A company is migrating an on-premises 5TB MySQL database to AWS and expects its database size to increase steadily. Which Amazon RDS engine would meet these requirements?
 

Answer options:

A.MySQL
B.Microsoft SQL Server
C.Oracle
D.Amazon Aurora

Correct Answer – D
AWS Documentation supports the above requirements concerning AWS Aurora.
Amazon Aurora (Aurora) is a fully managed, MySQL and PostgreSQL compatible, relational database engine. It combines the speed and reliability of high-end commercial databases with the simplicity and cost-effectiveness of open-source databases. It delivers up to five times the throughput of MySQL and up to three times the throughput of PostgreSQL without requiring changes to most of your existing applications.
All Aurora Replicas return the same data for query results with minimal replica lag—usually, much lesser than 100 milliseconds after the primary instance has written an update.

NOTE:
On a MySQL DB instance, avoid tables in your database growing too large. Provisioned storage limits restrict the maximum size of a MySQL table file to 16 TB.
However, based on database usage, your Amazon Aurora storage will automatically grow, from the minimum of 10 GB up to 64 TB, in 10 GB increments, with no impact on database performance.
Hence, the best answer would be option
D.
