Keynote: OpenSearch on Kubernetes at Atlassian
summary
At Atlassian OpenSearch runs across 300+ clusters, ~2,000 nodes and ~20 billion documents; the team builds on the OpenSearch Kubernetes Operator to automate provisioning, upgrades and multi-cloud topology. Key additions: blue-green migration inside the operator to create new node pools and migrate shards reliably, Kubernetes startup probe to avoid yellow clusters during node recycling, ECDSA certificate rotation and automatic cert renewal, and Carpenter-driven dedicated hosts per OpenSearch node. Many changes are upstreamed to the community.
