Software Architect Mirko Ebert

(Doors 18:15 and Presentation at 19:00)

The year is 1949 and the city is Hamburg, Germany. A small catalogue company is founded. 50 years later, with the internet revolutionalising retail shopping, it transforms into an E-Commerce company. Today OTTO employs over 600 employees and has annual sales revenue exceeding €2 billion.

At the Dublin Java User Group's August meetup, we're pleased to welcome OTTO software architect Mirko Ebert to the stage at TechMeetup.Space.


Session 1 – Robustness Testing with Brigade of Monkeys

Mirko Ebert (@mirkoebert)

After some years with a commercial product, OTTO decided to develop their own E-Commerce shop. As one outcome of this early shop, the software design team recognized that non-functional requirements are internal quality factors of the Scala / Clojure / Java based software.

The new version of the robustness test framework Brigade of Monkeys (BoM2) is an example of polyglot programming. It uses, for example BASH, R, Ant, JavaScript, Python. The new version of BoM2 is Open Source and under heavy development.

In Mirko's session, he will show how OTTO tests, and measure loads, performance and robustness of the new shop. Especially, the focus is on robustness testing.
