R E P O R T Open Source Software Usage, Market Trends, Executive Summary The 2025 State of Open Source Report provides critical insights into the current trends, challenges, and priorities shaping open source software (OSS) adoptionamong organizations worldwide. The findings highlight both opportunities and obstacles for companies of all sizes leveraging OSS across industries and regions. 1.OSS Adoption Surges Despite Challenges •96% of organizations reported increasing or maintaining their use of OSS, with 26% significantly increasing utilization last year.•The top reason cited for OSS adoption continues to be cost reduction, with “no license cost/overall cost reduction” emerging as the primary driver 2.Persistent Usage of End-of-Life (EOL) Software •26% of organizations are still using EOL CentOS, including 40% of large enterprises. Alarmingly, 25% of these enterprises have yet to decide on amigration plan. 3.Low Confidence in Big Data Management •Nearly half (47%) of organizations handling Big Data reported low confidence in managing those platforms.•The complexity and rapid evolution of open source data technologies is a factor, with more than 75% naming lack of personnel and skill gaps as a top barrier. 4.Challenges in Security and Compliance •Across industries, organizations are struggling with security and compliance management. Key pain points include keeping up with updates and patches, Presented in Collaboration With Contents 4........About the Survey6........Open Source Usage, Investment, and Support Challenges13......Open Source Linux Distributions14A Snapshot of CentOS Usage Post-EOL16......Open Source Infrastructure Software18......Cloud-Native Open Source Technologies20......Open Source Frameworks About the Survey The 2025 State of Open Source Report is based on an anonymous survey conducted between September 17 and December 20, 2024. The survey received 433 We started by asking respondents some initial demographic and firmographic questions about location, industry, organization size, and title. Region Industry Just like last year, the largest percentage of this year’s respondents — more thana quarter — work in the technology sector. Education or research and banking, This year for the first time, we received the greatest response from Europe,comprising almost a third of the survey population (31.64%). North Americacame in second (28.18%), followed by Asia (13.63%) and Africa (10.85%). Job Title Organization Size Nearly half (49.89%) of our respondents are hands-on practitioners working assystems administrators, developers, engineers, and architects. Roughly a fifth(20.55%) are in manager, team lead, and director positions, and a little over5% are in executive leadership roles. The remainder identify as consultants, Organizations of all sizes work with open source, and the following graphshows the breakdown by size for our survey takers. Interestingly, more thanhalf (roughly 54%) work for either the smallest companies and startups (20employees or fewer) or the largest enterprises (more than 5,000 employees). Unsurprisingly, there is a correlation between company size and numberof servers in IT infrastructure; more than 50% of respondents from thelargest companies deploy more than 1,000 servers (and 28% deploy 10,000+), Looking at a cross-section of region and size, a slightly higher percentage ofrespondents working for the largest enterprises are located in North America(37.78%) compared to Europe (25.56%) while those working for smallercompanies (headcount under 100) are predominantly based in Open Source Usage, Investment, Next, we asked if organizations are using more or less open source thisyear, what kinds of technologies they are investing in, and what obstacles Open Source Software Usage: Did It Grow,Stay the Same, or Decline? 96% of organizations either increased or maintained their use of opensource software in the past year — and a quarter (25.71%) reported a 96% of organizations increased ormaintained their OSS usage last year.Slightly more than a third (34%) of 68% of the largest enterprises increased or significantly increased their OSS use last year. For the other size brackets, we saw greater percentages than in previousyears saying their OSS usage stayed the same. Adopting new technologies often requires additional personnel, which may not be possible in this economic climate,particularly for smaller companies and early-stage startups. As we have seen year after year, finding and retaining individuals with the necessary skills and experience By industry, technology had the highest percentage (37%) of respondents noting significant increase of OSS. Why Organizations Are Choosing Open Source Software What is motivating organizations to adopt open source over proprietary software?In previous years, no license cost/cost reduction was a factor, but not the primary one —but that has definitively shifted. For the second year in a row, cost savings
