2. Agenda
Platform As A Service
What’s about
OCP Components
Nodes, Masters and more
Openshift Features
Building and operating apps
Demo
Overview, Build, Blue Green
6. Platform As A Service
“A platform allowing customers to
develop, run, and manage applications
without the complexity of building and
maintaining the infrastructure typically
associated with developing and
launching an app”
7. How applications can run on a PAAS ?
● VMs (a bit on the edge…)
● Containers
● Code (functions)
Or a mix of that...
8. Cloud & PAAS
● Good match
● Overlaps
● PAAS for multicloud
13. So what is Openshift giving me?
● Web Gui, CLI, api
○ Create and manage applications
● Predefined template
○ Languages and MW
● Lots of goodies
○ Networking, builds, log aggregation, monitoring, security...

41. Developers write code using
existing development tools
such as Maven, NPM, Bower,
PIP, Dockerfile and Git and
then access the OpenShift
Web, CLI or IDE to create an
app from the code
DEPLOY SOURCE CODE WITH

42. S2I combines source code
with a builder image
(language and application
runtimes) and stores the
resulting application image
in the image registry

to build the app binaries (e.g.
