No-Compromise Relational Database Service

Cloud Spanner is the first and only relational database service that is both strongly consistent and horizontally scalable. With Cloud Spanner you enjoy all the traditional benefits of a relational database: ACID transactions, relational schemas (and schema changes without downtime), SQL queries, high performance, and high availability. But unlike any other relational database service, Cloud Spanner scales horizontally, to hundreds or thousands of servers, so it can handle the highest of transactional workloads. With automatic scaling, synchronous data replication, and node redundancy, Cloud Spanner delivers up to 99.999% (five 9s) availability for your mission-critical applications. In fact, Google’s internal Spanner service has been handling millions of queries per second from many Google services for years.

Strong Consistency, Scale and Performance

Never trade off between scale and consistency again. Cloud Spanner scales horizontally within regions (expanding to cross-region replication later in 2017), and serves data with single-digit millisecond latencies, while maintaining transactional consistency and up to 99.999% (five 9s) availability. Scale out your RDBMS solutions without complex sharding or clustering.

Maximize Business Uptime

Global, automatic, synchronous replication with low latency ensures your data is highly available and consistent. Battle tested by Google’s own mission-critical applications and services, Spanner powers Google’s $80 billion business.

Focus On Your Application, Not Infrastructure

Use your IT resources to focus on your application logic instead of spending valuable time managing hardware and software. Fully managed and built for the cloud, Cloud Spanner’s automatic sharding and synchronous replication guarantee high availability for applications without the need for you to engineer a complex replication and failover infrastructure.

Comprehensive Security And Control

Google-grade security includes encryption by default in transit and at rest, granular identity & access management, comprehensive audit logging, custom-manufactured hardware, hardware tracking and disposal, and the Google-owned and controlled global network.

“Cloud Spanner presents tremendous value for our customers who are retailers, manufacturers and wholesale distributors around the world. With its ease of provisioning and scalability, it will accelerate our ability to bring cloud-based omni-channel supply chain solutions to our users around the world.”

- John Sarvari Group Vice President, Technology, JDA

“Based on our experience and performance testing, Cloud Spanner is the most compelling option we’ve seen to power a high-scale relational query workload. It has the performance and scalability of a NoSQL database, but can execute SQL so it’s a viable alternative to sharded MySQL. It’s an impressive technology and could dramatically simplify how we manage our databases.”

- Peter Bakkum Platform Lead, Quizlet
