How EDH was contained!Containerisation and Deis

A New World Order

The ‘what’ and ‘why’ of

Containers

Demo and Examples

What are Containers?

Linux Containers (LXC)

OS level virtualization method for running multiple

Linux systems on a single host.

Resource isolation - CPU, memory, block I/O,

network, etc. (cgroups)

Does not require starting any virtual machines

So, why containers?• Application Packaging

• Bundle code and dependencies

• Run anywhere*

• The 12 Factor App

• Simpler for Operations

• Consistency

• Application Centric View

• Continuous Delivery

• Run same artifact in all environments

Docker

AWS

Next steps - Delivery

PipelineCurrent use as Heroku

Git push deployments

Not ideal CD workflow

Prefer to generate artifact upfront

Deploy Docker Image instead - manage in Registry

Next Steps - something else?

Deis

Thin layer on solid tech

Immature, but convenient

abstraction for now

Exciting things are happening

Kubernetes (Google)

Panamax (Century Link)

Mesos (Apache)
