At trivago we operate on petabytes of data. In live-traffic applications that are related to the bidding business cases we use our in-house in-memory key-value storage-service written in Java to keep data as close to calculation logic as possible.
Have you ever wondered about how to create components that not only change their appearance according to the viewport’s width but instead also transform according to their parent element’s sizing? This might be the case when you have a card component that has the classical vertical layout on mobile:
At trivago, we run webservices with complex backends in different regions around the globe 24/7. Our system is being iterated and developed on a daily basis.

In the middle of summer 2021, we hosted one of our favourite annual events of the year - trivago Tech Week! This year’s tech week had a new, hybrid format, featuring a wide variety of talks and exchange forums, hosted both by internal talents and external speakers. To make things even more engaging, the week included virtual opportunities for talents to gather and converse across departments, a gaming tournament and a highly anticipated live-music concert to tie everything together!
While engineering, we fix bugs, create new systems, build workflows and establish processes. Our job is to change things. Changing things can involve mistakes that ultimately lead to the failure of a particular system. To learn from these failures, a retrospective is helpful to get to the root of this problem. In the tech industry, a Blameless PostMortem is the right tool for this job.
When was the last time you booked accommodation without checking its photos? Most probably never! Because having imagery information makes our decision-making process much easier and faster. However, picking up the best possible images of a hotel to show to the user is an interesting problem to solve, because it can be a naive random selection or a sophisticated machine learning model to know what the user truly wants at that moment.
When operating applications in Kubernetes, proper lifecycle management is crucial to enable Kubernetes to manage applications correctly throughout their different phases: startup, runtime and shutdown. Improper or incomplete lifecycle management can lead to incidents with unforeseen and difficult to debug application behavior, such as random CrashLoopBackOffs, broken/zombie services not being restarted or even entire services not becoming healthy after a scheduled restart.
