Google Cloud Spanner is a fully managed relational database service. The service allows you to deploy mission critical databases and offers transactional consistency globally, along with automatic synchronous replication for high availability. Cloud spanner is ideal for mission critical databases that require replication and strong transactional consistency. This logo represents Google Cloud Spanner:
Cloud spanner databases are replicated synchronously; this is done at a global scale. The underlying operating system that powers cloud spanner has the ability to synchronously replicate at a byte level. Cloud spanner stores the databases as a bunch of files and the filesystem takes care of replicating these files across multiple regions. Cloud spanner stores all data as rows and replicates these rows on to multiple regions for high availability.
