Hot Site

A fully equipped alternate facility with current systems and data that can take over operations almost immediately.

Definition

Hot sites have hardware, software, network connectivity and near-real-time data replication in place, supporting RTOs of minutes to hours. They are the most expensive site type. Cloud regions with active standby environments serve as modern hot sites.

Example

A bank failing over to a secondary data center with synchronously replicated databases within an hour.

Exam tip

Hot = fastest recovery and highest cost; choose it for very short RTOs.
