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

CONTAINERS v VMs
Traditional Virtualization What Defjnes Virtualization?
- Virtual hardware boundaries
- Hypervisor
- One OS instance per VM
- IaaS paradigm
Hardware Host OS Hypervisor Guest OS Guest OS bins/libs bins/libs App A App B
And Often:
- Can Run any OS
- Full software Stack
- Very isolated guests

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

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

Walkthrough
SLIDE 13
OpenShift runs on your choice of infrastructure
SLIDE 14
Nodes are instances of RHEL where apps will run
SLIDE 15
App services run in docker containers on each node
SLIDE 16
Registry
Pods run one or more docker containers as a unit
SLIDE 17
Masters leverage kubernetes to orchestrate nodes / apps
SLIDE 18
Master provides authenticated API for users & clients
SLIDE 19
Master uses etcd key-value data store for persistence
SLIDE 20
Master provides scheduler for pod placement on nodes
SLIDE 21
Pod placement is determined based on defined policy
SLIDE 22
Services allow related pods to connect to each other
SLIDE 23
Management/Replication controller manages the pod lifecycle
SLIDE 24
What if a pod goes down?
SLIDE 25
OpenShift automatically recovers and deploys a new Pod
SLIDE 26
Pods can attach to shared storage for stateful services
SLIDE 27
Routing layer routes external app requests to pods
SLIDE 28
Developers access openShift via web, CLI or IDE
