The Problem

● Live-Server– Deployed by: Ops

– OS: CentOS

– Deployed with: ● Human Hands● Custom Scripts

– Developed by Ops

The Problem

● Test-Server– Deployed by: Dev

– OS: Ubuntu

– Deployed with: Custom Scripts● Developed by Dev

The Problem

● New Release● Pages and Pages of installation/update instructions

– stop services– database backup

– upgrade DB schema

– upgrade files here

– upgrade some other files there

– again, upgrade DB schema

– ...

The Problem

● Takes very long● Error-Prone

– Oops, i've forgot step 21

– Hm, there was an error with step 17

● Colleague is on vacation

How to fix it?

● Ops and Dev needs at one point the same toolkit.

● Ops and Dev needs to talk with each other● Fail early

– Test machines must have the same configuration and deployment procedure as live machines.
