Continuous … Continuous Integration Continuous Delivery Continuous Deployment 2
Definitions ! Continuous Integration ! Each commit or per batch, the source code is : ! Compiled ! Tested ! Deployed on Integration environment ! Continuous Delivery ! Each commit or per batch, the source code is : ! […] ! Delivered to next team (QA, validation, production, …) ! Continuous Deployment ! Each commit or per batch, the source code is : ! […] ! Deployed on Production environment 3

How ? 1- Two things ü Source repository ü One machine to build 9
How ? 2- Many principles to apply : ü Maintain a code repository ü Automate the build ü Make the build self-testing ü Everyone commits more often ü Everyone can see the results of the latest build ü Automate deployment Source : http://en.wikipedia.org/wiki/Continuous_integration 10
Continuous Continuous Delivery Deployment 11
One big difference Continuous Delivery manual 2 1 Team 3 4 5 Source Repository Continuous Integration Server Tests (UAT, QA) Deploy to production Continuous Deployment auto Source : http://blog.crisp.se/2013/02/05/yassalsundman/continuous-delivery-vs-continuous-deployment 12
Samples (for the backend) 1 deployment per day ~10 deployments per day ~25 deployments per day ~50 deployments per day 1 deployment every 11 seconds 2009/2010 13
What about mobile Apps ? ! Continuous deployment, not continuous delivery ! Many factors prevent from doing continuous delivery ! On iOS and WP the Store validation process ! On Android the regression testing process is long ! Facebook is going for crowd testing on Android ! Android Beta Program ! New releases are marketed towards the users and they expect them ! ! “42 new levels for Candy Crush !” ! “A new hero in Clash of Clans !” ! “A new budget feature for my mobile banking app !” ! The emerging standard is going to release every month 14
Why deploy continuously ? ! Improve TTM and feedback in real life IDEAS LEARN FAST CODE FAST DATA CODE MEASURE FAST 15
Meetic sample ! Deploy every day at 4PM to the product team ! Product team come on the open space at 4:30 and give feedbacks 16
And quality ? ! By decreasing deployment size ! Minimize risks ! Reduce the Mean Time To Repair (MTTR) 17
Installing Jenkins ! Manual Installation ! Install Java ! Download jenkins.war ! Start the server ! Directly java –jar jenkins.war ! Or with a Java Web Application Server ! Jenkins is accessible at : http://localhost:8080/ 18
Install plugins 20
Distributed jobs ! Sometimes the CI Server can’t execute the build directly on the server ! For example on windows it’s impossible to build Objective-C source code, you need a Mac for that. ! It’s the master/slave notion execute the build on MASTER SLAVE 21
