Migrate the MySQL database to Amazon RDS, replicate the web application with an AMI, and deploy a second EC2 instance with an Application Load Balancer for load distribution.
B
Shift the MySQL database to Amazon RDS, use an AMI for the web application, launch an additional EC2 instance, and balance the load with Amazon Route 53 weighted routing.
C
Upgrade the MySQL database to Amazon Aurora, develop a Lambda function to adjust EC2 instance type upon high CPU utilization, and set an Amazon CloudWatch alarm to trigger this function at 75% CPU usage.
D
Transfer the MySQL database to Amazon Aurora, use an AMI for the web application in a launch template, establish an Auto Scaling group with a Spot Fleet, and connect it to an Application Load Balancer.
