Rollout

DevOps is to deployment what agile is to software

development.

Automate

Tools

Maven + Jenkins + Bash

We rolled out!

• Are we done now?

• Or did it just start... ?

Business Value

• Development creates business value.

• Business value is rolled out.

• B(n) = B(n-1) + B(r).

How do I get to a Common System State?

DevOps@Runtime!

Let’s give root to all developers?!

Let’s build up a DevOps Department?

It’s DEVops not OPSdev.

Do classic Dev and Op Roles still exist?

DevOps

Contra

• Just another hype?

• Costs money?

• I need to learn puppet, chef, ...?

• Developers are not able/not willing... ?

• Sysadmin will manage it. Alone. Somehow.

What does DevOps bring to the table that makes it unique?

DevOps is not the end of road, it’s the road itself, and

each step on this road makes your life easier.
