An e-commerce company experiences consistent weekend traffic surges lasting about 4 hours. Which AWS service can they use to automatically scale EC2 instances to handle increased demand?
Explanation:
The correct answer is D, Amazon EC2 Auto Scaling. This service allows the company to automatically adjust the number of EC2 instances in response to changes in demand, ensuring that there are enough instances to handle the surges in traffic that occur every weekend. By creating a schedule or using CloudWatch Alarms, the company can increase the number of instances before the surge and decrease them afterward, maintaining application availability and optimizing costs.
