OpenShift is a Platform-as-a-Service that provides development environments on demand using containers. It automates application lifecycles including build, deploy, and retirement. OpenShift uses containers to package applications and dependencies in a portable way. Red Hat addresses concerns around adopting containers at scale through OpenShift, which provides security, scalability, integration, management and certification capabilities. OpenShift runs on a user's choice of infrastructure and orchestrates applications across nodes using Kubernetes.

2. What is OpenShift?
●OpenShift is a Platform-as-a-Service (PaaS)
●Provides development environments on demand (self service)
●Provides languages, frameworks, runtimes, and databases (polyglot)
●Automates application lifecycle management (build, deploy, retire)
●Enables collaboration between developers on projects and components
●Uses industry standards

3. Containers
● Software packaging concept
○ Application and its runtime dependencies
● Easy to deploy and portable across host systems
● Isolates applications on a host operating system
● Encourage microservices
● Immutable

11. Walkthrough

12. OpenShift runs on your choice of infrastructure

13. Nodes are instances of RHEL where apps will run

14. Applications run in docker containers on each node

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

16. Masters leverage kubernetes to orchestrate nodes / apps

17. Master provides authenticated API for users & clients

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

19. Master provides scheduler for pod placement on nodes

20. Pod placement is determined based on defined policy

21. Services allow related pods to connect to each other

22. Management/Replication controller manages the pod lifecycle

23. “Burn down”/replace affected deployments

24. OpenShift automatically recovers and deploys a new Pod

25. Pods can attach to shared storage for stateful services

26. Routing layer routes external app requests to pods

27. Developers access openShift via web, CLI or IDE

30. “We know this will take time and that it is not a simple endeavor. We are not
necessarily moving at the fastest pace because we really want to ensure The
Next Platform is capable of hosting more complex applications.”

31. How Amadeus talks about OpenShift
“To ensure consistency across a wide variety of platforms independent of the
underlying IaaS provider. A developer working on a laptop should be able to deploy
those applications on public clouds or the internal OpenShift cloud seamlessly,
relatively effortlessly, and consistently.”
