A company is migrating a legacy application to AWS. The application requires a relational database. The database will be used sporadically, with long periods of inactivity followed by short bursts of high CPU utilization. The company wants to minimize costs. Which database service should be used?

Answer options:

Amazon RDS for MySQL

Amazon Aurora Provisioned

Amazon Aurora Serverless

Amazon Redshift

How to approach this question

Match 'relational database', 'sporadic usage', and 'minimize costs' with Aurora Serverless.

Full Answer

C.Amazon Aurora Serverless✓ Correct

Amazon Aurora Serverless

Amazon Aurora Serverless is an on-demand, auto-scaling configuration for Amazon Aurora. It is the most cost-effective option for infrequent, intermittent, or unpredictable workloads because it automatically scales capacity up or down based on application needs, and you only pay for the database capacity you consume.

Common mistakes

Choosing standard RDS, which incurs costs even when idle.
