The Old IT
Old IT doesn’t have a great reputation
Putting the NO in Innovation
BOFH
PEBCAK
Have you tried turning it on and off again?
What if IT was doing exactly what it was asked to do?
Q: But what is the one thing that can get you fired
A: Downtime
Q: How many people in your company think they’re your boss
A: Everybody
Background of high-performing IT managers
Backgrounds
non-commissioned officers
chemical engineers
auditors
What do they have in common?
discipline, process Kevin Behr, Gene Kim, George Spafford
Expectations of IT have changedIT is being asked to be
the grown-up of the corporation
Of course everything think’s we’re arseholes.
Other options now exist: cheaper, faster, consumer-grade
IT now needs to both be innovative AND a grown-up
Three ways to think about IT
Pioneers (Agile)
Settlers (DevOps)
Town Planners (Six Sigma)
—Simon Wardley—see also Gartner, “bimodal IT”
DevOpsDevOps is explicitly without a definition: Not about tools, job titles, process, and not even about Dev and Ops
About empathy, culture, inclusivity, continuous improvement, aligning incentives, removing information hiding, clear responsibilities
Dreaming of an IT that Doesn’t Suck
Effect on IT: End-to-end service delivery teams
Acknowledge old way doesn’t
work
Smart people fix things
Codify into best practices
Establish processes
Processes without context fail
Lifecycle of all thingsInspired by a diagram on Twitter I can’t find at the moment
DevOps is over here
ITIL is over here
New forces shaping learning, shifting power
Open Source
Cloud
SaaS
Social Media
inspired by The New Kingmakers, Stephen O’Grady
Cheaper to Try
Try Before You Buy
Easier to Scale
Knowledge Sharing
Faster Time to Value
Become part of the new business landscape
Old channels failing: tech press, analysts, trade shows, email marketing, Google ads, webinars
50-70% customer decision before talking to vendor
How do people learn anything these days?From their peers (that’s
you)
Become a Pi-shaped expert
Generalist = Printer repair
Specialist = interesting but limited
T-shaped Expert = Generalist with Speciality
PI-shaped Expert
Your “T” must move over time!
Windows -> Storage -> Virtualization -> Cloud -> Flying Cars
GeneralistSpecialist
Interest
CloudCloud is the ultimate AND
SaaS AND self-managed apps
Off-Perm AND on-prem
private, public, AND hybrid
Fighting about definitions (“True Cloud”) has held us back
OpenStack, vCloud Air uses are very different
Effect on IT: IT now a service broker, not an infrastructure owner
Warning:Do not play
Buzzword Drinking Games with
“Cloud”You will get drunk
Cloud Skills
Software development basics & APIs
Linux
Automation and orchestration
Public cloud services
-Scott Lowe
Containers (Docker)Job to be done
VM: utilization for legacy apps (also get isolation, management, BCDR)
Container: rapid, portable deployment for cloud-native apps
destroy/rebuild paradigm
Effect on IT: Docker is seen as a Dev tool, but it’s actually good for Ops (early days)

How do people use Docker?
“for me the value is in trivial repeatability”
“having a fresh image that is easily rebuildable is easier for me to give demos than to spin fresh VMs”
“Most configuration management systems actually make ongoing configuration pretty hard. O… The reality is that once the VM is built there is temptation/opportunity to make ad-hoc changes”
“Bridging a gap with less-technical coworkers” for off-line distribution

Paradox of the grass roots
Virtualization could come from bottom-up
Secretly virtualize a DNS or file server
Start with the low hanging fruit
Start with one person
Cloud, DevOps: all-or-nothing?
Cloud & DevOps require process and cultural changes
But change starts with you
Start a side project
Use a new tool on a new work project
Blog about it
Go to a new user group
Start a brownbag lunch-and-learn series at work
Educate your managers with your results
A few Jedi mind tricks before I leave
Shift from “operator” mindset to “creator” mindset
Keep moving
Do things that charge you up
Release early and often
Be a communicator
Be a collaborator: “Yes, And…” makes you seem smarter
-Gandhi
“If we could change ourselves, the tendencies in the world would also change. As a man changes his own nature, so does the attitude of the world change towards
him. … We need not wait to see what others do.”
-Not Gandhi
“Be the change you wish to see in the world”
