Now that the services used by an enterprise and provided to its customers may be hosted on servers in the public cloud or on-premises, maybe "hybrid cloud" isn't an architecture any more. While that may the case, that's not stopping some in the digital transformation business from proclaiming it a way of work unto itself.
Traditionally, a hybrid cloud runs simultaneously on a public and private cloud. Historically, that's been done with three models: Hybrid-cloud management software such as HPE Helion[3]; vendor-native hybrid cloud platforms, such as Microsoft with Azure[4] and Azure Stack[5]; and Platforms-as-a-Service (PaaS) clouds, including Cloud Foundry[6], which can bridge over Infrastructure-as-a-Service (IaaS) clouds.

In this next generation of Red Hat's Kubernetes platform, Red Hat explicitly stated OpenShift 4 is designed to deliver a cloud-like experience across the hybrid cloud by driving automated updates across Kubernetes deployments everywhere. Or, as Red Hat CEO Jim Whitehurst summed it
