A company has an ecommerce application that stores data in an on-premises SQL database. The company has decided to migrate this database to AWS.
However, as part of the migration, the company wants to find a way to attain sub-millisecond responses to common read requests.

A. Build Amazon RDS read replicas. B. Build the database as a larger instance type. C. Build a database cache using Amazon ElastiCache. D. Build a database cache using Amazon Elasticsearch Service (Amazon ES).
