As an example, you might create a Business Critical resource group that consists of high-performance hosts intended for mission critical applications and services. You assign the resource group a Platinum service level with costs that reflect the more expensive hardware and service contract. Any business service that is provisioned to the resource group’s hosts automatically inherits the resource and service costs.
Or, you might create a Lab resource group that consists of standard-performance hosts intended for software testing. You assign the resource group a Bronze service level with costs that reflect the less expensive hardware and service contract.
