Abstract
Modern web apps face new challenges when it comes to availability and performance. It is mandatory to gain operational insights in real-time and get early warnings to prevent outages. In a live coding session we kickstart a web app and show how we can easily include opencensus metrics and tracing. Building modern web applications is no hard job anymore, thanks to frameworks which solve a lot of common problems for us. One of these frameworks is Flamingo and we will use it in this live coding session to build a small web application from scratch. In a couple of minutes and only a few lines of code we will already get a running application with a simple controller and a route to it. In order to bring our application into production with a clear conscience, we need operational insights in real-time. We will therefore implement a healthcheck, provide opencencus metrics and tracing. The Flamingo framework provides a set of modules for operational readiness which we use to make our application production-ready.
