“Gartner predicts that in less than three years, 35% of enterprise IT expenditures will happen outside of the corporate IT
budget.”
“results of PricewaterhouseCoopers' Digital IQ Survey indicate that at 100 of
the companies PwC ranks as "top performers," IT controls less than 50% of
corporate technology expenditures.”http://www.computerworld.com/s/article/9226415/The_Upside_of_Shadow_IT?pageNumber=1

WHAT IS DEVOPS?And why should you care?
DevOpsGuys
Defining Devops I
“The term “DevOps” typically refers to the emerging professional movement that advocates a collaborative working
relationship between Development and IT Operations, resulting in the fast flow of planned work (i.e., high deploy rates), while simultaneously increasing the
reliability, stability, resilience and security of the production environment.” – Gene
Kim http://itrevolution.com/11devops/

He goes on to say
“…while simultaneously increasing the reliability,
stability, resilience and security of the production environment.”
– Gene Kim

Defining Devops II“I’ll tell you EXACTLY what DevOps means.
DevOps means giving a sh*t about your job enough to not pass the buck. DevOps means giving a sh*t about your job enough to want to learn all the parts and not just your little world.
Developers need to understand infrastructure. Operations people need to understand code. People need to f**king work with each other and not just occupy space next to each other.” - John E. Vincent (@Lusis)

Products not Projects

Embrace Chaos!“One of the first systems our engineers built in AWS is called the Chaos Monkey. The Chaos Monkey’s job is to randomly kill instances and services within our architecture. If we aren’t constantly testing our ability to succeed despite failure, then it isn’t likely to work when it matters most – in the event of an unexpected outage.”

DevOps Transformation
• Don’t attack the Silos– “Make more awesome”
• Use the CAMS framework & the 3 Ways as guiding principles
• Start small & iterate• Standard change management
practices… but remember culture, culture, culture!

What DevOps ISN’T
• Not a “free-for-all”• Not a return to the “pre-ITIL cowboys
days”• “Developers managing Production”– http://blog.devopsguys.com/2013/02/17

DEVOPS & RECRUITERSA difference in emphasis?

DevOps Job Board Keywords
DevOpsGuys
“DevOps” Whitewashing
• Most of the job ads aren’t really “DevOps” jobs– It’s a SysAdmin job that someone’s
stuck a DevOps label on…
• Challenge the customer’s requirements– Puppet and Chef on the same advert?
• DevOps isn’t a synonym for Automation (remember C.A.L.M.S!)
DevOpsGuys
Understand the Big Picture
• “DevOps” Transformation
• Digital Transformation• Cloud Migration
