You are building an application that stores relational data from users. Users across the globe will use this application. Your CTO is concerned about the scaling requirements because the size of the user base is unknown. You need to implement a database solution that can scale with your user growth with minimum configuration changes. Which storage solution should you use?
Given the requirements for a relational database that scales automatically with a potentially global user base, the best storage solution is Cloud Spanner. Cloud Spanner is designed for high availability and durability across global deployments, and it can scale seamlessly with user growth. Additionally, it supports SQL semantics, offering a familiar relational database experience for developers. Other options like Cloud SQL, Cloud Firestore, and Cloud Datastore either do not scale as effectively or are not designed for relational data storage.
B Cloud SQL for small relational data, scaled manually Cloud Spanner for relational data, scaled automatically Cloud Firestore for app-based data(?) Cloud Datastore for non-relational data Correct me if i'm wrong
Just one detail: Cloud Firestore for non relational data (noSql)
N E R D
'small relational data' as in 3 TB for Shared core or 64 TB for Dedicated core in Cloud SQL
in my opinion correct is B
The best storage solution for this scenario would be Cloud Spanner. Cloud Spanner is a fully managed, scalable, relational database that is designed to handle global deployments with ease. It can handle large amounts of data and high transactional volumes. It also provides automatic sharding and synchronous replication, ensuring high availability and durability of data. Cloud Spanner supports SQL semantics and provides a familiar relational database experience to developers, which would make it easy to adopt in existing workflows. Cloud SQL, on the other hand, has limits on scalability and does not support global deployments as well as Cloud Spanner. Cloud Firestore and Cloud Datastore are NoSQL databases that are better suited for document-based data storage and not optimized for relational data storage.
Global is keyword in this question, Cloud Spanner is the right option.. B
Correct ans is B... Focus on two words "Relational" which means option C & D has been eliminated bcz these are non-relational DB.And another word 'Globally' which means Option A also eliminated bcz Cloud Sql does not support global deployments.
B is correct
B. keywords: "global" and "relational"
B is Correct Ans. Cloud Spanner provides a scalable online transaction processing (OLTP) database with high availability and strong consistency at a global scale.
Go for B
B as many have mentioned already
B is correct
Correct answer is B Cloud Firestore and Cloud Datastore - can easily be eliminated doesn't fall under Relational DB
B. Spanner for autoscale
could someone please explain why the answer is not A
correct is B
B, for large and automatically scaled
Cloud spanner is correct as it will scaled automatically
