Differences between Active-Active and Active-Passive Architecture
Below are the differences between the Active-Active and Active-Passive Architecture:
Aspect |
Active-Active Architecture |
Active-Passive Architecture |
---|---|---|
System Configuration |
Multiple identical resources are simultaneously active. |
Primary active system and secondary passive system on standby. |
Workload Distribution |
Workloads are distributed across all active resources. |
All workloads are handled by the primary system; passive system remains inactive until failover. |
Utilization |
Resources are continuously utilized, maximizing efficiency. |
Passive system remains idle until activated, leading to lower overall resource utilization. |
Fault Tolerance |
High fault tolerance as system can withstand individual node failures without service disruption. |
Relies on failover mechanism to switch to the passive system in case of primary system failure, leading to potential downtime during failover. |
Scalability |
Scales effectively with increasing workload by adding more active resources. |
Limited scalability as the passive system remains idle until failover, necessitating manual intervention or automated failover mechanisms. |
Complexity |
Generally more complex to configure and manage due to distributed nature. |
Relatively simpler configuration and management as it involves fewer active components. |
Use Cases |
Suitable for applications requiring high availability and scalability, such as cloud services and high-traffic websites. |
Ideal for mission-critical systems where minimizing downtime is paramount, such as disaster recovery systems and financial transactions. |
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.
