ActivePassiveArchitekturen

ActivePassive Architekturen, often referred to as Active-Passive or Active/Passive architectures, represent a high-availability system design. In this setup, there are at least two components, one designated as active and the other as passive. The active component handles all incoming requests and performs the primary operations. The passive component, in contrast, remains in a standby state, ready to take over if the active component fails. This takeover is typically initiated automatically or manually. The passive component may be a mirror of the active one, holding identical data and configurations, or it might require some synchronization process upon activation. The primary goal of an Active-Passive architecture is to minimize downtime and ensure continuous service availability. When the active component experiences an outage, the passive component is quickly brought online to assume its role. This failover process can be seamless for end-users or may involve a brief interruption depending on the specific implementation. Common applications include critical databases, web servers, and network devices where uninterrupted operation is paramount. The trade-off for this increased reliability is often increased cost due to the need for redundant hardware and potentially complex failover management software.
