You are responsible for deploying an application on Oracle Cloud Infrastructure (OCI).
The application is memory intensive, and will perform badly if not enough memory is available.
You have created an instance pool of Linux compute instances in OCI to host the application, and defined an Autoscaling Configuration for the instance pool.
What should you do to ensure that the instance pool autoscales to prevent poor application performance?
To ensure the instance pool autoscales appropriately for a memory-intensive application, it is essential to monitor resource usage that directly impacts the performance. Although configuring an autoscaling policy specifically for memory usage might seem intuitive, Oracle Cloud Infrastructure currently supports autoscaling based on metrics such as CPU utilization. Therefore, configuring the autoscaling policy to monitor CPU usage and scale up the number of instances when the CPU usage meets the threshold is the most applicable approach to indirectly ensuring adequate performance for memory-intensive applications.
D. Configure the autoscaling policy to monitor memory usage and scale up the number of instances when it meets the threshold.
I am choosing C because of this https://docs.oracle.com/en/learn/configure_auto_scaling/index.html#introduction
I agree with D. Configure the autoscaling policy to monitor memory usage and scale up the number of instances when it meets the threshold. Memory utilization can be a metric for autoscaling policy https://docs.oracle.com/en-us/iaas/Content/Compute/References/computemetrics.htm#Compute_Instance_Metrics
I agree with D.
