Cloud: it’s what we always wanted
Today, our Cloud story is really a container story
Containers can go anywhere
Do anything
Are super versatile
Containers are giving us new opportunities
As long as the answer is “container”
With new performance profiles new systems are emerging

We’re all set on a future with containers
• Containers offer immutability and repeatability
• But there are immediate challenges…
Cloud Computing is not perfect - yet
But who cares about a little rain?

To enable these choices you need new things…
A shipyard to manage the containers
AKA Docker swarm / Kubernetes
Tools to manage the complexities of microservice based systems..
Umm….
Enough tools for you?
More consequences
Quite often containersare full of trash
They don’t behave as expected (or at all)
And debugging is hugely painful
It’s tough being a container developer

The CI/CD Pipeline
Now add more frameworks and languages
Add containers and clouds…
Your development LifecycleRuns on your desk
In a container inyour desktop
In a container inyour CI system
To produce an image …
Doesn’t look very “immutable” does it?

Deployment tools are heavyweight and complex
So the developers use different ones.

The lifecycle is too complex.
So developers use cut-down versions

We have multiple systems of verification
Because we can’t be certain a developers action won’t break the production system

It’s ironic

The person who knows what that the code is supposed to do
Is greatly hampered by the process of delivering the code
Building, testing and deployingis changing too
In the cloud a single server is too high a risk
You don’t want to be left hanging around – waiting for the CI system to come back
All Change: Central server outside the cluster
All Change: Separate pipelines in the cluster
One more..
Containers are not just Docker.Operating Systems are becoming containerizedContainerised OS’s are not configured – they are deployed
We’re entering a new world of substantially increased complexity –many new tools, many new ways of working.
Containers are changing everything about how we work
And the tooling is not keeping up
A little bit more rain than you expected?
It’s not all bad..
help is coming
The CNCF is helping bring direction and structure…
Containers are more than Docker
You ain’tseen nothing
