What is Active-Passive Architecture?

Active-passive architecture, also known as standby or failover architecture, is a high availability configuration in which numerous identical systems are deployed, but only one is actively serving production traffic at a given time. The passive system(s) remain inactive until needed, acting as backups in case the active system fails. The major purpose of active-passive architecture is to assure service continuity by swiftly switching to the standby system if the active system fails.

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.

Components and Characteristics of Active-Passive Architecture

Active-passive architecture features two sets of components: active and passive. The active components handle normal operations, while the passive ones remain on standby, ready to take over in case of failure....

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....

Load Balancing and Traffic Distribution Strategies in Active-Active Architecture

Round-robin: Requests are delivered in a circular pattern across active servers to ensure an equitable distribution of traffic. Least Connections: Requests are directed to the server with the fewest active connections, which helps to equally share the demand. Weighted Round-robin: Different weights can be allocated to servers based on their ability to handle traffic, resulting in more effective resource use....
