Ensure number of instances are not close to the Account Instance Limit


Checks if the number of EC2 instances in your AWS account has reached the threshold established by your organization for the workload deployed. Monitoring and setting limits for the maximum number of EC2 instances provisioned in your AWS account will help you to manage better your compute power and prevent unexpected charges on your AWS bill in case of auto-scaling misconfiguration or large DDOS attacks.
