Kris Buytaert has been involved in DevOps for 10 years, organizing 250 DevOps events across the world. While tools have evolved from things like Puppet and Chef to Docker and Kubernetes, the most important lessons are about culture change and people. Many organizations have paid lip service to DevOps without truly changing culture and processes, and resistance to change remains a major barrier. The future of DevOps is about continual learning and helping others change.

Why we study history ?
●
Because I`m a grumpy old frustrated
developer sysadmin
●
Because I`m an old opiniated guy
●
Because history repeats
●
We need to learn from our mistakes

Culture vs Tools

19. @krisbuytaert
This industry is
great at killing awesome
things

20. @krisbuytaert
Is ITIL dead ?
●
The last mile
●
The men who say no
●
Guardians of Production
●
Friday at 10 am
●
Reducing risk upfront
●
Machines make decisions
●
Lower downtime

Constantly

22. @krisbuytaert
Who killed #devops ?

23. @krisbuytaert
We Did
●
7 tools for your devops stack
●
Puppet vs Chef vs Ansible
●
Docker , the Ultimate “Devops” Tool
●
Implement all the tools ..

24. @krisbuytaert
Recruiters Killed #devops
●
It's not a job title.
●
Is it a developer ?
●
Is it an ops engineer ?
●
a system engineer writing code ?
●
a developer running operations ?

25. @krisbuytaert

26. @krisbuytaert
#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

27. @krisbuytaert
There is no such thing
●
Who is certified ?
●
By who ?

28. @krisbuytaert
Certification kills 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 !!

#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”

31. @krisbuytaert
Most Large Enterprises are not even close to
#devops, #agile
Their culture is so broken they keep lying to
themselves they are
While pushing people closer to BurnOut :(
