According to G2 reviewers, CentOS's pricing — free — makes it best suited for organizations with in-house Linux expertise that want RHEL compatibility without subscription costs. Mid-market companies in IT services, financial services, education, and telecommunications appear frequently among G2 reviewers, using CentOS for web servers, databases, ERP systems, and CI/CD pipelines. Enterprise reviewers in higher education and IT use CentOS to train staff on RHEL-equivalent environments. Small businesses running LAMP stacks and web applications also feature prominently. G2 data on CentOS's pricing suggests it is least suited for organizations requiring vendor-backed support SLAs or teams without dedicated Linux administration capability.
