Question: Firebase is GCP's mobile extension. Several of Firebase’s products are built on top of GCP products, providing mobile-optimized SDKs and capabilities. Which of these products can be amplified via Firebase?
- Cloud SQL
- Cloud Engine
- Cloud Spanner
- Cloud Storage
Explanation
Cloud Storage for Firebase stores app files in a Cloud Storage bucket and exposes them through Firebase SDKs. This lets mobile and web apps upload and download user-generated content such as photos and videos. The Firebase integration adds mobile-optimized access while still using Google Cloud storage infrastructure. This makes Cloud Storage the Google Cloud product that can be extended through Firebase.
Why the other options are incorrect
Cloud SQL is a managed relational database service, not the Firebase-amplified storage product.
Cloud Engine is not the official name of the Google Cloud compute product.
Cloud Spanner is a globally distributed relational database, not the Firebase storage integration.
