DevOps

“You keep using that word. I do not think it means what you think it means”

-Inigo Montoya (The Princess Bride)


Why DevOps?

◆ Efficiency - Faster time to market

◆ Predictability - Lower failure rate of new

releases

◆ Reproducibility – Version everything

◆ Maintainability - Faster time to recovery in the

event of a new release crashing or otherwise

disabling the current system

Break down the wall between development and operations

What is DevOps?

It’s not a team or title … it’s a pipeline.


DevOps is …

More collaboration and automation between the development and operations teams = larger pipeline


DevOps is …

Remove the hand offs – streamline the process, challenge everything that doesn’t add value.


DevOps

One team cannot do it all …

Must be a joint collaboration effort!

Development + CM + DBA

Create reproducible databases and data extracts just like

application code … but it’s a lot more complex.


Development + CM + DBA

Why database migrations?

◆ What state is the database in on this

machine?

◆ Has this script already been applied or

not?

◆ Has the quick fix in production been

applied in test afterwards?

◆ How do you set up a new database

instance?
