In this talk, I’ll show how I slashed costs at https://ew.academy by replacing multiple SaaS services with a self-managed Kubernetes infrastructure built on open-source tools. You’ll see how I evaluated alternatives, deployed them at scale, and overcame daily challenges—alongside real savings data. Attendees will gain strategies to reduce expenses, avoid vendor lock-in, and regain control of their systems.
