Amazon RDS for MySQL is the best answer because it offers a managed relational database service that provides a similar MySQL experience as the company's on-premises databases do. It reduces the operational overhead by handling routine database tasks such as provisioning, patching, backup, recovery, failure detection, and repair. Moreover, it's cost-effective for workloads that do not require the high performance or advanced features provided by other solutions like Amazon Aurora, which can be more expensive due to its enhanced performance capabilities.
