A startup is building a new mobile backend that requires a highly scalable, fully managed NoSQL database capable of handling millions of requests per second with single-digit millisecond latency. The data model is flexible and requires strong consistency. Which Google Cloud product is the most appropriate choice for this scenario?
- AFirestore
- BCloud SQL
- CCloud Spanner
- DBigQuery
Show answer & explanationAnswer & explanation
Correct answer: A. Firestore
Firestore is a NoSQL document database built for mobile, web, and server development. It offers automatic scaling, strong consistency, and real-time data synchronization, making it ideal for applications requiring high throughput and low latency like a mobile backend.
Why the other options are wrong
- B. Cloud SQL is a relational database, not NoSQL, and while scalable, it's not designed for millions of requests per second with single-digit millisecond latency for flexible data models.
- C. Cloud Spanner is a globally distributed relational database, offering strong consistency and high availability, but it's relational, not NoSQL, and often overkill for typical mobile backends needing flexible schemas.
- D. BigQuery is an analytical data warehouse, not an operational NoSQL database for application backends.
