  • Accelerating Product and Service Innovation

    What Is DevOps for you?

  • Accelerating Product and Service Innovation

    Sometimes people come with this

  • Accelerating Product and Service Innovation

    And this is what we often hear on enterprises

    DevOps? We already do that. Call the DevOps team here to talk with this guy - Business Savvy Executive, thinking that DevOps is just a new team

    We have a Continuous Integration environment here, we just need to convince people to use it - Early promoted IT Manager, coming from a successful IT project

    We have a Release Process that is too much rigid, this will never work here - Developer or Operations guy (pick any), helpless about his future

    Help me Obi Wan Kenobi, you're my only hope - Princess Leia

    Disclosure ALL OPINIONS ARE THEIR OWN! (Phrases and people can change at your own will)

    The Hard Truth There is no Right way to do DevOps

  • Accelerating Product and Service Innovation

    What you need to realize is that a DevOps approach...

    Is a cultural change on how teams work and interact with each other, inside a well structured process

    Requires a collection of principles and techniques to set the pace, maintain standards and lower the chances of drifts

    ... Implements a lot of practices, to continuously and consistently apply the techniques

    Make usage of tools, to help people do their jobs better, apply the techniques and practices and to monitor all the environment

    All of this to deliver the consistency, communication, collaboration, transparency and feedback needed by the Enterprise

  • Accelerating Product and Service Innovation

    Executive leadership is vital

    C-Level, VP, Higher Manager (Higher is better) Have power to put everyone on the same room

    Can help break the silos and bring people in

    Make connections between silos and keep the path clear to move forward

    Defend the DevOps initiative in front of others executives and on meetings

    Advocates on culture change ...

    but all of this does not mean nothing if PEOPLE do not ENGAGE

  • Accelerating Product and Service Innovation

    Culture change should be top level priority

    Change the culture to a culture of change. - Joseph McKevitt

    This is especially difficult on the Enterprise, where a lot of people have different responsibilities, departments are silos and different practices are scattered

    ... and don't forget that there are political reasons too!

    For successful DevOps adoption at the enterprise you must engage everyone involved From Enterprise Architecture to Operations

    They must perceive the value that the enhanced collaboration, communication and transparency of a DevOps Strategy can bring to them.

    This is why the cultural barrier is one of the most difficult challenges and should be a top priority for rolling out DevOps at the Enterprise.

  • Accelerating Product and Service Innovation

    1st Proposal

  • Accelerating Product and Service Innovation

    What we found

    The Good

    A well established SCM + Issue Track + Continuous Integration environment

    Teams that were using this environment and are getting great results

    The Bad

    Some teams did not get any perception of value added by adopting this solution

    Others teams did not have time to make necessary adjustments and migrations to use this environment

    Some teams did not even know that threre is such environment

    The Ugly

    No Executive Sponsorship

    No clear communication and collaboration with testing and operations teams

  • Accelerating Product and Service Innovation

    First Bussines Challenge: Prove Yourself

    Business Input: I do not believe you!

    Challenge: To Prove DevOps value

    Strategy: Find a project to be our pilot

    What worked:

    Found an Agile team that embraced the challenge;

    We partened with them and created a War Room;

    Deep understanding of the enterprise culture and who are the key players;

    After 3 months, they raised productivity more than 30%

    What don't worked well:

    Operations not fully engaged

    No corporate standard for SCM and Versioning

    Different deployment scripts for the environments and platforms

    Business Outcome: Good Job, let's see what happens when we work at scale!

  • Accelerating Product and Service Innovation

    After the pilot result, a lot of teams started to ask how they could participate

    Followed an Agile approach, with releases at each 6 months, aligned with enterprise strategic objectives

    Each release was broken into small deliverables (1 month each) that should:

    Introduce some practice, technique and / or tool to the program

    Must be put on practice by at least one team

    Should address and solve a real business challenge

    After the end of each delivarable, we make a retrospective:

    What worked

    What did not worked

    What could be improved

    What must be changed

    Second Bussines Challenge: Present your strategy

  • Accelerating Product and Service Innovation

    Dev + Ops Working together for business benefit

  • Accelerating Product and Service Innovation

    Infrastructure Change Management

    Tools chain:

    Development Eclipse

    Plan, Track and SCM Rational Team Concert

    Software Definitive Library Rational Asset Manager

  • Accelerating Product and Service Innovation

    Build Pipeline

    Tools chain:

    Development Eclipse, Rational Application Developer or Rational Software Architect

    Plan, Track and SCM Rational Team Concert

    Continuous Integration and Build Automation Rational Build Forge

    Software Construction Apache Maven and Apache Ant

    Software Quality Testing SonarQube

    Software Security Testing IBM AppScan Source

  • Accelerating Product and Service Innovation

    Software Definitive Library

    Continuous delivery is about putting the release schedule in the hands of the business, not in the hands of IT. - Jez Humble

    Runs immediately after the Continuous Integration QA phase

    Publishes the resulting artifacts to SDL

    Tools chain:

    Build Automation Rational Build Forge

    Software Definitive Library Rational Asset Manager

  • Accelerating Product and Service Innovation

    Metamodel for Applications

  • Accelerating Product and Service Innovation

    Deployment Pipeline

    Can be run at any time (including just after the delivery phase as part of the build pipeline) for a published application.

    Tools chain:

    Deployment Automation IBM UrbanCode Deploy

    Software Definitive Library Rational Asset Manager

    The primary goal of continuous deployment is not to deploy continuously. It is to be able to deploy continuously. - Paul Klipp

  • Accelerating Product and Service Innovation

    Delivery Pipeline

    Path followed by an application through its lifecycle

    You can quickly ask to the Software Definitive Library which version is deployed where

    Closing the gap

  • Accelerating Product and Service Innovation

    Ask the Right Questions

    What are you trying to accomplish?

    What is your DevOps strategy?

    What are your business drivers?

    Who are your customers?

    What are your objectives?

  • Accelerating Product and Service Innovation

    Stay focused on the core principles

    Focus on IT business value stream flow and created a shared vision of the whole

    Understand, improve and amplify your feedback loops

    Create a culture of Continual Experimentation and Learning

    Identify the bottlenecks and constraints

    Build a culture of collaboration and respect across your enterprise

    Focus on the principles and adapt the practices based on the culture of the teams

  • Accelerating Product and Service Innovation

    Engaging strategies

    Mix the teams, put someone from the Development on the Operations team for a limited amount of time and vice versa, so they can fell the pain an
