● Containers, Microservices and DevOps● Openshift v3 overview
● DevOps● Management● Cloud infrastructure
● Commercial offering
Containers, Microservices and DevOps
Why should you care?
http://www.techrepublic.com/article/gartners-10-big-trends-that-will-change-how-it-operates/
Increase agility and enable DevOps
Containerize traditional applications
Move to microservices & hybrid cloud architectures
Why enterprise IT is looking at containers3 Common Conversations
What are Linux Containers?Software packaging concept that typically includes an application and all of its runtime dependencies
● Easy to deploy and portable across host systems
● Isolates applications on a host operating system
● In RHEL, this is done through:● Control Groups (cgroups)● Kernel namespaces● SELinux, sVirt, iptables● … Docker

public class HelloWorld {
public static void main(String[] args) { System.out.println ("Hello, World"); }}
#include<stdio.h>
main(){ printf("Hello World");}
var http = require('http');var server = http.createServer( function (request, response) { response.writeHead(200, {"Content-Type": "text/plain"}); response.end("Hello World\n");});server.listen(8000);
$_ = "hello world";$_ =~ s/^(\b\w)(\B\w+)\s(\D)(\D+)$/ \U$1\E$2 \U$3\E$4\!\n/;print $_;

Consistent Packaging Format
Docker provides a language agnostic packaging format and runtime API. Packaged dependencies ensure consistency and portability*
* The one thing not packaged is the Linux Kernel!
Images are layered
● Images are based on a parent
● The layers stack on top
● Filesystems are merged
● Each commit creates a layer
● Base image has no parent
● Images are stored in the Registry

Packaged dependencies = faster boot times + greater portability

var http = require('http');var server = http.createServer( function (request, response) { response.writeHead(200, {"Content-Type": "text/plain"}); response.end("Hello World\n");});server.listen(8000);

# of critical, important and moderate vulnerabilities identified and fixed by Red Hat in RHEL 7 since GA
Security is definied within containers
What's inside the container and where it comes from matters

Red Hat Container Certification
UNTRUSTED● Will what’s inside the containers
compromise your infrastructure?● How and when will apps and libraries
be updated?● Will it work from host to host?
RED HAT CERTIFIED ● Trusted source for the host and the
containers● Trusted content inside the container with
security fixes available as part of an enterprise lifecycle
● Portability across hosts
Standalone Docker is not enough
Enterprise needs container runtime and delivery platform
