A stock trading company had the budget for enhancing its secondary datacenter approved. Since the main site is a hurricane-affected area and the disaster recovery site is 100 mi (161 km) away, the…

A hot site requires substantial upfront investment and ongoing operational man-hours to maintain duplicate physical infrastructure and ensure real-time replication, which contradicts the goal of minimizing man-hours.

A warm site requires some manual intervention, hardware setup, and data restoration during a disaster, leading to a noticeable downtime that does not align with the requirement for the business to be 'always operational'.

A cold site offers only basic infrastructure and demands extensive time for hardware procurement, installation, and data restoration after a disaster, resulting in the longest downtime and failing the 'always operational' requirement.

A cloud-based site leverages cloud provider infrastructure and managed services, such as Azure Site Recovery, to deliver near-zero Recovery Time Objective (RTO) and Recovery Point Objective (RPO). This approach ensures the business remains 'always operational' while significantly reducing the 'man hours needed' by offloading physical infrastructure management to the cloud provider.
