Technical Consistency in an OpenShift Context

Operational consistency requires Technical consistency RHEL and OpenShift Consistency 10 Fewer variables Risk offloaded to the platform Better visibility Faster remediation cycles OPERATIONS SECURITY Commoditization of infrastructure Better scale for talent Easier integrations DEVELOPMENT Faster onboarding Less guesswork Less bikeshedding Platforms and Consistency
