A workload needs millisecond reads at any scale on a key-value access pattern with predictable throughput. Which AWS service fits?
AAWS Storage Gateway
BAmazon Athena
CAmazon Redshift
DAmazon DynamoDB (with on-demand or provisioned capacity)
Answer & Solution
Correct answer: D. Amazon DynamoDB (with on-demand or provisioned capacity)
DynamoDB serves single-digit-ms reads and writes for key-value access; provisioned or on-demand capacity. Redshift is a column-oriented data warehouse (analytics not OLTP). Athena queries S3 with SQL. Storage Gateway bridges on-prem to AWS storage.
