Center 

  • Used to help facilitate automated billing via the Cornell KFS system.
  • Any AWS resource with that tag will be billed directly to the provided account number.
  • Anything in a Cornell AWS account that is not tagged (or cannot be tagged) will be billed to the Cornell account number associated with the AWS account as a whole. 
  • Note that applying the cost_center "Cost Center" tag to a resource does not retroactively adjust the billing data for the resource, prior to the tag being set. E.g., If you have an EC2 instance running 24/7 and you set the cost_center tag "Cost Center" tag for that instance on the 15th day of the billing period, the cost_center "Cost Center" will be billed the cost of the EC2 instance starting from that day forward.

    • Under this scheme, the parts of the accounting string labeled as optional in the link above can be left off, but a total of six hyphens are required.
