“I have an absolutely brilliant idea ……”
Now let’s build it!

“The competition have released my idea already *#¡!”
What’s taking so long !!
NOT

Now let’s build “container-ise” it!
●  Who builds the container?
●  Where is its definition versioned?
●  Who schedules the workload?
●  What exactly is in this container?
●  How do we connect containers
together?
●  Where do we make a note of ip
addresses and configure network
routes?
●  How does this container talk to
other “things”?
●  What other “things” are needed?

Here’s our DEVOPS recipe ...
-  First, add a pinch of containers and let it simmer
-  Now, add some Puppet, Chef or Ansible to your liking
-  If cooking for a big group of people, consider using a bigger pot or investing in some Kubernetes or maybe
Mesos
-  Now add some Networking Operations and REALLY bring to the boil
-  Cover with a lid while IT Security assesses what you’ve done. In fact put the whole pot inside another pot and
cover that second pot with a lid too. Then, just for good measure, take the pot stack and finish cooking on your
neighbours hob instead of yours and leave a “dummy” pot on your stove to trick anyone trying to steal your
credit card data.
-  Gently stir until cracks in the architecture appear and then remove from heat and serve
-  All leftovers can be frozen and re-heated for upto 90 days. At that point, your OS and libraries will most likely
need patching anyway, so please dispose of the dish responsibly and START ALL OVER AGAIN ………..

What happens to software over times?
“In a connected system, elements are highly available to each other (via global state, for example). A
modular design has connections deliberately kept to a minimum.
….
During the takeoff phase, the team is constantly trying to add value by increasing the chance of survival.
During the cruise phase, reducing costs adds the most value. A different mix of activities goes into achieving
these different goals.”
Kent Beck August 12th, 2009 in Responsible Development, Startups

What happens after deployment ...

“I have another absolutely brilliant idea ……”

Containers Pre-date the Docker Hype
Google started
Linux container
effort “Control
Groups”
Added to the
Linux Kernel in
2007
Cloud Foundry
uses Linux
container
technology -
“Warden
containers”
early 2012
Docker is like
github for
container
images
Docker joins
Cloud Foundry
Foundation
Google, MSFT,
IBM working on
orchestration of
multiple Docker
containers
2006 2014
Cloud Foundry has been using container
technology pre-Docker
