What is the recommended solution for a solutions architect to ensure reliable and efficient order processing?
Explanation:
The correct answer is B. When dealing with high traffic scenarios, implementing Amazon SQS is beneficial as it decouples the components of the application. By queueing orders in SQS, you ensure that all incoming orders are stored reliably. Using EC2 instances in an Auto Scaling group behind an Application Load Balancer ensures that the processing capacity can scale automatically based on demand, thereby efficiently processing the queued orders into the database. This approach helps maintain reliability and efficiency even during high traffic periods.
