5. Infrastructure as Code

package "apache2" do package_name node['apache']['package']endservice "apache2" do case node['platform_family'] when "rhel", "fedora", "suse" service_name "httpd" # If restarted/reloaded too quickly httpd has a habit of failing. # This may happen with multiple recipes notifying apache to restart - like # during the initial bootstrap. restart_command "/sbin/service httpd restart && sleep 1" reload_command "/sbin/service httpd reload && sleep 1"

6. Build & Delivery Pipeline

DevOps for Mobile - Challenges


• Mobile Apps are the front-end to a complex(enterprise) back-end systemo Mobile Apps are rapidly becoming a

critical user interface to enterprise systems

Mobile Application Architecture: LinkedIn

http://engineering.linkedin.com/testing/continuous-integration-mobile




• Fragmented Platformso iOS forked when iPad came

out. Android forked multiple times with each vendor, Kindle Fire, Nook…


• HTML5, PhoneGap/ Cordova still cannot fully replace native

Apps in every situationo Mobile Web is not an acceptable

solution. Users want an Appo Hybrid Apps are the optimal solution

for Apps with non-native needs


• App stores add additional asynchronous deployment stepo Continuous Delivery become

‘deliver and wait’

IBM’s Four DevOps Principles

1. Collaborate across

Disciplines

2. Develop and test against

a production-like system

3. Deploy frequently

4. Continuously validate

operational quality

characteristics

Continuous Integration and Continuous Delivery

1.Ensure end-to-end traceability across all assets

2.Practice continuous integration

3.Maintain separate streams for each mobile OS,

SDK supported

4.Use automated build and deploy scripts


Continuous Testing and Continuous Monitoring

5. Test each build on simulated and physical

devices

6. Virtualize and simulate back end services

7. Monitor the deployed mobile app and back end

services’ performance


Mobile App Delivery

8. Governance of provisioning profiles, certificates

and API keys

9. Use a Private Development App Store to test

device deployment

10. Convert user feedback into user stories

Application distribution (for development and test)

A cross platform private mobile application store similar to public app stores but focused on the needs of an organization or a team

Key capabilities:• delivers distribution and

management of mobile applications within a company / teams

• easy distribution of iOS and Android apps within a team

• provides versioning and updates• centralizes rating and feedback

information• controls who can modify or

install an application• easy to install and simple to run

What is Service Simulation and Test Virtualization?

Test Virtualization enables to create “virtual services”:oVirtual Services simulate the behavior of an entire application or system during testingoVirtual Services can run on commodity hardware, private cloud, public cloudoEach developer, tester can easily have their own test environmentoDeveloper and testers continue to use their testing tools (Manual, Web performance, UI test automation)

System dependencies are a key challenge in setting up test environments:Unavailable/inaccessible: Testing is constrained due to production schedules, security restrictions, contention between teams, or because they are still under development Costly 3rd party access fees: Developing or testing against Cloud-based or other shared services can result in costly usage feesImpractical hardware-based virtualization: Systems are either too difficult (mainframes) or remote (third-party services) to replicate via traditional hardware-based virtualization approaches

Test Virtualization is an enabler for continuous Integration Testing

Services, applications, systems are introduced into the continuous integration cycle in a prioritized, controlled fashion.

IBM Rational Test Virtualization Solution for continuous integration

and testing• Avoid time spent installing and configuring software just to discover

basic build issues• Smoke tests can be integrated as part of the continuous integration

process through deployment automation and test virtualization• Smoke test results are made available to the entire team to shorten
