Resilience is the ability to continue operating under adverse or unexpected conditions. This involves both business continuity and disaster recovery planning and implementation. Business continuity might dictate that a customer stores their data in multiple regions so that a service interruption in one region does not prevent continued operations.

The cloud also provides resiliency when a customer suffers a severe incident such as weather, facilities damage, terrorism, civil unrest, or similar events. A cloud strategy allows the company to continue to operate during and after these incidents. The plan may require movement of personnel or contracting personnel at a new location. The cloud strategy handles the data and processes as these remain available anywhere network connectivity exists.

Major CSPs use multiple regions and redundancy to increase the ability of a recovery. Many organizations plan a resilient strategy that includes internal resources and the capabilities of the cloud.
