This recommendation identifies EKS clusters that are about to be charged on Extended Support charges or already charged to avoid unexpected costs and plan upgrades effectively.The recommendation provides an early detection before you get charged, and by default, is set to be triggered 30 days before the extended support is effective. Using the recommendation preferences, you can tune the configuration and set it to receive a much earlier detection.

Umbrella extracts the exact EKS cluster version using the API (permission should be given as part of our policy per account).

• The algorithm extracts the extended support calendar periodically. Once a month.

• EKS calculation logic.

• EKS extended support release calendar by using the Standard Support Pricing Window field.

• The algorithm then scans each cluster version against the release calendar versions.

  • In case the extended support for this version is going to be applied in the next 30 days a recommendation will be triggered, subjecte to the preferences.
  • In case extended support is already applied a recommendation will be triggered.

• Current Cost/Potintial Savings Calculation:

  • Standard support cost per hour=$0.10
  • Extended support cost per hour=$0.60
  • Extended support savings cost per hour=$0.50
  • Extended support annual cost/savings=$0.50x24x365=$4380

• The recommendation specifies:

  • The current and recommended version.
  • The extended support start date.
  • Additional enrichment fields.

• Days Before Expiration, default 30 days.

Since we can't access AWS using APIs, we rely on the invoice only, hence the recommendation has different behaviour:

• The early notification preference isn't relevant for the GovCloud instances as we don't have the version from the API for early detection, therefore we know only after the extended support is effectlvly being charged.
• Once we detect that there's a cost where Service=EKS and Usage Type like 'extendedSupport' we will trigger a recommendation.
