In this episode Zalando describes their recent move to creating and releasing a number of their internal projects as open source and how that has benefited their business. We also discussed how they are leveraging Python and a couple of the libraries that they have published.

- Can you start by telling us a bit about what Zalando does and some of the technologies that you use? – Tobias
- What role does Python play in your environment? – Tobias
- Is the use of Python for a particular project governed by any particular operational guidelines or is it largely a matter of developer choice? – Tobias
- Given that you have such a variety of platforms to support, how do you architect your systems to keep them easy to maintain and reason about? – Tobias
- One of the projects that you have open sourced is Connexion. Can you explain a bit about what that is and what it is used for at Zalando? – Tobias
- What made you choose to standardize on Swagger/OpenAPI vs RAML or some of the other API standards? – Tobias
- Did Connexion start its life as open source or was it extracted from another project? – Tobias
- ExpAn is another one of your projects that is written in Python. What do you use that for? – Tobias
- Can you describe the internal implementation of ExpAn and what it takes to get it set up? – Tobias
- Given the potential complexity of and the need for statistical significance in the data for proper A/B testing, how did you design ExpAn to satisfy those requirements? – Tobias
- Given the laws in Germany around digital privacy, were there any special considerations that needed to be made in the collection strategy for the data that gets used in ExpAn? – Tobias
