Relational database, built for scale

Everything you would expect from a relational database—schemas, SQL queries, and ACID transactions—battle tested and ready to scale globally.

High availability

Cloud Spanner delivers industry-leading high availability (99.999%) for multi-regional instances—10x less downtime than four nines—and provides transparent, synchronous replication across region and multi-region configurations.

Automatic database sharding

Cloud Spanner optimizes performance by automatically sharding the data based on request load and size of the data. As a result, you can spend less time worrying about how to scale your database and instead focus on scaling your business.

Use case
Develop global multiplayer games with Spanner

Spanner is a distributed, globally scalable SQL database service that decouples compute from storage, which makes it possible to scale processing resources separately from storage. This distributed scaling nature of Spanner’s architecture makes it an ideal solution for unpredictable workloads such as online games. Learn how to get started developing global multiplayer games using Spanner, in this whitepaper.

Observability Monitor performance of Spanner databases with metrics and stats. Analyze usage patterns in Spanner databases with Key Visualizer, an interactive monitoring tool. Use Query Insights for visualizing query performance metrics and debugging issues in the Google Cloud console.



Pricing for Spanner is simple and predictable. You are only charged for the compute capacity of your instance (as measured in number of nodes or processing units), the amount of storage that your database's tables and secondary indexes use (not pre-provisioned), backup storage, and the amount of network egress. Note that there is no additional charge for replication of data between zones or regions in an instance. See the pricing guide for more details.
