The recovery service level (RSL) measures the percentage of operations that would be recovered during a BCDR situation. The recovery point objective (RPO) sets and defines the amount of data an organization must have available or accessible to reach the determined level of operations necessary during a BCDR situation.

A reservation guarantees to a cloud customer that they will have access to a minimal level of resources to run their systems, which will help mitigate against DoS attacks or systems that consume high levels of resources.
