DevOps automation: CI and Deployment with Jenkins

Agile development and CI are increasingly becoming the de-fact standard for web application development teams. It allows for faster release cycles, and significantly reduces the amount of bugs in a realease if implemented correctly. During this session I will show you how to setup a CI environment using Jenkins and Zend Server, and also how to automate common Zend Server tasks.

   •Why is that important
   o More Features, More Often (Facebook is good example)
   o Competitive advantage to your business
   o Improve the end-customer experience
   o Reduced costs
   o Better quality
   "Deliver faster, with more features and better quality"

   "DevOps is a methodology which helps foster collaboration
   between the teams that create and test applications (Dev)
   with those that maintain them in production environments
   (Ops).
   •Decrease the tedious communication
   o for requirements needed by the application defined by the Devs
   and provided by the Ops"
   •Decrease the efforts from the Ops
   o needed to assure that the code is ready for prime time.
   o Because "it worked on the Devs computer" is not enough!
   •Allow faster response from the Devs
   Cooperation between Devs and Ops

    •Delivery
    "Continuous Delivery is the natural extension of Continuous
    Integration: an approach in which teams ensure that every
    change to the system is releasable, and that we can release
    any version at the push of a button.
    Continuous Delivery aims to make releases boring, so we can
    deliver frequently and get fast feedback on what users care
    about."

    •Automation is King:
    o gives always deterministic and reproducible results.
    o allows faster reproduction of time-consuming tasks
    •Continuous Integration and Delivery
    o Based on some rules
    o With a click of a button
