@krisbuytaert 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 ● Learn the Language ● Automate the steps ● Speed up 1000x

@krisbuytaert Agile is dead ? ● Waterfall ● Watermill ● Jira & Standups ● 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 #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 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 :(

@krisbuytaert Dev Ooops #container edition ● “Put this Code Live, here's a Docker Image ” ● No machines available ? ● 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 ?

@krisbuytaert What have we really learned ?

@krisbuytaert The rise of ● Cargo Culting ● YoloOps ● Resume Driven development ● Hype Driven development

“Success” Stories ● Not always real success stories :( ● Change Happens ● But not company wide

@krisbuytaert A long Journey ● We are nowhere close to being finished.. ● Young organisations become old ● New people onboard ● New technologies need to be embrace

@krisbuytaert Our role tomorrow today ● Teacher ● Student ● Bridge Builder ● Developer ● Troubleshooter ● Evangelist ● Shrink

@krisbuytaert It's not about the tools It's about change It's about the people
