T-Mobile Case Study: Looking to Build a Foundation for DevOps

DevOps

Abstract

There are ways to start on the path of having

a positive impact on the organization’s ability

to deliver application more quickly with quality.

Standardized configuration management,

service virtualization, automated code

deployments and automated test are

foundational to any DevOps or related initiative.

Typical IT challenges we’re facing


Need to get features out faster.

Code delivery takes too long.

Trying to move faster increases “code debt.” (We’ll fix it later.)

Conflict in goals between Ops and Dev (perception of “Risk”)

Transformation/Change can be viewed as job “insecurity.”

IT needs to respond FASTER and cost LESS. T-Mobile and the magenta color are registered trademarks of Deutsche Telekom AG. © 2014 T-Mobile USA, Inc.

STANDARIZED CONFIGURATION MANAGEMENT


But, we knew we needed to DO MORE.


Release notes were a manual, tedious process

Environments can’t be built fast enough and different teams support different environments.

Deployment process varies from app to app.

Couldn’t even consider continuous delivery

The need for more deployments and faster time- to-market for features keeps increasing.


C U L T U R E It’s a hard thing to overcome.


A technical foundation to support A DevOps and CD model


Service Virtualization, a great next step


We could get wins that benefited multiple groups.

Success would help some teams to start seeing the potential.

One of our key customers—Retail Sales—would benefit.

Development could start doing more parallel development.


Finding the RIGHT first project(s)


Keep projects smaller in scope to start.

Focus on goals that are clear and more readily understood.

Look for wins that can also benefit multiple teams.

Start to build “believers.”


Put a lead and two other senior developers on to start.

After about four months—expanded to four onshore, two offshore developers

Created a Center of EXCELLENCE

developers

On shore

Off shore

four months


Why developers?

Have more ways to solve problems Will have more of an architectural view/design

patterns They can write code to solve problems and to link tools

together. Allowed me to be nimble

None had previous experience with SV but in under a week we were virtualizing services.


Application training environments (something new)

Partner integration Performance testing

Development has started doing more parallel development.

“Changes how we hire people” –Sales Operations

Provided an environment for staging/prod configuration testing.

DEPLOYMENT AUTOMATION


The key to any process—including an automated one— is repeatability, which requires consistency.

Once the core deployment patterns are built, other less experienced folks can copy.

Easier for teams to see how the deployment flow works

Wanted to avoid hundreds of thousands of lines of scripting code

The ability to utilize a modern workflow tool for deployment automation was key for us.


Architected the core solution first including:

Evaluated in parallel deployment tools

Built the tools to integrate and manage multiple environments—more than just using deployment tools.

Started building the design patterns

• Application configuration and monitoring standards

Found our first project to demonstrate end-to-end build, deploy and use SV to shorten dev cycle.

• Coding documentation


Getting Other Teams Onboard


Evangelize and champion the successes.

Get teams to partner together—especially development and operations.

Need to plan for success and have thought about how to roll out when adoption occurs

Find transformational-minded people and get them involved.

DevOps/CD is a term that more and more folks will have “heard” of, it will have “recognition.”

Success is contagious—especially when it is being rewarded by management.


Thank you!
