Devs
Before DevOps
Ops
QA
![Page 8: Implementing DevOps In Practice](https://reader034.fdocuments.us/reader034/viewer/2022042716/55a7a15f1a28ab3f438b481f/html5/thumbnails/8.jpg)
Devs Ops
They build it
Development is single
responsibility
No access to production
systems
“It worked on my machine”
They deploy and run it
Control and operate all
prod servers
Restrict access
On duty rotation
“You mess it up and I have
to wake up when it fails”

What is DevOps?
The DevOps movement emphasizes communication,
collaboration and integration between software
developers and IT operations (New Relic)
The set of cultural norms and technical practices that
enable organizations to have a fast flow of work from
development through test and deployment, while
preserving world-class reliability, availability, and
security. (Gene Kim)
