When Elastic changed the licensing model of Elasticsearch, it sent shockwaves through the open source ecosystem. For AWS, it wasn’t just about a technology shift—it was a call to action. In a recent KubeStruck interview, David Nalley, Director of Open Source Strategy and Marketing at Amazon Web Services (AWS). shared the story behind OpenSearch, the open source search engine that AWS launched in response.

“Elasticsearch was foundational to a lot of workloads,” Nalley explained. “When the license changed, we felt an obligation to preserve that open source access, not just for our customers, but for the broader community.”

AWS responded by hard forking Elasticsearch and naming the new project OpenSearch. In the early days, the bulk of contributors came from AWS itself, but the long-term vision was clear: create an independent, community-driven project.

That vision has now come to fruition. OpenSearch has officially moved to the Linux Foundation, gaining independent governance under the OpenSearch Foundation. This move is more than symbolic—it ensures the project’s transparency, community input, and long-term stability.

Community engagement is core to the project’s success. Nalley emphasized that open source projects thrive only when there’s a “critical mass” of contributors invested in its growth. That growth is visible today, with OpenSearchCon—its flagship event—taking place soon in Amsterdam, organized by the Linux Foundation.
