Kubernetes without nodes
Fly Kubernetes allows for a node-less Kubernetes setup using a combination of a trimmed-down Kubernetes version called k3s for the control plane and Virtual kuet, which emulates traditional kubelet behavior. Instead of worker nodes, Fly uses virtual nodes and its own machines API to manage pods and orchestration. This decentralized approach offloads scheduling decisions to Fly’s own orchestrator, leveraging high availability and self-managed physical machines.

Do you REALLY need Kubernetes?
Kubernetes is not always necessary for startups, and they often reach for it prematurely due to misconceptions. Orchestration, fundamentally about managing multiple containers across physical machines, can be achieved without Kubernetes. Kubernetes offers benefits like a common, cloud-agnostic language and declarative management, making sense for complex, large-scale applications. However, simpler alternatives can handle orchestration tasks, and startups should carefully consider their real needs before adopting Kubernetes.
