The OpenSearch Software Foundation is pleased to announce that CERN has joined as an associate member. The intergovernmental organization operates the world’s largest particle accelerator and is responsible for landmark discoveries in particle physics, including the Higgs boson.
CERN has been running OpenSearch in production since 2016, making them one of the project’s earliest adopters. Today, they operate 130 OpenSearch clusters indexing over 1.3 petabytes of data, primarily for log analytics and search applications supporting high energy physics research portals. CERN is also exploring OpenSearch as a vector database and for AI-driven applications.
“CERN represents exactly the kind of organization we built this Foundation to serve. They’ve been running OpenSearch at an extraordinary scale for nearly a decade, supporting some of the most demanding research workloads in the world. Their deep expertise in observability, cluster monitoring, and Kubernetes operations will be a real asset to the community, and we expect their contributions to have a meaningful impact on how OpenSearch evolves in those areas. We’re thrilled to welcome them as an associate member and look forward to everything we’ll build together.” — Bianca Lewis, Executive Director, OpenSearch Software Foundation
As a Foundation member, CERN will contribute expertise in observability, cluster monitoring, and Kubernetes-based operations. Their team is actively working with the OpenSearch Kubernetes operator and plans to share knowledge gained from operating OpenSearch at significant scale within a global research environment.
“As members of the OpenSearch Software Foundation, we are aspiring to contribute further our knowledge in observability, monitoring, and operating OpenSearch clusters, and within the Kubernetes world where we are already testing our transition using the Kubernetes OpenSearch operator.” — Sokratis Papadopoulos, OpenSearch Service Lead, CERN
