    We can imagine that at a regular company your colleagues might become very nervous when you worsen the frontend performance by more than a second on the onload, just before the peak season. In this story we’d like to share our journey from experiencing a setback in performance that was caused by us innovating, to the point where we became the retailer with the second fastest frontend response times (Twinkle and Computest benchmark study) in the Netherlands.

    Peter Paul van de Beek, Peter Brouwers, on 26-09-2019
    Category: Podcast Tags: Architecture Scalability cloud Podcast redesign

This time we dive into “Redesign for the cloud – horizontal scaling”. In an earlier episode we discussed how we moved our Big Data to the Cloud, in the Cloud as an enabler to becoming more data-driven.

    Category: Podcast Tags: Web scale Scalability Agile Scrum Podcast Product teams Agile@scale Flight level Business Agility

    Agile at Scale. Ever since we started our journey into Agile and scrum, we have been wondering whether we were on the right path for business and IT agility. Way back when we were with 7 scrum teams scaling wasn’t the most important issue. With our growth came challenges for scaling our agile way of working. We have been on a few plateaus where we were searching for the next step, as have been other companies on the same venture. Today we talk about some of the things we learned…
