Today, open source dominates IT and communications infrastructure from the cloud to corporate data centers and the emerging edge. But open source with its rapid pace of development, frequent releases, and prolific patch set defies traditional practices and conditions for building mission- and business-critical software: stability, auditability and standards-compliance.
