
