Defining Devops II
“I’ll tell you EXACTLY what DevOps means.
DevOps means giving a sh*t about your job
enough to not pass the buck.
DevOps means giving a sh*t about your job
enough to want to learn all the parts and not just
your little world.
Developers need to understand infrastructure.
Operations people need to understand code.
- John E. Vincent (@Lusis)
