OpenShift

OpenShift Profile and History

OpenShift by Red Hat is built on open-source technologies (we are one of the world's leading open source companies, after all). A decade of enhancements in these technologies contributed by the open source community has resulted in a set of very robust technology components that provide the inner-workings of the OpenShift PaaS. OpenShift is built on a foundation of Red Hat Enterprise Linux (RHEL). Beyond being a leading and well respected Linux distro, RHEL provides some key capabilities that allow OpenShift to be stable, responsive, performant and secure. OpenShift leverages the multitenancy and security models within RHEL to provide fine-grained and trusted control over the compute and storage resources available to any single OpenShift application. SELinux allows OpenShift to "firewall" one user's application from another in order to insure security and survivability. Taking a "multi-tenant in the OS" approach vs. a "multi-tenant hypervisor" approach allows OpenShift to scale resources much more quickly so that your application will never lack the horsepower that it needs. Add on top of RHEL, a full selection of open source Languages, Frameworks, and Middleware combined with a "Cartridge" approach that allows users to very easily select the components that their applications need whether it is a NoSQL datastore or a Business Intelligence analytics engine.
