A company is running an application in the AWS Cloud. The application uses AWS Lambda functions and Amazon Elastic Container Service (Amazon ECS) containers that run with AWS Fargate technology as its primary compute. The load on the application is irregular. The application experiences long periods of no usage, followed by sudden and significant increases and decreases in traffic. The application is write-heavy and stores data in an Amazon Aurora MySQL database. The database runs on an Amazon RDS memory optimized DB instance that is not able to handle the load.
What is the MOST cost-effective way for the company to handle the sudden and significant changes in traffic?

A. Add additional read replicas to the database. Purchase Instance Savings Plans and RDS Reserved Instances.

B. Migrate the database to an Aurora multi-master DB cluster. Purchase Instance Savings Plans.

C. Migrate the database to an Aurora global database. Purchase Compute Savings Plans and RDS Reserved Instances.

D. Migrate the database to Aurora Serverless v1. Purchase Compute Savings Plans.
