This document discusses OpenShift, a platform as a service (PaaS) that allows users to deploy and scale applications in a cloud hosting environment. It provides an overview of OpenShift's architecture, including gears (container servers), cartridges (application components), and tools for managing applications. The presentation aims to introduce OpenShift's core concepts and demo its capabilities for hosting and scaling applications.

- 5. Openshift Massimiliano Dessi 5 Software as a Service (Saas) ● Sign in and use the service Gmail, Dropbox, Evernote, FB, Twitter
- 6. Openshift Massimiliano Dessi 6 Platform as a Service (Paas) ● Between Iaas and Saas the platform spins up the dev env with all the “server” pieces you need to run your application
- 7. Openshift Massimiliano Dessi 7 Openshift PaaS ● Three version OpenShift Origin (https://openshift.github.io/) OpenShift Online (https://www.openshift.com/) OpenShift Enterprise

- 9. Openshift Massimiliano Dessi 9 Basics ● Application Your typical web application that will run on OpenShift. ● Open‐Shift is focused on hosting web applications. With this in mind, for security reasons, the only ports exposed to incoming traffic are HTTP (80), HTTPS (443),SSH (22), WebSocket HTTP (8000) and HTTPS (8443).
- 10. Openshift Massimiliano Dessi 10 Basics ● Gear A gear is a server container with a set of resources that allows users to run their applications. Your gears run on OpenShift. ● There are three gear types on OpenShift Online: ● small, medium, and large. Each size provides 1 GB of disk space by default. ● The large gear has 2 GB of RAM, the medium gear has 1GB of RAM, and the small gear has 512 MB of RAM
- 11. Openshift Massimiliano Dessi 11 Basics ● Cartridge Cartridges are the plug-ins that that can be used to create and run an application (framework or components). ● One or more cartridges run on each gear, and the same cartridge can run on many gears for clustering or scaling. There are two kinds of cartridges: Standalone Embedded
- 12. Openshift Massimiliano Dessi 12 Basics ● Scalable application Application scaling enables your application to react to changes in traffic and automatically allocate the necessary resources to handle your increased demand. ● The OpenShift infrastructure monitors web traffic and automatically brings up new gears with the appropriate web cartridge to handle more requests. When traffic decreases, the platform removes the extra resources.
- 13. Openshift Massimiliano Dessi 13 Basics ● Client tools, Web Console /Eclipse plug-ins You can interact with the OpenShift platform via RHC client command-line tools, installed on your local machine, the OpenShift Web Console, or a plug-in in Eclipse to interact with your application in the OpenShift cloud. ● The rest of your work with your application will happen through Git and SSH.
