OpenSearchCon India 2026

This session explores building and maintaining highly available OpenSearch clusters with robust disaster recovery strategies. We'll examine critical components of resilient OpenSearch infrastructure, focusing on multi-node cluster design across availability zones and effective backup solutions. The presentation covers essential aspects of shard allocation, replica configuration, and cross-cluster replication for continuous operation during failures. Learn practical approaches to automated failover, snapshot management, and monitoring strategies for optimal cluster health. Through real-world examples and lessons learned from large-scale implementations, we'll discuss common pitfalls and best practices for both cloud and on-premises deployments. This talk is designed for OpenSearch administrators, DevOps engineers, and architects managing mission-critical search infrastructure.
