[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A company is migrating a three-tier application to AWS. The application requires a MySQL database. In the past, the application users reported poor application performance when creating new entries. These performance issues were caused by users generating different real-time reports from the application during working hours.

Which solution will improve the performance of the application when it is moved to AWS?

  • A. Import the data into an Amazon DynamoDB table with provisioned capacity. Refactor the application to use DynamoDB for reports.
  • B. Create the database on a compute optimized Amazon EC2 instance. Ensure compute resources exceed the on-premises database.
  • C. Create an Amazon Aurora MySQL Multi-AZ DB cluster with multiple read replicas. Configure the application to use the reader endpoint for reports.
  • D. Create an Amazon Aurora MySQL Multi-AZ DB cluster. Configure the application to use the backup instance of the cluster as an endpoint for the reports.

Selected Answer: C
Answer C Any replica of Amazon Aurora Db will be read-only replica (even backup one). Option C is better then D because we will use multiple replicas which when used will signicially allow to increase performance for creating reports. In the same time no write operation should be affected. https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/AuroraMySQL.Replication.html
