Agenda
• Where do OpenShift and Kubernetes come from & what makes them special?
• What is happening in the community?
• A look into the crystal ball to see what the future might bring

3. OpenShift Evolution: Past, Present, Future Folie 3
Where do OpenShift and K8s come from & what makes them special?
• 2011 OpenShift 1.0
• 2013 Docker 1.0
• 2014 Kubernetes 1.0
• 2015 OpenShift 3.0
• 2019 OpenShift 4.0 Operator Framework, Multi-cluster Manager, Knative, Service Mesh, …

4. OpenShift Evolution: Past, Present, Future Folie 4
Where do OpenShift and K8s come from & what makes them special?
• OpenShift 3.3  CI/CD based on Jenkins, A/B Deployment
• OpenShift 3.4  Storage Quota, Job API, Dynamic Storage for public clouds
• OpenShift 3.7-  Service Broker, Network Policies

• OpenShift 4.0  Operator Framework, Multi-cluster Manager, Knative, Service Mesh, …

5. OpenShift Evolution: Past, Present, Future Folie 5
Difference OpenShift vs Kubernetes
OpenShift is based on Kubernetes and offers services and enhanced security out of the box

What makes K8s special?
There are very large ecosystems of frameworks and applications that are using K8s
• Helm  “Package manager for Kubernetes”
• Spinnaker  “Cloud native Continuous Delivery”
• Istio  Advanced routing between container
• Knative  Deploy and manage modern serverless workload
• …
In general: For almost every application you can find an example how to run it on K8s

10. OpenShift Evolution: Past, Present, Future Folie 10
What makes K8s special?
It is used and therefore properly tested by a lot of companies
It is starting to become a catalyst to standardize frameworks and tools
• Container Runtime Interface (CRI)
• Container Networking Interface (CNI)
• Container Storage Interface (CSI)
• …
Deployment and running applications on K8s is relatively easy

11. OpenShift Evolution: Past, Present, Future Folie 11
What makes K8s special?
The installation of Kubernetes is another story…

12. OpenShift Evolution: Past, Present, Future Folie 12
What is happening in the community?
• Focus on management of multi/hybrid cloud
• Standardize build flow in Kubernetes with Tekton
• Standardize Serverless execution in Kubernetes with Knative
• Istio and Service meshes

13. OpenShift Evolution: Past, Present, Future Folie 13
Look in the crystal ball to see what the future might bring
With respect to the clusters:
• Simpler and more robust installation und updates of Kubernetes and OpenShift
• Run more than one cluster and possibly with more then one cloud provider
• Simpler scaling of nodes in cluster to reduce costs
• Also starting of pod without nodes i.e. AWS Fargate
• Integration with GPU to support ML and AI
• Run VM’s in an K8s/OpenShift cluster

14. OpenShift Evolution: Past, Present, Future Folie 14
Look in the crystal ball to see what the future might bring
With respect to applications of frameworks
• Operators to install, update and delete applications
• Serverless (not necessary FaaS) application to reduce costs
• Stronger integration of Istio or Services Meshes to have flexible routing without changes in
source code

15. OpenShift Evolution: Past, Present, Future Folie 15
Look in the crystal ball to see what the future might bring
With respect to the developer
• Tekton to build application in Kubernetes
• Run developer workspaces in the cluster with Eclipse Che
• Alternatives to Docker as runtime and to build container like podman

16. OpenShift Evolution: Past, Present, Future Folie 16
Look in the crystal ball to see what the future might bring
With respect to Operating Systems
• Kubernetes/OpenShift run native Windows pod/container

17. Any questions?
