What does "Failover" imply in the IPO system?

The concept of "Failover" in the context of the IPO system refers specifically to the process of automatically switching to a backup or redundant system when the primary system encounters a failure. This mechanism is crucial for ensuring high availability and reliability within a network infrastructure.

In a failover scenario, if the primary system goes down due to hardware failure, software issues, or any unforeseen circumstances, the system can seamlessly transition to a backup system without requiring manual intervention. This automatic process helps maintain continuity of service, reducing downtime and minimizing disruption for users and businesses.

The other options do not align with the standard definition of failover. For instance, manual switching indicates a need for human intervention, which contrasts with the automatic nature of failover. Data deletion is unrelated to failover and focuses more on performance optimization rather than system reliability. Constant online monitoring may contribute to identifying issues ahead of time but does not denote a failover process. Thus, the automatic aspect of switching systems upon failure is the defining characteristic of failover in the IPO system.
