Failover Process and Recovery Mechanisms in Active-Passive Architecture
- Failure Detection: The heartbeat system detects when the active server fails or becomes unavailable. This might be a result of device failure, software flaws, or network problems.
- Automatic Failover Trigger: When a failure is detected, the failover procedure is initiated automatically. This procedure comprises starting the backup server to take over the functions of the failing primary server.
- Traffic Redirection: Traffic is diverted from the failing primary server to the backup server to ensure that users continue to receive service.
- Standby Server Activation: The standby server takes over as the new active server, taking all of the tasks formerly held by the primary server.
- Recovery methods: After activating the standby server, recovery methods guarantee that data stays consistent and the service or application resumes to normal operation without any noticeable impact on users.
Active Passive & Active Active Architecture for High Availability System
Active-Passive and Active-Active architectures stand out as two important strategies for achieving high availability. These architectures offer distinct approaches to distributing workloads, managing resources, and mitigating downtime, each tailored to address specific operational requirements and scalability demands.
