14. Tools will not fix your broken
culture
Tooling hype is not helping

15. Culture vs Tools

16. The vendors struggle
Selling “devops”
●
Is hard
●
Is selling Culture
●
Is selling change
●
Doesn't scale
●
Doesn't get
renewals
You can't buy
DevOps, but
you may need
to sell it.
Ken Mugrage

17. Why would there
not
be a future ?

awesome at ruining great ideas

23. Who killed #devops ?

24. We Broke the Tools
●
7 tools for your devops stack
●
Puppet vs Chef vs Ansible
●
Docker , the Ultimate
“Devops” Tool
●
Implement all the tools ..

25. Recruiters Killed #devops
●
It's not a job title.
●
Is it a developer ?
●
Is it an ops engineer ?
●
Is it a system engineer writing code ?
●
Is it a developer running operations ?
●
My “Pimp” tells me I`m a #devops Engineer

27. #devopsteam
●
It's not the team running tooling
●
It's not the team in charge of delivery
●
It's not yet another silo between devs and
ops

28. There is no such thing
●
Who is
certified ?
●
By who ?

29. Certification killed everything
●
ITIL => misses the goal
●
Scrum => makes it a procedure
●
Devops => the biggest scam of them all
●
For the cause of education ?
●
Devops “insert your tool here” Certifcation ?
●
Certification = Vendors milking users
●
You can’t standardise it either !!

30. Sales/Marketing people
broke devops
●
Devops Tools
●
Devops Certified Tools
●
The Ultimate Devops Tool
●
Lots of people trying to make dishonest money on a grass root movement

32. Change Management &
Resistance
●
20 – 60 – 20
●
20% Early adopters , find your
peers
●
60% Will wait , but adopt slowly
●
20%

33. #enterprise devops
●
“You can only change small organisations”
●
“You can't change a large organisation”
●
“You need to do things different“
●
There is much more to change
●
It takes longer
●
The resistance is bigger
●
“The antibodies kick in”

34. #enterprise devops
●
Naming things is hard
– Naming things confused people
– Vendors have ruined the term
– Huge effort to explain reality
●
Set your goals and name them
– Common name
●
Don’t call it Spotify Model either

35. YOLO Engineering
●
Startup
●
VC
●

Business
●

37. Dev Ooops #container edition
●
“Put this Code Live, here's a Docker

data ?

Security ? What distro is this even ?
Bad Cows ?

How do we monitor his ?
●
Backups ?
●
How did you build this ?

40. Teaching people

41. A long Journey
●
We are nowhere close to being finished..
– 2-5 year journeys are not uncommon for large
orgs

New people onboard

New technologies need to be embraced

44. Every 18 months, automate yourselve out of your job
Someone at Google, longtime ago

45. It's not about the tools
It's about change
It's about the people

46. Time to stand up against
●
Broken Certification
●
Broken hiring processes
●
Broken Outsourcing
●
Accepting work with no
realistic budgets

47. Devops is here to stay,
New tools and technologies will appear
But collaboration will remain a
requirement

48. The future is here,
it's still not evenly distributed
Yet,
and may never be

49. Devops is here to stay,
New tools and technologies will appear
But collaboration will remain a requirement
