Kubernetes is often the default choice for running applications in production, even when its complexity does not match the team's actual needs. Many teams adopt it to solve problems that could be addressed with simpler approaches.

In this presentation, we will revisit what “production-ready” really means and show how reliability, scalability, security, and observability can be achieved without Kubernetes. Drawing on concrete experience operating a PaaS like Scalingo, we will explore how platform-level abstractions can reduce operational overhead while providing production guarantees.
