STARTS WITH CONTAINERS Containers are just like the ISO shipping container that revolutionized the shipping industry Separation of concerns ● User cares about packing the inside – Shipper cares about moving the container – Standardized interface ● 5 OpenShift

CONTAINERS v VMs Traditional Virtualization What Defjnes Virtualization? V irtual hardware boundaries ● App A App B Hypervisor ● One OS instance per VM bins/libs bins/libs ● IaaS paradigm Guest OS Guest OS ● Hypervisor And Often: Host OS C an Run any OS ● Hardware Full software Stack ● Very isolated guests ● 7 OpenShift

CONTAINERS v VMs Containerization, aka OS Virtualization What Defjnes Containerization? Horizontal segmentation ● Container API ● App A App B Single OS instance ● bins/libs bins/libs Multi-tenancy ● Bare metal, virtual, cloud Container API ● Host OS And often: Hardware Near zero boot time ● Cannot run any OS ● 8 OpenShift

Open Container Initiative ● Announced on June 22, 2015 ● Industry leaders unite to create open standards and governance for container format and runtime ● Red Hat is a founding member of the Open Container Initiative and a leader in Linux and multiple container related open source projects ● Standardization is critical to foster innovation and will help drive adoption with customers and facilitate a rich container ecosystem

OpenShift and native .Net ● OpenShift will be providing a .NET runtime distributed and supported by Red Hat and Microsoft ● Will start with version 5 of the core framework ● Version parity goal of 60 days. * https://blog.openshift.com/open-source-power-microsoft-dotnet-openshift * = Coming Soon

OpenShift Commons An interactive community for all OpenShift PaaS Users, Customers, Contributors, Partners, Service Providers and Developers to share ideas, code, best practices, and experiences. More at http://commons.openshift.org/

OpenShift Product Deep Dive

Walkthrough

OpenShift runs on your choice of infrastructure

Nodes are instances of RHEL where apps will run

App services run in docker containers on each node

Pods run one or more docker containers as a unit Registry

Masters leverage kubernetes to orchestrate nodes / apps

Master provides authenticated API for users & clients

Master uses etcd key-value data store for persistence

Master provides scheduler for pod placement on nodes

Pod placement is determined based on defined policy

Services allow related pods to connect to each other

Management/Replication controller manages the pod lifecycle

What if a pod goes down?

OpenShift automatically recovers and deploys a new Pod

Pods can attach to shared storage for stateful services

Routing layer routes external app requests to pods

Developers access openShift via web, CLI or IDE
