Active-Active Architecture
Active-Active Architecture is a high-availability design pattern where multiple instances of a system (e.g., servers, data centers, or clusters) operate simultaneously to handle user requests. It distributes workloads across all active nodes, ensuring redundancy and load balancing to maximize uptime and performance. This approach contrasts with Active-Passive setups where standby nodes only activate during failures.
Developers should implement Active-Active Architecture for mission-critical applications requiring minimal downtime, such as e-commerce platforms, financial services, or global web services, to ensure continuous availability during peak loads or regional outages. It is essential for scaling horizontally to handle high traffic volumes and improving disaster recovery by eliminating single points of failure.
