Build Your Own PaaS, Just like Red Hat's OpenShift from LinuxCon 2013 New Orleans CloudOpen
The document introduces OpenShift, an open-source Platform as a Service (PaaS) developed by Red Hat, emphasizing its advantages for application deployment in the cloud, such as automatic scaling and security features. It contrasts different cloud service models—Infrastructure as a Service (IaaS), Software as a Service (SaaS), and PaaS—highlighting how PaaS provides a managed runtime environment. Additionally, it discusses the architecture, extensibility with cartridges, and the collaborative community surrounding OpenShift for further development and usage.
