Active-Active
Active-Active is a high-availability architecture where multiple systems or components operate simultaneously to handle workloads, ensuring redundancy and load balancing. It is commonly used in distributed systems, databases, and network configurations to provide continuous service availability and improved performance. This setup allows for seamless failover and scalability by distributing traffic across all active nodes.
Developers should learn Active-Active for building resilient applications that require minimal downtime and high throughput, such as e-commerce platforms, financial services, or real-time data processing systems. It is essential in scenarios where single points of failure are unacceptable, enabling automatic traffic redirection during failures and efficient resource utilization under varying loads.
