A data analytics team needs a highly scalable and durable object storage solution for raw sensor data that will be continuously ingested and periodically analyzed. The data needs to be readily available for analysis. Which Google Cloud storage service is the most appropriate?
- ACloud Storage
- BCloud SQL
- CPersistent Disk
- DFilestore
Show answer & explanationAnswer & explanation
Correct answer: A. Cloud Storage
Cloud Storage is a highly scalable, durable, and cost-effective object storage service suitable for storing large amounts of unstructured data like raw sensor data. It supports continuous ingestion and provides immediate access for analysis.
Why the other options are wrong
- B. Cloud SQL is a relational database service, not suitable for storing raw, unstructured sensor data at petabyte scale.
- C. Persistent Disk is block storage for Compute Engine VMs and is not designed for independent, highly scalable object storage or continuous ingestion of sensor data.
- D. Filestore provides managed network-attached storage (NAS) for file-based workloads, not ideal for object storage of raw sensor data.
Google Cloud Storage
A highly scalable and durable object storage service for various data types, from frequently accessed to long-term archives. It's ideal for unstructured data, backups, and large-scale data lakes.
- Object storage (not file or block).
- Global, highly durable, and available.
- Scales infinitely.
- Different storage classes for cost optimization.
Memory trick: Cloud Storage holds all your objects, big and small, without a wall.
