New OpenSearch Serverless architecture, actionable for cloud data engineering.
Summary
AWS launched the next generation of OpenSearch Serverless with a NextGen architecture that decouples compute (OCUs) from shared storage, enabling 20x faster provisioning, true scale-to-zero, and up to 60% lower cost than provisioned clusters. Positioned for agentic AI, it integrates with Cursor, Kiro, Vercel, Claude Code, and Codex, and introduces a per-account regional endpoint via AWS PrivateLink for unified collection access. Existing collections use the Classic architecture, while new ones default to NextGen.
