A cloud administrator notices users call to report application performance degradation between 1:00 p.m. and 3:00 p.m. every day. Which of the following is the BEST option for the administrator to configure?
Auto-scaling is a feature that helps to adjust the capacity of a system automatically based on its current demand. The goal of auto-scaling is to maintain the performance of the system and to reduce costs by only using the resources that are actually needed1. If the cloud administrator configures auto-scaling for the application, the system can scale out (add more instances) during the peak hours of 1:00 p.m. and 3:00 p.m. every day, and scale in (remove instances) when the demand is low. This way, the application can handle the increased workload without degrading its performance, and the users can have a better experience.
