How Red Hat describes OpenShift.

Recently, several of my friends recommended I look into OpenShift.  Here is how Red Hat describes OpenShift.

What is OpenShift: Red Hat, know by developers for its linuxstorage and cloud offerings and support for JAVAPHPPYTHON, and RUBY positions OpenShift as a Platform as a Service (PAAS) offering.  That is, OpenShift is a platform in the cloud where application developers can build, test, deploy, and run their applications.  To do so, OpenShift provides infrastructure, middleware, and management tools.

Usage: using OpenShift involves these steps. 1. Create an “Application” in OpenShift.  This can be done with the command-line or via an IDE.  2. Code the application with your favorite text editor or IDE.  Finally, 3. push the application code to OpenShift, with the command-line or from your IDE.

Supported languages: OpenShift supports Node.js, Ruby, Python, PHP, Perl, and Java. You can also any language with a “cartridge functionality” feature, and integrations have been developed for languages such as Clojure and Cobol.  Supported frameworks include Spring, Rails, and Play.

Elastic scaling: OpenShift provides automatic and manual scaling and clustering.

Selling points: Red Hat stresses leadership, stability, responsiveness, performance, security, and survivability.  Specifically, Red Hat emphasizes multi-tenancy, fine-grained security, and control over compute and storage resources. If desired, SELinux allows OpenShift to “firewall” one user’s application from another.  Red Hat believes that their “multi-tenant in the OS” approach vs. a “multi-tenant hypervisor” approach can scale resources more quickly
