Cloud Spanner as a Managed Service
In this topic you will explore how cloud spanner can be leveraged as a managed service as with cloud SQL cloud spanner is a line to relational database requirements. The key difference is that cloud spanner combines the benefits of relational database structure with non-relational horizontal scale. Vertical scaling is where you make a single instance larger or smaller horizontal scaling is when your skin by adding or removing service. What makes cloud spanner unique is that it’s a relational database that scales horizontally cloud spanner users are often in advertising finance and marketing technology industries where the need exists to manage and use a metadata. Most databases today require making trade-offs between scale and consistency the cloud spanner you get the best of relational database structure and non-relational database scale and performance with strong external consistency across Rose regions continents. This means clouds spanner can scale two very large database sizes while still giving IT and developers that familiarity they are used to with other relational databases such as MySQL source receivable or proprietary databases. Cloud spanner is strongly consistent, data added or updated from any location is immediately available regardless of the location and is accessed. Cloud spanner also dramatically reduces the operational overhead needed to keep the database online and some in traffic. Users often move to Cloud spanner from Charlotte MySQL deployments and expensive proprietary solutions. Cloud spanner horizontally and serves data with low latency while maintaining transactional consistency and industry-leading 5/9 availability which is less than 5 minutes sound time for ear. Cloud spanner can scale to arbitrary large database sizes to help avoid rewrites and migrations, the use of multiple databases or shorter databases as an alternative solution introduces unnecessary complexity and cost cloud spanner allows you to create or scale of globally replicated database for mission-critical apps through a handful of clicks single replication and maintenance are also automatic and built in. Cloud spanner is a relational database with full relational semantics acid transactions and handled schema changes as an online operation with no planed down time. You can reuse existing SQL skills to query data and cloud spanner using familiar industry-standard and see 2011 SQL. Enterprise-grade security includes data encryption by default in transit and at rest granular identity and access management and audit logging. So how does cloud spanner work with data is automatically and instantly copied across regions this is called synchronous replication as a result queries is always written consistent and ordered answers regardless of the region. Google uses replication within and across regions to achieve availability so if one region goes offline your data can still be sold from another region
