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.
