Now we are on the sixth topic: Cloud Spanner. Cloud Spanner is a fully managed, mission-critical, and relational database service that offers transactional consistency at a global scale, schemas, SQL, and automatic synchronous replication for high availability.
Cloud Spanner offers:
- Strong consistency
- SQL support
- Managed instances with high availability through transparent, synchronous, and built-in data replication
- Regional and multi-regional instance configurations
Cloud Spanner is ideal for relational, structured, and semi-structured data that requires high availability, strong consistency, and transactional reads and writes. In most cases, Cloud SQL would suffice your requirement, but Cloud Spanner can be a real savior when we are talking about consistency and high availability.
