What are the best practices for implementing active-active architecture?

Active-active architecture involves multiple active nodes that can handle requests simultaneously. Best practices include ensuring data consistency, implementing load balancing, and using health checks to monitor node status.

How do I ensure data consistency across active nodes?

To ensure data consistency, consider using distributed databases with strong consistency models, or implement conflict resolution strategies to handle discrepancies.

What load balancing techniques are recommended?

Recommended load balancing techniques include round-robin, least connections, and IP hash. Choose based on your traffic patterns and application needs.

Can you explain the importance of health checks?

Health checks are crucial for identifying failed nodes and ensuring traffic is only directed to healthy ones, maintaining system reliability.

What are some common challenges with active-active architecture?

Common challenges include managing data replication, handling network partitions, and ensuring low latency across nodes.
