Begin with a zonal instance of Cloud SQL for PostgreSQL, then transition to Cloud Spanner after securing funding.
B
Start with a highly available instance of Cloud SQL for PostgreSQL, then switch to Bigtable with replication across US, Europe, and Asia post-funding.
C
Configure a single region instance of Cloud Spanner initially, then expand to multi-region Cloud Spanner instances after securing funding.
D
Initiate with a zonal instance of Cloud SQL for PostgreSQL, then upgrade to a highly available configuration of Cloud SQL for PostgreSQL after funding.
