A User Owns a MySQL Database That Is Accessed by Various

Multiple Choice

A user owns a MySQL database that is accessed by various clients who expect, at most, 100 ms latency on requests. Once a record is stored in the database, it is rarely changed. Clients only access one record at a time. Database access has been increasing exponentially due to increased client demand. The resultant load will soon exceed the capacity of the most expensive hardware available for purchase. The user wants to migrate to AWS, and is willing to change database systems. Which service would alleviate the database load issue and offer virtually unlimited scalability for the future?

A) Amazon RDS
B) Amazon DynamoDB
C) Amazon Redshift
D) AWS Data Pipeline
