Bottom Line:

Google Cloud Spanner has a good reputation for managing large volumes of data, dealing with repetitive queries, and ease of deployment. Cloud Spanner is good for traditional transactions and and analytics, as well as geographically diverse databases. 

Cloud Spanner is one of several DBaaS offerings from Google, so potential customers can rest assured: Google understands the needs of the database market.

Existing Google Cloud Platform (GCP) customers will be drawn to this product, as well as those already using tools from close partners like Cisco, NetApp, Salesforce and SAP. These partnerships afford it a great many integration and implementation advantages. But those already committed to Oracle, Amazon and Microsoft are unlikely to be swayed.


Google Cloud Spanner is an enterprise-grade, globally distributed database service built for the cloud that combines the benefits of relational database structure with non-relational horizontal scale. It offers 99.999% availability, no planned downtime, and enterprise security. It is said to make development more efficient. The newest version has enhanced query introspection, adds new regions, and includes multi-region configurations.

Cloud Spanner scales horizontally and serves data with low latency. It can scale to large database sizes to avoid rewrites and migrations. It is used inside Google for its own mission-critical applications and services. Implementation is relatively simple. Select or create a GCP project with billing enabled, create an instance and then create a DB and a schema.
