Which combination correctly maps each public cloud's managed NoSQL key-value service?
AAWS DynamoDB / Azure Cosmos DB / GCP Firestore (or Cloud Bigtable for wide-column)
BAWS Lambda / Azure Functions / GCP Cloud Run
CAWS RDS / Azure SQL / GCP Cloud SQL
DAWS S3 / Azure Storage Account / GCP Spanner
Answer & Solution
Correct answer: A. AWS DynamoDB / Azure Cosmos DB / GCP Firestore (or Cloud Bigtable for wide-column)
DynamoDB, Cosmos DB (with its various APIs), and Firestore are the canonical managed NoSQL document/KV services. The other mappings are object storage, serverless compute, and managed relational — different categories.
