Developer Experience on Kubernetes

As a developer, working with Kubernetes too often leads to too much cognitive load, inefficient inner development loop, and friction in the path to production. This session is structured as a series of iterations on the developer experience to improve those three aspects and boost productivity, while following an approach based on open-source technologies.

Developer Experience “…developer experience could be defined as a means for capturing how developers think and feel about their activities within their working environments, with the assumption that an improvement of the developer experience has positive impacts on characteristics such as sustained team and project performance.” (F.
