It's almost certainly not the case that Gmail uses Cloud Spanner rather than Internal Spanner. I don't think Cloud Spanner (or most of Google's cloud products) have the featureset required to support loads like Gmail (both in terms of technical capability, and security/privacy features).
When I worked at Google I tried to get more services to migrate to the cloud but the internal environment that was built up over 25 years is much better at supporting billion+ users with private data.

After all, isn't that also how AWS started, just reselling the services and servers they already use themselves? It doesn't make much sense to have a 'better' version of a product you sell but keep it internal.
- jeffbee 3y agoIt makes sense because the public will not use the internal APIs which have non-standard wire protocols, weird authentication schemes, etc.
