OpenShift can refer to OpenShift Origin, RedHat OpenShift Online, Openshift Dedicated, OpenShift Container Platform or OpenShift.io.
OpenShift Origin is a computer software product from Red Hat for container-based software deployment and management. It is a supported distribution of Kubernetes using Docker containers since September 2013 and DevOps tools for accelerated application development.
OpenShift Origin, also known since August 2018 as OKD is the upstream community project used in OpenShift Online, OpenShift Dedicated, and OpenShift Container Platform. Built around a core of Docker container packaging and Kubernetes container cluster management, Origin is augmented by application lifecycle management functionality and DevOps tooling. Origin provides an open source application container platform. All source code for the Origin project is available under the Apache License (Version 2.0) on GitHub.
Online offered version 2 of the Origin project source code, which is also available under the Apache License Version 2.0. This version supported a variety of languages, frameworks, and databases via pre-built "cartridges" running under resource-quota "gears". Developers could add other language, database, or components via the OpenShift Cartridge application programming interface. This was deprecated in favour of OpenShift 3 and was withdrawn on 30 September 2017 for non-paying customers and 31 December 2017 for paying customers.
OpenShift Dedicated is Red Hat's managed private cluster offering, built around a core of application containers powered by Docker, with orchestration and management provided by Kubernetes, on a foundation of Red Hat Enterprise Linux. It is available on the Amazon Web Services (AWS) and Google Cloud Platform (GCP) since December 2016 marketplaces.
OpenShift Container Platform (formerly known as OpenShift Enterprise) is Red Hat's on-premises private platform as a service product, built around a core of application containers powered by Docker, with orchestration and management provided by Kubernetes, on a foundation of Red Hat Enterprise Linux.
Istio, released on July 31, 2018, is a microservices management program used in tandem with the Kubernetes platform. The software purports to provide "traffic management, service identity and security, policy enforcement and telemetry" services in order to streamline Kubernetes use under the various Fedora-based operating systems. Red Hat's Brian Redbeard Harring described Istio as "aiming to be a control plane, similar to the Kubernetes control plane, for configuring a series of proxy servers that get injected between application components".
