Key Concepts

Redundancy

Redundancy refers to the inclusion of extra components or systems that are not strictly necessary for functioning under normal conditions, but can take over operation if the primary component fails. In system design, redundancy is used to ensure continuous operation and enhance reliability by providing backup resources that seamlessly become active during a fault condition.

Failover Mechanism

The failover mechanism is the process by which a system automatically switches to a backup component when a primary component fails. This is an essential part of designing resilient systems, as it minimizes downtime and ensures that the system maintains functionality even in the face of hardware or software failures.

Primary and Secondary System Design

In systems that use a primary and secondary configuration, the primary component is the main operational unit while the secondary component is kept in reserve to provide support if the primary fails. This design strategy is used to allocate resources in a way that maintains service continuity, with the secondary system being structured to take on the load or role of the primary system in a controlled manner.
