I gave this talk at the AWS User Group in Cologne in April 2019 (https://www.meetup.com/aws-cologne/events/260502656/).
It is about performance testing with a outlook on implications with Serverless systems. I'll go over some challenges you can expect with such systems and try to outline strategies how to approach this topic in general. In addition I'm taking about a common performance pitfall when using Serverless with Node.js as well.
