Selected Answer: D

Cloud SQL: max storage for shared core = 3TB and for dedicated core = up to 64TB Only use Spanner if we need autoscale (Note that Cloud SQL could scale too but not automatic yet) or the size is too big (as above) or 4/5 9s HA (Cloud SQL is only 99.95)

But cloud SQL storage is limited to several hundreds of GB's for all instances and we need 2TB. So, Cloud spanner is much closer to this, with the exception of the cost

At this moment, Cloud SQL is providing up to 30,720GB(about 30TB) So I think it's D.

Another consideration is that Cloud SQL uses standard databases like MySQL, PostgreSQL and now MS SQL. Cloud Spanner is a proprietary product of Google and does some things differently than typical databases (no stored procedures and triggers). So migrating to Cloud Spanner makes application refactoring necessary. So Cloud SQL is the answer.
