What is Active-Passive Architecture?
Active-passive architecture, or a standby or failover system, involves a primary active system and a secondary passive system that remains inactive until the primary system fails. The primary system handles all incoming requests and operations while the passive system remains on standby, ready to take over if the primary system encounters a failure or becomes unavailable.
- In the event of a failure, the passive system is activated to assume the workload and responsibilities of the primary system, ensuring continuity of service and minimizing downtime.
- This architecture prioritizes redundancy and reliability, making it suitable for applications where uninterrupted service is critical, such as disaster recovery systems or mission-critical infrastructure.
Active Active vs. Active Passive Architecture
In system design, the debate between Active-Active and Active-Passive configurations sparks intense discussion. Active-Active employs parallel processing, allowing simultaneous use of multiple resources for enhanced performance and resilience. Conversely, Active-Passive relies on a standby system that activates only when the primary system fails, emphasizing redundancy over continuous utilization.
