[Update based on the panel review]

Inspired by Martin Fowler's introduction to micro services (https://www.youtube.com/watch?v=wgdBVIX9ifA);

The demo will introduce the "ABC"s of the transition to micro services. We will refer to the Hadoop Distributed File System open source and demonstrate to (re)design the NameNode module as a micro service. This will introduce the three primary challenges and their possible solutions as in;

1. Componentize using Services instead of the conventional componentization using the design

2. Data segregation using an event driven framework to separate the centralized data across services

3. Accessing a micro service as a web service instead of an orchestrated access; the delegate & facade patterns will be demoed to loosely couple the interfaces

 

The demo will conclude with a listing of the next steps in transition, which need to be considered after the primary challenges are addressed.

 
 

Outline/Structure of the Demonstration

[Update based on the panel review]

Introduction (5 mins)

Introduce the three primary challenges and their possible solutions as in; (3 * 10 = 30 mins)

1. Componentize using Services instead of the conventional componentization using the design

2. Data segregation using an event driven framework to separate the centralized data across services

3. Accessing a micro service as a web service instead of an orchestrated access; the delegate & facade patterns will be demoed to loosely couple the interfaces

 

The demo will conclude with a listing of the next steps in transition, which need to be considered after the primary challenges are addressed. (5 mins)

Learning Outcome

Understand the fundamental principles of micro services, and the techniques to transition a monolith to micro service. Demo-based learning in a hands on setup using a well known open source example.

    There is growing interest in learning more about Agile HR and its impact on individuals, teams and organizations.

    It is important to separate fact from fiction: What are the real threats and opportunities of bringing Lean | Agile values, principles, and practices to HR? What can we expect in the future? Through anecdotal evidence and case studies, the session will explore the potential of Agile HR as well as provide guidance on how to approach the transformation.

     Issues covered in the presentation include: information on how to embrace the new talent contract, create inspiring, engaging, and fun places of work, shift to an iterative performance flow, take the issue of money off the table, support growth within an Agile enterprise.

    Fennande van der Meulen / Maartje Wolff - The Power of Purpose - workshop on How purpose drives employee happiness and company results

    90 Mins
    Workshop
    Beginner

    Having a clear purpose in both life and work is essential to happiness. And, science and business support this view. Companies with a clear purpose perform better than companies without. Purpose is increasingly seen as the key to navigate the volatile and complex world we live in. And, people with a purpose in their live longer and are healthier. However, finding your purpose, your personal and companies purpose, is not an easy task. In this workshop we discuss what purpose means and key elements of a sustainable and meaningful purpose. We elaborate the four steps to identify the company purpose and how to build your business around it.

    Total cost of ownership of the Investment Bank IT portfolio is way too high. Business is also keen in getting high responsiveness from IT. There is high desirability from all stakeholders in changing the way IT work. Based on a value stream analysis, key  aspects that impede speed and value are identified. Common and prominent impediments identified are silo, handovers, local optimization, manual and inefficient software engineering.  Principles and practices of DevOps seems to be an excellent fit for this change. This means new capabilities for IT workforce, new operating model, new way of measuring, new way of aligning with other corporate groups like security etc.  This session is a journey in progress of IT transformation using DevOps as core theme.  Where to begin? What to change? How to create capabilities? How to onboard teams into this wave? How to sustain? Where are we now? Where we want to reach? Lessons learnt?

    Woody Zuill - Mob Programming: A Whole Team Approach

    45 Mins
    Talk
    Intermediate

    Mob Programming is a development practice where the whole team works on the same thing, at the same time, in the same space, and on the same computer. It is a whole-team approach to doing all the work the team does including designing, coding, testing, and working with the customers, users and other stakeholders. This is an evolutionary step beyond pair programming and accentuates face-to-face communication, team alignment, collaboration, and self-organizing team concepts of the Agile approach to software development.

    Mob Programming can be a highly effective approach to software development. There are numerous teams doing Mob Programming all over the world, including distributed teams, and there has been a great deal of positive reports of success. Please join me as I share how the concept got started, the benefits, techniques we use, and some of the problems we've faced.

    Nayan Hajratwala - Refactoring Legacy Code Guided by Simple Design

    45 Mins
    Demonstration
    Intermediate

    Are you frustrated by the many trivial examples that show up when you google "refactor legacy code"? How do you translate these examples to your real-world code base? Sometimes it's just easier to give up on the refactoring and increased test coverage, reserving these techniques for the ever elusive greenfield project. To help you with this dilemma, Nayan will walk through a real legacy Java code base, and perform some safe refactorings required to bring the code under test. All of this will be done under the guidance of the Four Rules of Simple Design (Pass the tests, DRY, Reveal intent, Minimize moving parts).

    "The higher you go in an organization, the more your suggestions become interpreted as orders." - Marshall Goldsmith

    An Architect garners a high level of authority by being an expert. People will follow their lead. But what if the Architect is wrong? They will follow right off a cliff.

    How do we get people to think like the Architect? Use the principles of Intent-Based Leadership to decouple the success of your project from the personality of the architect. By creating clarity around architectural goals and by engaging people in problem solving rather than defining rules and standards we can divest control and create an organization of leaders.

    Howard Deiner - Legacy Code Retreat - Uncovering Better Ways of Dealing With Legacy Software By Doing it and Helping Others Do It!

    480 Mins
    Workshop
    Intermediate

    In his book “Understanding the Four Rules of Simple Design”, Corey Haines lays out the basics for getting people together for a day and practice coding better. Unhappily, many of us have to deal with legacy code in our daily lives, and find ourselves frustrated when we try to make legacy code better. J. B. Rainsberger has started a variation on on Corey Haines’ code retreats, making them more practical for legacy code practitioners. I’d like to extend that pattern and have retreat for those of us who work legacy code in Java often.

    We will learn and practice the classic Michael Feathers dance of

    1. Identify change points
    2. Find an inflection point
    3. Cover the inflection point (break external dependencies, break internal dependencies, write tests)
    4. Make changes
    5. Refactor the covered code.

    By the end of the day, in addition to being tired and completely ready to put away our laptops forever, we will have gained valuable insights and practical experience with a topic no one likes to talk about - getting better working with legacy code!
