The Warm Standby approach in disaster recovery is designed to achieve lower Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO) values. This approach involves having a scaled-down version of a fully functional environment running at all times in the cloud. In the event of a disaster, the system can quickly switch over to the warm standby environment, which is already running and up-to-date, thus ensuring a quick and complete restoration of applications.

Here’s how the Warm Standby approach works:

• Prepared Environment: A duplicate of the production environment is running in the cloud, but at a reduced capacity.
• Quick Activation: In case of a disaster, this environment can be quickly scaled up to handle the full production load.
• Data Synchronization: Regular data synchronization ensures that the standby environment is always up-to-date, which contributes to a low RPO.
• Reduced Downtime: Because the standby system is always running, the time to switch over is minimal, leading to a low RTO.
• Cost-Efficiency: While more expensive than a cold standby, it is more cost-effective than a hot standby, balancing cost with readiness.
