Dev or Ops?
6 Days after a successful deployment, the server experiences high load.

Dev or Ops?
There is an issue with the build server.
Code isn’t building.

Dev or Ops?
Software is deployed to the test environment.
You can’t login to the application.

Dev vs. Ops

“It works on my machine...”

“It’s not the server, it’s your code.”

What is the role of Dev and Ops?

What are the roles of Devs and Ops?
Dev
Create change
Add or modify features
Ops
Create stability
Create or enhance services

We Have A Problem...

The Problem
Disconnect between the groups
Results in conflict and inefficiencies
Devs don’t deploy consistent software
Ops are motivated to resist change
Development process is Agile
Operations process is Static

And we are missing the point of it all...

We are all here to ENABLE business

So What’s All This Change?

Change
Is required for business
Doesn’t mean outages
Should be exploited and not feared

Change shouldn’t mean fire fighting

DevOps To The Rescue!

What is DevOps?
“DevOps is an approach to bridge the gap between agile software development and operations” – agileweboperations.com
Collaborative Mindset of Devs and Ops
It’s what Agile is to software development
C.A.M.S.

Culture

Culture
Relationships
Engage early, engage often
Bust Silos TM
Be open
Stop finger pointing
Eradicate “last-mile syndrome”

Culture
Communication
Talk is cheap (get out of your chair)
Involve each other in core processes and decisions
Ask Questions
Don’t say “no”
Invite everyone to stand-ups and retrospectives

Automation

Automation
Machines are really good at doing the same task over and over
Consistent and Known State
Fast and Efficient
5 mins/day = 2.6 days/year

Automation
What can be automated?
Builds
Deployments
Testings
Monitoring
Self-healing
System rollouts
System configuration

Metrics

Metrics
Capture, learn, improve.
Assists in:
Capacity Planning
Trend Analysis
Fault Finding
Simple as saving Tomcat access info
Plotted on a graph over time

Metrics

Sharing

Sharing
Share Ideas
Share Metrics
Ops: Give devs shell access
Devs: See what technology can be leveraged
