Google Cloud Digital LeaderDigital transformation with Google CloudHard
A startup is building a new mobile gaming platform that expects extremely high concurrency and requires a globally distributed database with strong consistency to manage player profiles, game states, and in-game transactions. The platform needs to handle millions of read and write operations per second across multiple continents with minimal latency, ensuring that all data is always up-to-date regardless of the user's location. Which Google Cloud database service is designed for these specific requirements?
- ABigQuery
- BCloud SQL
- CCloud Spanner
- DFirestore
Show answer & explanationAnswer & explanation
Correct answer: C. Cloud Spanner
Cloud Spanner is a globally distributed, strongly consistent, and horizontally scalable relational database service. It is uniquely designed to handle millions of transactions per second across continents with low latency, making it ideal for applications like global gaming platforms requiring strong consistency everywhere.
Why the other options are wrong
- A. BigQuery is a data warehouse for analytics, not a transactional database for operational data like player profiles and game states.
- B. Cloud SQL is a regional relational database, offering good scalability but not the global distribution and strong consistency at scale required for this scenario.
- D. Firestore is a NoSQL document database, offering global scalability but eventually consistent by default and often chosen for mobile/web backends with less strict transactional consistency requirements across regions.
Cloud Spanner
Google Cloud's globally distributed, strongly consistent, and horizontally scalable relational database service.
- Offers transactional consistency across regions.
- Scales horizontally to handle massive workloads.
- Combines benefits of relational databases with NoSQL scalability.
Memory trick: Spanner spans the globe with strong, consistent data.
