In this session, we'll share our experience managing over 1,000 OpenSearch clusters in a private cloud, focusing on technologies used for stable operations and cost reduction. The LINE Cloud team provides OpenSearch as a backend for various LINE services, aiming for automated operations with minimal user intervention. We'll detail our service architecture utilizing Kubernetes and OpenStack, focusing on stability, scalability, and automation.
Additionally, we intend to share our experience collaborating with the storage team to design lightweight storage solutions for OpenSearch. This solution and our architecture enable high performance while reducing maintenance costs. In a recent migration case, we achieved a 22% reduction in infrastructure costs for OpenSearch 'hot' nodes. Also, we'd like to share some of the issues we encountered under high load situations to share our experiences on the private cloud. This session will offer practical insights for engineers interested in operating OpenSearch in their own environment.
