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


“The competition have released my idea already *#¡!” What’s taking so long !!

NOT


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


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

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

2012
