An online retail corporation requires its e-commerce platform to sustain high availability and resist service disruptions from geographical incidents. The platform is currently experiencing increased customer activity and requires a configuration that mitigates disturbances while preserving transactional integrity in the face of data center outages. What architectural enhancement should be made to reduce the impact of such disruptions on the platform's operation?
Extend the platform's presence to multiple geographic locations with data storage replication across these localities.
Optimize the existing infrastructure within one location with redundant power and networking to ensure uninterrupted service.
Implement a dynamic scaling service to automatically adjust resources in response to changing customer activity.
Arrange for additional standby instances within the current operating area for manual switching during incidences.
