Overview
- AWS launched the next-generation OpenSearch Serverless on Thursday, May 28, 2026, with a near-total rebuild that decouples storage from compute to meet bursty machine-to-machine traffic patterns.
- The service can scale to zero when idle and AWS says the new design and a proprietary compressed storage layer can lower costs by up to 60 percent versus provisioned peak clusters.
- AWS reports autoscaling that is about 20 times faster than the prior version, cutting collection cold-starts from minutes to seconds and making real-time retrieval practical for agents.
- OpenSearch Agent Skills and native integrations with tools like Vercel, Kiro, Claude Code and Cursor let agents access and be monitored by OpenSearch without custom plumbing.
- AWS published a product roadmap that adds log analytics in June, a timeseries collection later at its New York summit, and plans for long-term agent memory, evaluation/governance and a search reasoning model in 2026.
