Over the past two years we have been on an exciting journey building a new state-of-the-art web portal for SAP. In this second session we would like to focus on what we did from a performance & backend perspective to build and operate such a portal. We will go into detail on UI5 performance optimizations we did, leveraging our state-of-the-art local development workflow and open source UI5 Node.js tooling, bringing our bootstrap down to a sub-second loading time of our application. Also we did built a cloud-native development backend using open source in order to facilitate our development.
