How Does Hot Standby Work?
When any running primary system fails or for any reason, it is not available then a backup system comes into the picture to run the system without any noticeable interruption to the users or end client. Now after that, the secondary system becomes the new primary system for the user or client.
- For example, when the primary CPU fails then the standby CPU will automatically become the primary CPU and take over the system in a short span of time.
- The two CPUs are connected with each other through a communication medium like Ethernet.
What is Hot Standby Mode?
In high-availability systems, Hot Standby Mode is a type of redundancy and failover strategy used to ensure continuous operation and minimize downtime in the event of a failure. The term “Hot Standby” refers to a secondary system that is kept ready or on standby and can take over the primary system’s operations in the event of a failure.
