A financial services company is migrating its on-premises data warehouse to Google Cloud. The current data warehouse is several petabytes in size and requires complex SQL queries for reporting and analytics. The company needs a highly scalable, fully managed, and cost-effective solution that can handle massive datasets and allow for rapid query execution. Which Google Cloud product is the best fit for these requirements?
- ACloud SQL
- BBigQuery
- CCloud Storage
- DCloud Spanner
Show answer & explanationAnswer & explanation
Correct answer: B. BigQuery
BigQuery is a serverless, highly scalable, and cost-effective enterprise data warehouse designed for petabyte-scale analytics, making it ideal for complex SQL queries on large datasets.
Why the other options are wrong
- A. Cloud SQL is a relational database service for smaller to medium-sized datasets, not optimized for petabyte-scale data warehousing.
- C. Cloud Storage is an object storage service, suitable for storing raw data but not for directly running complex SQL queries as a data warehouse.
- D. Cloud Spanner is a globally distributed, strongly consistent database for transactional workloads, not primarily a data warehouse for analytics.
