observability technical

"enterprise search, observability and analytics"

Observability is a company’s ability to see and understand what its software systems are doing by collecting and analyzing signals like logs, metrics and traces. For investors it matters because strong observability reduces the risk of downtime, hidden bugs or security issues, supports faster fixes and efficient scaling, and therefore can protect revenue, lower costs and signal disciplined operations — like having clear gauges and alarms on a complex machine.

vector database technical

"search, analytics, observability, and vector database software"

A vector database is a specialized system that stores and organizes data represented as lists of numbers, called vectors, which capture the important features of information such as images, text, or audio. It allows quick and accurate matching or searching for similar items based on their characteristics, much like finding similar songs or images in a vast library. For investors, this technology enables smarter data analysis and decision-making by efficiently handling complex, high-dimensional information.

Expanded commitments from Intel and more strengthen vendor neutral platform stability as global downloads grow 140% YoY and contributor participation surges

• The OpenSearch Software Foundation announced three new General Members – Adelean, Intel, and Sidecar – along with two new certified Long Term Support (LTS) providers, Seacom and Sidecar.
• In addition to Foundation growth, OpenSearch project contributors increased 31% year-over-year.
• The expanding ecosystem aligns with enterprise demands for vendor neutral, open source infrastructure, backed by new research showing that 71% of organizations consider independent data infrastructure deployment a strategic priority.

SAN JOSE, Calif., Sept. 22, 2026 /PRNewswire/ -- OpenSearchCon North America -- The OpenSearch Software Foundation, the neutral home for the OpenSearch Project, today announced increased member investment, certified vendor support commitments, and continued global adoption. The Foundation welcomed new General Members Adelean, Intel, and Sidecar, alongside new certified Long Term Support (LTS) providers Seacom and Sidecar.

"Proprietary software restricts flexibility and increases costs, especially with today's accelerating data demands," said Bianca Lewis, executive director of the OpenSearch Software Foundation. "Open source is the future of enterprise infrastructure, our members' commitment gives organizations the stability and confidence to run their most critical workloads in the open."

Expanding Enterprise Stability with New Members and Certified LTS Vendors
As new General Members of the OpenSearch Software Foundation, Adelean, Intel, and Sidecar will engage with working groups, contribute to technical initiatives, and help guide the strategic direction of the Foundation. Intel's membership builds on its existing open source technical contributions to OpenSearch, which help optimize performance through hardware-level acceleration.

Additionally, Seacom and Sidecar have formally joined the vendor directory as certified LTS providers. Through the Foundation's established LTS program, certified vendors deliver production-ready software stability, extended maintenance windows and predictable upgrade paths.

Recent research from OpenSearch Software Foundation and Linux Foundation Research underscores this momentum as 71% of organizations agree that deploying data infrastructure independently of a specific vendor is a strategic priority. Membership and certified support from these leading organizations strengthen OpenSearch's vendor neutral platform for enterprise search, observability and analytics via a growing ecosystem that delivers predictable, sustainable open source innovation.

Sustained Global Acceleration
The Foundation and OpenSearch project continue to grow in parallel. Over the past year, global community participation accelerated, including a 31% overall increase in contributors. Regionally, contributors increased 43% in Latin America, 33% in Japan, 16% in India and 10% in Europe. Total project downloads reached more than 2.4 billion – an increase of 140% year-over-year – reflecting growing trust in open platforms that future-proof enterprise search, observability, and analytics, and prevent vendor lock-in.

The OpenSearch Software Foundation community is gathering at OpenSearchCon North America in San Jose, California from Sept. 22-24. Register to attend here.
