Three environments, one product
Your team works on several features at once. In the cluster “Development” it experiments on two Compute nodes, fast and affordable. In the cluster “Staging” it checks every version on three nodes under realistic conditions. And “Production” carries your customers on four nodes. All three are the same kind of cluster with an HA control plane, private networking, scaling groups, and one-click upgrades. So staging behaves like production, just smaller.
