The author shares their experience of migrating a Kubernetes cluster from DigitalOcean to Hetzner, highlighting significant cost savings of over 75% and increased compute capacity. The migration involved setting up a self-managed Kubernetes control plane, using Terraform and Puppet for node management, and overcoming challenges related to node roles, networking, and storage. Hetzner's affordable pricing and useful open-source tools such as load balancer controllers and container storage providers are emphasized, despite some limitations in customer service, IP quality, and feature parity.
