Abstract DevOps plays a vital role in mobile projects to meet buzz word “faster time to the market” and “faster reaction to the customer” before they ask. It’s a big challenge in mobility as there are multiple mobile operating systems vs multiple OS version in mobile ecosystem. How do we address below challenges? Every three days a new mobile manufacturing company brings new mobiles into market Building mobile apps as fast as with market expectation Testing mobile app on multiple OS vs multiple OS versions Distributing app and notification to stakeholders Monitoring the app statistics, performance and crash analytics This paper talks about addressing the challenges with Mobile DevOps process which involves setting the environment, development, testing, build, distributing app and monitoring the app with continuous integration, continuous deployment and continuous delivery using Microsoft Technology.

Key findings High-performing organizations decisively outperform their lower-performing peers 200 times faster 2555 faster lead time Recover 24 times faster 3 times lower failure change rate High-performing organizations spend 22 percent less time on unplanned work and rework

Interesting data Parameters Fortune 1000 company survey with traditional IT Avg. downtime Cost $1.25b - $2.5b per year Avg. hourly cost of infrastructure failure $1m per hour Avg. Cost of critical application failure $0.5m-1m per hour DevOps process accelerate delivery 100% Avg. Cost % Wastage with Development, Test, Deployment and Operations 25% per year

DevOps DevOps a clipped compound of development and operations DevOps treats Infrastructure as code DevOps is a culture, a practice, and an approach to operations DevOps is using Automation Development Operations QA

DevOps pipeline with Microsoft Technology

Case Study / Implementation

Development - Phase Xamarin is integrated with Visual Studio

Test - Phase Xamarin Test Cloud provides more than 2400 mobile devices on cloud for iOS and Android Automation with Xamarin.UITest

Test Approach Unit Testing/Integration testing with MS Tests Develop UI Workflows on Continuous Integration Testing for nightly builds with Xamarin.UITest Regression Testing for execution on multiple platform Test Pyramid Approach

Build – Continuous Integration Team Foundation 2015 and higher – Check-In Configuration of Gated Check-In with Unit Test Integration Build vNext provides wizard based configuration on build configuration Scheduled Build /Nightly Builds Manual Trigger Manual Trigger Scheduled Build

Distribute & Monitor – Continuous Deployment HockeyApp / Visual Studio Mobile Center Distribute iOS and Android App and alert for new builds Download and upgrade to latest app Monitor Collect User Feedback Collect Crash reports and logs User Metrics Download information User engagement
