During the Codemotion Rome 2019 conference, Mercedes Wyss delivered the talk “Modern Identity Management (in the Era of Serverless and Microservices)”. We asked Mercedes these questions: what is Identity Management and how can we do it effectively? How are Identity Management and Serverless / Microservices related? What benefits have using a platform, against writing your own code and then deliver it to developers? As a CTO, how do you measure the quality of your infrastructure, your software, and your teams?
