1. A financial institution operates two data centers simultaneously. Both handle real production transactions at all times. When one data center experiences a power failure, the other continues serving all customers without any service interruption — it was already handling half the load and simply absorbs the remainder
2. An organization rents a facility in another state that has rack space and basic network connectivity, but no servers or data currently installed. In the event of a disaster, they plan to transport servers from a secondary storage location, restore data from cloud backups, and have the site operational within 12 hours
3. A company distributes critical data and services across both AWS and Microsoft Azure, so that if one cloud provider experiences a major outage, the other provider's services remain fully operational
4. A hospital creates paper forms for manual patient registration, printed directories with all department phone numbers, and a binder of procedures for manually routing medication orders — all stored physically at nursing stations — to be used if electronic systems become unavailable
