Information regarding potential future products is intended to outline our
general product direction and it should not be relied on in making a purchasing

Performance is based on measurements and projections using standard IBM benchmarks
in a controlled environment. The actual throughput or performance that any user will
experience will vary depending upon many factors, including considerations such as the
amount of multiprogramming in the user’s job stream, the I/O configuration, the storage
configuration, and the workload processed. Therefore, no assurance can be given that an
individual user will achieve results similar to those stated here.

DevOps is…
A set of principles and values that
facilitate collaboration across
disciplines to…
People

• Enable rapid evolution of Process
deployed business services Information
• Reduce risk, decrease cost, and
improve quality across the portfolio

Three DevOps Principles
1. Develop and test against a
production-like system
2. Deploy frequently
3. Continuously validate
operational quality
characteristics

Mobile DevOps Challenges
• Fragmented Platforms
o iOS forked when iPad came out.
Android forked multiple times with
each vendor, Kindle Fire, Nook…

• HTML5 / Cordova still cannot
fully replace native
• Mobile Apps are typically
the front-end to a
complex(potentially
enterprise) back-end system
• App stores add additional
asynchronous deployment
step

10 Mobile DevOps
Best Practices

10 Mobile DevOps Practices
1. Common team repository, with
version control for all artifacts

2. Practice Continuous Integration
o Have a central Build and Integration server

3. Maintain separate build and
integration areas for each SDK
version supported

<manifest xmlns:android="http://schemas.android.com/apk/res/android" ... >
<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="15" />
...
</manifest>

4. Automated Build and Deploy scripts
o Manage and version the scripts like code
o Make each build reproducible at any time
Automated
Scripts

5. Test each build
o On simulated and physical devices

6. End-to-end Testing:
o Virtualize back end services that are not
available during testing Mobile App

7. Centralized governance of provider
provisioning profiles, certificates and
API keys

8. Monitor deployed app and back
end services performance

9. Use a ‘virtual’ App store to test
deployment devices

10.Create a process to convert Test
user and actual user feedback into
enhancement requests/user stories

What is your DevOps
Maturity?

12 Steps to better DevOps
1. Do your developers and operators communicate the
production realities and the application's requirements?
2. Do you version deployment configuration and scripts
along with your source code?
3. Do you have patterns for platforms and applications,
designed jointly by development and operations?
4. Can your developers launch and destroy production-like
environments from those patterns?
5. Are your patterns based on reusable deployment
configuration scripts?
6. Can you deploy an environment (platform and application)
in one step?
7. Do you deploy your applications daily into production-like environments
and verify them?
8. Do you link bugs and work items to changes in the application and
configuration?
9. Do you associate tickets for production issues with relevant bugs
opened for development to fix?
10. Do you have automated tests to validate your application and platform
function and characteristics?
11. Do you monitor software against expectations after deploying your
application?
12. Do you have a delivery pipeline exposed through a summary
dashboard to assess delivery velocity?
