You need to evaluate the service development requirements to ensure that the number of vCPUs of an ECS is sufficient for service growth and prevent service interruption caused by insufficient specifications.

Solution

Scale up vCPUs and memory of your ECSs to meet service requirements. Certain ECSs support changing ECS types. For details, see Modifying Specifications of Individual ECSs.

Rule Logic

  • If an ECS has fewer vCPUs than required, the check result is non-compliant.
  • If an ECS has vCPUs greater than or equal to the required, the check result is compliant.
