A global product catalog stores JSON with varying attributes and needs low-latency regional reads with customer read-your-own-write behavior. Which starting architecture fits?

Choose the single best answer.

A.Blob archive for all operational documents with immediate reads
B.Azure Files with row-level SQL constraints
C.Cosmos DB for NoSQL with an access-aligned distributed key, appropriate regions, and session handling
D.Azure Table storage assumed to provide every Cosmos regional and consistency feature

Show the answer and explanation

✓ Correct answer

Cosmos DB for NoSQL with an access-aligned distributed key, appropriate regions, and session handling

Cosmos NoSQL fits the document/operational/regional pattern, with session tokens for session guarantees. Files and archive do not satisfy those query semantics. Table does not inherit the entire Cosmos feature matrix. Source guide: PDF page 30-31.
