Kids, I'm going to tell you an incredible story, the story of

How I met DevOps

Back to the IT dark age

Business | Dev | Ops 3 knowledge silos + 2 wall of confusions

We did a lot of excesses

Over budget, behind schedule, useless features = Sadness

So this is how I did better soft.

The end...

No!!!

Best App. Ever NOT in Prod = USELESS

Dev Vs. Ops

The eternal conflict:

Any change, even a change for the better, is always accompanied by drawbacks and discomforts.

Arnold Bennett

Dev | Ops

Blow that wall away!!

DevOps

It's all about: Cooperation, Facilitation, Delivery

4 values

Culture

Automation

Measurement

Sharing

Culture

OPS who are DEVS who like DEVS to be OPS who do OPS like they're DEVS who do DEV like they're OPS always should be SOMEONE YOU REALLY LOVE

Automation

83% of deployment failures are due to a lack of automation True Story

Measurement

Sharing

What about tools?

Application Release Automation

Infrastructure As Code

Chef Vs. Puppet Vs. CFEngine Vs. Ansible Vs. Script Vs ?

From RCA

To monitoring

To IT Operation Analytics

The Cloud?

Conclusion

DevOps = Extend AGILE scope to OPERATION field. Goal = Go fast and be secure from IDEA to VALUE.
