DevOps culture: myths and reality
Clearing out the myths, then looking at what actually grew at scale
Slide contents
1. DevOps culture: myths and reality
Clearing out the myths, then looking at what actually grew at scale
2. The myths first, then what practice produced
What we'll cover
Myths: who, what, how
Reality: business and IT
Teams and maturity
Conclusions
3. 01. Myths
Who, what and how — three ways to miss
4. There is no such thing as a devops person
What people call one
Not a single person
Not an org unit next to dev and ops
Not the person who knows how to do everything
Not the old sysadmin, and not a dev who runs CI/CD
5. Devops gets swapped for its own form
What it gets passed off as
Not a set of the right fashionable technologies
Not another name for ITIL/ITSM
Not just a buzzword about development culture
6. Quick moves do not buy a culture
How to «do devops» from the outside
Consultants who preach about culture
Consultants who pitch fashionable technologies
Consultants who outsource CI/CD into a black box
Buying an external team wholesale
7. 02. Reality
How it started and what it turned into
8. Infrastructure becomes an internal product
9. Engineering provides shared services
IaaS — Infrastructure-as-a-Service
PaaS — Platform-as-a-Service
DBaaS — Database-as-a-Service
Tooling · monitoring · testing
10. Core and engineering form the platform team
11. 03. Teams and maturity
The Team Topologies reading
12. Teams use three interaction modes
13. Scale and maturity shape team design
14. 04. Conclusions
What to take with you
15. Devops is about joining development and operations
And about how that looks at different scales
Devops is an overloaded term
It is surrounded by a lot of myths
At its core it joins development and operations
At large scale: stream-aligned plus platform teams, with the platform teams building a PaaS
At small scale: teams are better off taking a cloud PaaS
16. What to read next

The «Team Topologies» book — with a three-part summary
An article on product and platform team collaboration
An article on the limits of reusing shared solutions
