Question 84 of 105 | ← Chapter 4

Q279. A company has a web application with sporadic usage patterns. There is heavy usage at the beginning of each month, moderate usage at the start of each week, and unpredictable usage during the week. The application consists of a web server and a MySQL database server running inside the data center. The company would like to move the application to the AWS Cloud, and needs to select a cost-effective database platform that will not require database modifications.Which solution will meet these requirements?

It's a simple, cost-effective option for infrequent, intermittent, or unpredictable workloads."https://aws.amazon.com/rds/aurora/serverless/The question clearly states that it is sporadic. Indeed, it is predictable because we do know when the traffic is low and when it increases. However, I think a serverless solution will better work for this kind of workload as it scales out and in only when it needs --> costs savings.
