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.
- Primary (Active) Server: Under typical operational conditions, this server is the primary (active) server for production traffic. It is the primary point of contact for users of the service or application.
- Standby (Passive) Server(s): These servers are in standby mode, or effectively on standby, until they are required to take over operations from the primary server. They duplicate the primary server’s configuration and data to provide a smooth transition in the event of failure.
- Heartbeat Mechanism: A heartbeat mechanism is used to constantly check the health and availability of an active server. This mechanism detects symptoms of failure, such as unresponsiveness or system problems.
- Data Replication: Data replication procedures keep the data on the standby server(s) in sync with the data on the active server. This synchronization reduces the likelihood of data loss during failover and guarantees that the standby system can easily take over operations.
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.
