@krisbuytaert
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

@krisbuytaert
This industry is
great at killing awesome
things

@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

Speed up 1000x

@krisbuytaert

●
Waterfall
●
Watermill

SaFe

@krisbuytaert
Who killed #devops ?

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

@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 ?

@krisbuytaert

@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

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

@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 !!

@krisbuytaert

@krisbuytaert
#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”

@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 :(
