If a deployed app error occurs but is not observed does it happen? We've all been here before, apps that have been deployed but not optimized not only affect performance but can also cost you resources and money. If a log is generated on a stack and is not observed, does it happen? For a dev that final commit and code test pass means the end of a long project, or does it? That code may run, and those tests may pass, however, those application logs not being viewed may present an issue for that amazing code. Building applications to scale is critical, as devs, we build our applications to help our end users have a great app experience and not cost in infrastructure resources or slow and unresponsive applications. Optimizing and debugging the code base to work on the nominated infrastructure is the final stage in application deployment and in this talk, we are going to look at some ways to debug and trace a containerized Python application.
