An application running on Amazon EC2 has been experiencing performance issues when accessing an Amazon RDS for Oracle database. The database has been provisioned correctly for average workloads, but there are several usage spikes each day that have saturated the database, causing the application to time out. The application is write-heavy, updating information more often than reading information. A Solutions Architect has been asked to review the application design.
What should the Solutions Architect recommend to improve performance?
A. Put an Amazon ElastiCache cluster in front of the database and use lazy loading to limit database access during peak periods.
B. Put an Amazon Elasticsearch domain in front of the database and use a Write-Through cache to reduce database access during peak periods.
C. Configure an Amazon RDS Auto Scaling group to automatically scale the RDS instance during load spikes.
D. Change the Amazon RDS instance storage type from General Purpose SSD to provisioned IOPS SSD.
