End-to-end load testing at scale

Oliwia Zaremba, Software Engineer at Zalando SE

Zalando served over 4,200 orders per minute at the peak of Black Friday 2018 campaign. In the world of microservices, Kubernetes, autoscaling and ubiquitous monitoring, load testing still played a crucial role to ensure the readiness of all the systems without overprovisioning and wasting money. I will share the challenges we met during our journey and the lessons learned from the process of simulating real users’ behavior on Zalando website at a large scale.

Nachum Dimer, Co-founder and CEO

Test automation has been around for almost two decades yet for many years the market was questioning its efficiency and ROI. However, since Selenium framework has been released, test automation has been seeing a renaissance.
