Question

Raeed H · Accepted Answer

Maybe if the instance is running slow or the demand is increasing or decreasing. You may need to vertically scale it

Sakthivel B · Answer

You can determine if your EC2 instance needs vertical scaling by monitoring the following metrics in Amazon CloudWatch: High CPU utilization over a sustained period (e.g., >80%) High memory usage (requires custom metrics, as EC2 doesn’t report memory by default) Frequent application slowdowns or timeouts Disk or network I/O bottlenecks Consistently high load average compared to the number of vCPUs If these signs persist, upgrading to a larger instance type (more CPU, memory, or network throughput) may be necessary.
