1. Or: “Why does the RHEL guy care so much about OpenShift?” Platforms and Consistency Gunnar Hellekson VP, RHEL 1
2. MISSION 2 We are everywhere you want us to be. We serve the Red Hat portfolio and the larger Red Hat ecosystem. We are the source for safe and reliable Linux innovation that make your workloads successful. Mission Statement

Additional capabilities listed are from the Red Hat Application Services and Red Hat Data Services portfolios. ** Disaster recovery, volume and multicloud encryption, key management service, and support for multiple clusters and off-cluster workloads requires OpenShift Data Foundation Advanced Observability | Discovery | Policy | Compliance | Configuration | Workloads Image management | Security scanning | Geo-replication Mirroring | Image builds Declarative security | Container vulnerability management | Network segmentation | Threat detection and response RWO, RWX, Object | Efficiency | Performance | Security | Backup | DR Multicloud gateway Cluster data management
9. Technical Consistency in an OpenShift Context
10. 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
