20. Culture vs Tools

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

22. Why won’t we be able
tof fix it ?

23. Because the IT industry is
awesome at breaking
things

24. 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
●
Learn the Language
●
Automate the steps
●
Speed up 1000x

25. Agile is dead ?
●
Waterfall
●
Watermill
●
Jira & Standups
●
SAFE

26. Agile is dead ?
●
People over Process
●
Empowering Teams
●
Less
●
Scrum
●
Kanban

27. Who killed #devops ?

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

29. 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

31. #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

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

33. 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 !!

35. 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 :(

36. YOLO Engineering
●
Startup
●
VC
●
Exit Strategy
●
Actual Business
●
Real Customers
●
Survival

37. 10 years later

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

●
What database ? Where to store the
data ?
●
Security ? What distro is this even ?
Bad Cows ?
●
How do we monitor his ?
●
Backups ?
●
How did you build this ?

39. Yes, we can fix it ..
