DECOMPOSITION

#redhat #rhsummit

It worked on my machine

INT, STG, QA, and prod MIGHT BEslightly different

Patching Prod may break myapplication

Admins must guess what patchesapply to my application

My application has a differentlifecycle than the OS

Tracking libraries is risky

Modern applications have TONS ofNIH code

WHAT I BUILD, RUNS

CONTENT MATTERS

#redhat #rhsummit

NOT ALL RAINBOWS...APPROACH

Re-architecting for services is expensive

Not all applications are appropriate (yet)

DevOps isn't just tools

Silos like holding grain

WHAT IS THE CDK?I T H E L P S YO U B U I L D C O N TA I N E R S

FROM THE WEBSITE

Red Hat Container Development Kit is a pre-builtcontainer development environment based onRed Hat Enterprise Linux to help you get starteddeveloping container-based applications quickly. Thecontainers you build can be easily deployed on anyRed Hat container host or platform, including:Red Hat Enterprise Linux, Red Hat Enterprise LinuxAtomic Host, and our platform-as-a-service solution,OpenShift Enterprise 3.

WHAT IS THE CDK?I T H E L P S YO U B U I L D C O N TA I N E R S

FOR REALS*

All the hard bits are setup already

Vagrant VM (hyper-v, vbox, kvm)DockerKubernetesOpenShift

You can use what you needThe technologies are setup mimickinga light production deployment HowTos, examples, and sample projectsavailableEclipse Integration

* /me dates myself

A BIT ABOUT THE BITS

DOCKER

A containerizing technology

Most popularGeared to server applicationsa number of others (e.g. flatpak, lxc,rkt)

Runs as a daemon on Linux

Implementations on Mac & Windows(usually) use a "hidden" Linux VM

Very easy to use

Dockerfile like a bash scriptBuilding, tagging, and sharing

KUBERNETES

Orchestration for containers

Allows for indirection between servicesSupports horizontal scaling of services

Supports clustering of servers to provideservice scalabilityDeclarative syntax allowing for moreflexibiluty

Combines Docker, Kubernetes and othertechnologies to provide a completecontainer platformProvides a simple developer interface to thetechnologiesManages source to deployment lifecycleautomaticallyProvides automatic application scalingUnifies the management of the technologies
