Question

A company has an application that processes customer orders. The company hosts the application on an Amazon EC2 instance that saves the orders to an Amazon Aurora database. Occasionally when traffic is high the workload does not process orders fast enough. What should a solutions architect do to write the orders reliably to the database as quickly as possible?

Accepted Answer

Correct answer: B. The correct answer is B. Option B: Write orders to an Amazon Simple Queue Service (Amazon SQS) queue. Use EC2 instances in an Auto Scaling group behind an Application Load Balancer to read from the SQS queue and process orders into the database. Auto Scaling adjusts capacity automatically to match demand, improving availability and cost efficiency. Amazon EC2 provides resizable virtual servers when you need full control of the operating system. An Application Load Balancer distributes HTTP/HTTPS traffic and supports path/host routing.
