4 What is DevOps?

5 Addressing delivery challenges Water-SCRUM-Fall? Customers Line of Business Dev & Test Teams Operations Team Gap Gap Desire for fast and continuous innovation Requirements Code & Tests Business Services Addressed by... Addressed by... Agile Dev Dev Ops

6 Key Concepts 1. Continuous Integration 2. Continuous Delivery 3. Continuous Test 4. Continuous Monitoring 5. Infrastructure as Code 6. Build and Delivery Pipeline

7 1. Continuous Integration

8 2. Continuous Delivery

9 3. Continuous Test

10 4. Continuous Monitoring

11 5. Infrastructure as Code package "apache2" do package_name node['apache']['package'] end service "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"

12 6. Build & Delivery Pipeline

13 DevOps for Mobile Challenges

14 DevOps for Mobile Challenges Mobile Apps are the front-end to a complex(enterprise) back-end system o Mobile Apps are rapidly becoming a critical user interface to enterprise systems

15 DevOps for Mobile Challenges Fragmented Platforms o ios forked when ipad came out. Android forked multiple times with each vendor, Kindle Fire, Nook

16 DevOps for Mobile Challenges HTML5, PhoneGap/ Cordova still cannot fully replace native Apps in every situation o o Mobile Web is not an acceptable solution. Users want an App Hybrid Apps are the optimal solution for Apps with non-native needs

17 DevOps for Mobile Challenges App stores add additional asynchronous deployment step o Continuous Delivery become deliver and wait

21 DevOps Best Practices for Mobile Apps

22 DevOps Best Practices for Mobile Apps 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

23 DevOps Best Practices for Mobile Apps 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

24 DevOps Best Practices for Mobile Apps 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

25 Continuous Integration and Continuous Delivery 1. End-to-end Traceability, across all ios Developer Components Android Developer Deliver App Code Source Control Build Library Fetch Automate Source Artifacts Deployable Artifacts Enterprise Services Developer

26 Continuous Integration and Continuous Delivery 2. Practice Continuous Integration Mobile App Developent Teams Enterprise Services Developent Teams

27 Continuous Integration and Continuous Delivery 3. Maintain separate build areas for each SDK version <manifest xmlns:android=" > <uses-sdk android:minsdkversion="4" android:targetsdkversion="15" />... </manifest>

28 Continuous Integration and Continuous Delivery 4. Automated Build and Deploy scripts Automated Scripts

29 Continuous Testing and Continuous Monitoring 5. Test each build on each supported device

30 Continuous Testing and Continuous Monitoring 6. Simulate Back-end Services Mobile App Third-party Services App Under Test Third-party Services Test Environments to Production Actual Service Simulated Service Mobile App Data Warehouse Directory Identity Portals Mainframe Enterprise Service Bus Heterogeneous Environments

31 Continuous Testing and Continuous Monitoring 7. Monitor deployed apps and back end services performance

32 Mobile App Delivery 8. Governance of provisioning profiles, certificates and API keys

33 Mobile App Delivery 9. Use a Private App store to test device deployment

34 Mobile App Delivery 10. Convert App Store feedback into user stories

53 IBM s DevOps for Mobile Solution Service Virtualization

54 Routing Service What is Service Simulation and Test Virtualization? Public Cloud Mobile App Under Test Collaboration Third-party Services Portals Data Warehouse Directory Identity File systems Mainframe Content Providers Archives Private Cloud Enterprise Service Bus Heterogeneous Environments Business EJB Partners Shared Services Messaging Services Capture & Model Databases Mobile App Under Test Mainframe applications Third-party Services Packaged apps, messaging services, etc. Virtual Services 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 fees Impractical hardware based virtualization: Systems are either too difficult (mainframes) or remote (thirdparty services) to replicate via traditional hardwarebased virtualization approaches Test Virtualization enables to create virtual services : ovirtual Services simulate the behavior of an entire application or system during testing ovirtual Services can run on commodity hardware, private cloud, public cloud oeach developer, tester can easily have their own test environment odeveloper and testers continue to use their testing tools (Manual, Web performance, UI test automation) 54
