Think it’s likely
competitors will compete
in industries other than
their own over the next
three years
Half of US CEOs believe a significant
competitor is emerging or could
emerge from technology sector
versus 32% of CEOs globally.

9. OpenShift is Red Hat’s Container Application Platform
● Built for both traditional and cloud-
native applications.
● An integrated hybrid cloud application
platform for application development
and deployment
● Develop, build, and manage container
based applications
● Easily turn source code into running
applications with source-to-image
capabilities

26. OpenShift runs on your choice of infrastructure

27. Nodes are instances of RHEL where apps will run

28. App services run in docker containers on each node

29. Registry
Pods run one or more docker containers as a unit

30. Masters leverage kubernetes to orchestrate nodes / apps

31. Master provides authenticated API for users & clients

32. Master uses etcd key-value data store for persistence

33. Master provides scheduler for pod placement on nodes

34. Pod placement is determined based on defined policy

35. Services allow related pods to connect to each other

36. Management/Replication controller manages the pod lifecycle

37. What if a pod goes down?

38. OpenShift automatically recovers and deploys a new Pod

39. Pods can attach to shared storage for stateful services

40. Routing layer routes external app requests to pods

41. Developers access openShift via web, CLI or IDE

42. OpenShift
Source-2-Image

43. Code

Build
Can configure different
deployment strategies
like A/B, Rolling upgrade,
Automated base updates,
and more.
Can configure triggers for
automated deployments,
builds, and more.
Source 2 Image Walk Through

44. Developers can leverage existing
development tools and then access
the OpenShift Web, CLI or IDE
interfaces to create new application
services and push source code via
GIT. OpenShift can also accept
binary deployments or be fully
integrated with a customer’s existing
CI/CD environment.
Code
Source 2 Image Walk Through Can configure triggers for
automated deployments,
builds, and more.

45. OpenShift automates the Docker
image build process with Source-to-
Image (S2I). S2I combines source
code with a corresponding Builder
image from the integrated Docker
registry. Builds can also be triggered
manually or automatically by setting
a Git webhook.

Source 2 Image Walk Through Can configure triggers for
automated deployments,
builds, and more.

46. Deploy
OpenShift automates the deployment
of application containers across
multiple Node hosts via the
Kubernetes scheduler. Users can
automatically trigger deployments on
application changes and do rollbacks,
configure A/B deployments & other
custom deployment types.
