● 20+ years doing engineering ● 12 years on management ● Always involved with dev and ops, whatever paid the bills ● Felt uncomfortable with the term devops ● Wrote a book "Devops Toolbox" ● Still uncomfortable My story with devops

What do we do ?

Cardinal sins of collaboration

Lack of awareness

"I just work here" Indifference

"Let's do it manually, we can prioritise automation and tests later" Wrong priorities

"What do you mean by 'it seems slow' ?" Stubbornness

"I'll bring the production issues to our planning and let you know if we can help" Sloth

Act 1 - Delivery - 2004/2007 ● Manually deploying systems depended on sysadmins ● Artifacts created manually ● QA OK manifest required ● Changes through ssh, per server ● Personal relationships dictated success ● ITIL

Act 2 - Configuration Management - 2008 ● From repository to production ● Server state control ● Sysadmins coding ● GIT ! ● Visible Ops ● Learning this budget thing

Act 3 - Virtual Machines - 2009/2013 ● Netflix style - baking XEN images ● Configuration management on bootstrap, not runtime ● Metrics ! ● Few sysadmin required ● Complexity ● Lock-in

Act 4 - Cloud and Kubernetes ● $$$ ● Tsuru as dev environment ● Why not roll this new kubernetes thing ? (~ 2015) ● Too raw, let's build Teresa (2015/2016) ● Still seemed a solution looking for a problem, too complex ● Teams would spend months fiddling with it, something was off. Where are the sysadmins ? ● Nubank's invisible kubernetes just works wtf

Act 5 - What next ? ● Cloud is a commodity, Undifferentiated Heavy Lifting ● Cost management, cloud economics ● Data Engineering ● Security ● Tooling beyond CD ● Metrics beyond … metric collection systems ? ● Automation that lasts

Don't be afraid of breaking things
