City auditors run ad-hoc full-text searches across years of application logs stored in the same Amazon RDS instance that serves online permitting transactions, causing lock and I/O contention. Which managed-service adoption best improves performance fit?
Select an answer to reveal the explanation.
Short Explanation
Do not ask the cash register to also be the library catalog. Keep permitting OLTP on RDS and give auditors a purpose-built OpenSearch index so those heavy text hunts stop punching the transaction lane.
Full Explanation
Purpose-built services improve fit: OpenSearch is designed for log and full-text search workloads that stress relational OLTP engines. Separating search from the permitting primary reduces contention. ElastiCache is not durable log storage, and tape-only workflows abandon interactive audit needs. Simply growing RDS storage does not fix inappropriate query patterns on the writer.
