For this question, refer to the EHR Healthcare case study.
EHR Healthcare wants to create a single, globally accessible, high-performance SQL transactional database that provides EHRs to all customers with minimal latency and allows their management.
Insurance providers will provide and access data globally.
Which service do you think is the best?
A. Cloud Spanner
B. Cloud SQL with MySQL and global Read Replicas
C. Cloud SQL with SQL Server and global Read Replicas
D. Firestore replicated in multiple regions
Correct answer: A
Cloud Spanner is a fully managed, globally distributed, ACID-compliant relational database with read-write unlimited scale, strong consistency, and up to 99.999% availability. It handles replicas, sharding, and transaction processing.
- B is wrong because the DB must be globally in read-write mode. In addition Cloud SQL may be a too small solution for a such growing business
- C is wrong also because SQL Server do not support global Read Replicas
- D is wrong because Firestore is not a SQL transactional database
