5. Typical ITchallenges we’re facing
T-Mobile and themagenta color areregisteredtrademarksofDeutsche Telekom AG. ©2014T-Mobile USA, Inc.

6. Needto get features out faster.
Codedelivery takes too long.
Trying to move faster increases“code debt.” (We’llfixitlater.)
Conflictin goals between Ops andDev
(perceptionof “Risk”)
Transformation/Changecan be viewed as job“insecurity.”
IT needsto respond FASTER and cost LESS.

8. But,we knew we needed toDO MORE.

9. Release notes were a manual,tediousprocess
Environmentscan’t be builtfastenoughand
differentteams supportdifferent environments.
Deployment process variesfrom appto app.
Couldn’teven considercontinuousdelivery
The need for more deploymentsand faster time-
to-market for featureskeeps increasing.

It’s a hard thing to overcome.

13. We couldget wins that benefitedmultiplegroups.
Success wouldhelpsome teams
tostart seeingthe potential.
One of ourkey customers—Retail Sales—would
benefit.
Developmentcouldstart doing
more paralleldevelopment.

15. Keepprojects smaller inscope to start.
Focus on goals that are clear
and more readilyunderstood.
Lookfor wins that can also benefitmultipleteams.
Start to build“believers.”

17. Why developers?
Have more ways to solve problems
Will have more of anarchitectural view/design
patterns
They can write code tosolve problems andtolinktools
together.
Allowedme to be nimble
None had previous experience with SV but
in under a week we were virtualizing services.

19. DEPLOYMENT AUTOMATION
T-Mobile and themagenta color areregisteredtrademarksofDeutsche Telekom AG. ©2014T-Mobile USA, Inc.

20. The key to any process—includingan automatedone—
is repeatability,which requires consistency.
Once the core deployment patterns are built, other less
experienced folkscancopy.
Easier for teams to see how the deployment flowworks
Wanted to avoid hundreds of thousands
oflinesof scriptingcode
The ability to utilizeamodern workflowtool
for deploymentautomationwas keyforus.

21. Architected the core solutionfirstincluding:
Evaluatedin parallel deploymenttools
Builtthe toolsto integrate andmanage multipleenvironments—more
than justusing deployment tools.
Startedbuildingthe design patterns
• Applicationconfigurationandmonitoring standards
Foundour first project todemonstrate end-to-end build,deployand use
SV to shorten dev cycle.
• Codingdocumentation

22. GettingOther Teams Onboard
T-Mobile and themagenta color areregisteredtrademarksofDeutsche Telekom AG. ©2014T-Mobile USA, Inc.

23. Evangelize andchampionthe successes.
Get teams topartner together—especially
development andoperations.
Need to planfor success andhave thought about
howto rolloutwhen adoptionoccurs
Findtransformational-mindedpeople
andget them involved.
DevOps/CD is a term thatmore and more folks willhave
“heard” of, it will have “recognition.”
Success is contagious—especiallywhen itis being
rewarded by management.
