That's why assessing the associated risk at any time is crucial. Engineering teams need to consider whether they can roll out new features or invest in stability - a balance between reliability and engineering velocity is key. In this session, we will uncover significant risks in a microservice architecture by running a few tests during a demo on stage. You will take home valuable tips you can implement on your next workday to build reliable systems under unpredictable conditions. If you need to roll out new features to your customers in a reliable way at any time, join this talk.
