Measured service means that costs are only incurred when a cloud customer is actually using cloud services.
This is ideal for a business continuity and disaster recovery (BCDR) solution because it negates the need to keep hardware or resources on standby in case of a disaster. Services can be initiated when needed and without costs unless needed.

The correct sequence for a BCDR plan is to define the scope, gather requirements based on the scope, assess overall risk, and implement the plan. The other sequences provided are not in the correct order.
