Hexagonal Architecture Ports&Adapters with J. Martinsson & R. Sanlaville

Feb 10, 2015 by Madalina Botez in  Announcements

Until recently, layered architecture was the most common way of organizing large applications or modules. We’ve learned from practice that it has limitations:

  • business rules tend to escape or be duplicated in UI and/or data layer
  • switching from a database to another is very difficult
  • adding another UI to the application (eg. mobile or smart client) requires heavy changes
  • changing a library used by the application with another is often complex and risky

A new architecture style has appeared in the recent years that tackles this problem: Hexagonal Architecture, or Ports & Adapters. Its intent is to allow more flexibility by cleanly separating business rules from everything else.

Johann Martinsson and Rémy Sanlaville have described the basics of Hexagonal Architecture and then shown an example of such an architecture.

Ansible, AWS & Elasticsearch

Apr 15, 2016

Enjoy the following series of interviews with the speakers, top-notch software crafters from across Europe, joining  I T.A.K.E Unconference, Bucharest, 19-20 May. Discover the lessons learned and what drives them to challenge the known path in their field. 

In today’s news is Phillipp Krenn, developer advocate @Elastic, who spreads the love and knowledge of full-text search, analytics, and real-time data. During his sessions, the attendees will cover the basics of Ansible by setting up a local environment in Vagrant and explore how Elasticsearch stores and interacts with JSON documents.

#1. SHARE TOP 5 THINGS YOU DID THAT HELPED YOU GROW & BECOME THE PROFESSIONAL YOU ARE TODAY

  • Never stop learning: Keep up to date & don’t ignore either tried and tested solutions of the past
  • Participate at local events to learn and get to know other people in your field — meetup.com is a great starting point
  • Build stuff: Find interesting problems to apply and extend your skills
  • Attend at least 1 conference per year to broaden your horizon
  • Your dream job or project is just one interview away; there are way more opportunities than you would think at first, just give it a try

 

#2. What challenges will the participants find solutions to during your sessions @ I T.A.K.E Unconference 2016?

In my Ansible & AWS workshop we will learn how to automate your infrastructure, so you have a reproducible and documented system.
In the Elasticsearch talk we will try to overcome the object-relational impedence mismatch and make developmemt more productive and fun.

 

#3. What else would you like to share with participants?

The best place to learn more about my experience or ask any question is definitely Twitter – @xeraa

#1. Share with us 5 things you did that helped you grow & become the professional you are today

  • I got the chance to work with technology from a very early age (think ZX Spectrum, Intel 8088) and also with assembly language. This taught me to appreciate constraints and never ignore optimization or be lazy.
  • Discovering OSS via the Allegro game library lead me to a wealth of code to analyze and learn from.
  • Getting a job in the IT department at the university while being a student there leading to four years of experimenting with whatever I wanted to.
  • Teaching at the same university.
  • Getting involved in the Drupal community, taking part in the creation of Romanian branch, organizing various camps and teaching Drupal.

 

#2. What challenges will the participants find solutions to during your session at I T.A.K.E Unconference 2016?

How to simplify your development workflow.

 

#3. What else would you like to share with participants

  • I am a very bad theremin player. The theremin was the first electronic instrument ever invented and you play it by not touching it. Check it out, it’s pretty cool.
  • I am passionate about synthesizers, old hardware and horror movies.
  • I am an amateur musician using Gameboys, Commodore 64 sound chips and other retro things. I once played music in the Gara de Nord railway, at the info panel.
  • I like to ride statues (usually of pigs) while pretending to be Bastian from the Neverending Story.

#1. SHARE TOP 5 THINGS YOU DID THAT HELPED YOU GROW & BECOME THE PROFESSIONAL YOU ARE TODAY

Robin:

  • Regular participant and speaker at conferences & local user groups
  • Coaching teams and organizing internal meetups about software development
  • Working with different teams and companies (I’m a freelancer)
  • Ask professionals how they would solve a problem
  • Try to read the whole internet 😉

Andreas:

  • Initiating a conference (SoCraTes)
  • Visiting and speaking at conferences
  • Listening and questioning my own views
  • Working with different teams (during my previous job)
  • Thinking outside the box

 

#2. What challenges will the participants find solutions to during your session at I T.A.K.E Unconference 2016?

Participants will learn about the possible pitfalls and gaps when using mock objects blindly. They will understand that this may lead to decreased safety for refactoring and this weakend trust initiates the need for creating more and more integration tests.
They will see the underlying principles and learn about ways and techniques to escape this trap.

 

3. What else would you like to share with participants

Robin:
I like to talk about different software development approaches. How can we use and maintain software tests from specifications and end-to-end-tests to unit-tests. And I would like to know how other teams share their knowledge and improve the collaboration inside the team.

Andreas:
Don’t be shy. Open your ears and eyes. Listen and ask.
