ServiceNow operates on an Advanced High Availability (AHA) architecture.
* Responsibility: The management of this architecture, including data replication and disaster recovery, is the sole responsibility of ServiceNow .
* The Process: In the event of a catastrophic failure at a primary data center, ServiceNow operations teams are responsible for executing the failover procedures to shift traffic to the paired secondary data center. This is a managed service; the customer does not have buttons or controls to switch data centers themselves.
Reference:
ServiceNow " High Availability and Disaster Recovery " documentation verifies that ServiceNow manages the failover process to ensure business continuity.
