Platform model
Aether is built around a clean split: you own and run your tenant clusters; we run the control plane. Understanding that split makes everything else fall into place.
Tenant clusters
Section titled “Tenant clusters”A tenant cluster is a Kubernetes cluster that belongs to your organization.
It’s where your workloads run. You create as many as you need, on the regions you
choose, and you have full kubectl-level control over what runs inside them:
Deployments, Services, ingress, network policies, persistent volumes, and so on.
The managed control plane
Section titled “The managed control plane”Every cluster has a Kubernetes control plane — the API server and the components that schedule and reconcile your workloads. On Aether, the control plane is fully managed. Aether provisions it, operates it, keeps it healthy, and backs it with a fully managed datastore.
You never:
- Manage, patch, or upgrade the control plane’s machines.
- SSH into control-plane nodes.
- Size, scale, or babysit the control-plane database.
You only ever interact with the control plane through its Kubernetes API — the same way any Kubernetes client does.
Tenant isolation
Section titled “Tenant isolation”Each tenant cluster is isolated from every other tenant. Your clusters get their own private network for workloads and nodes, their own control plane, and their own datastore. One organization’s clusters can’t see or reach another’s.
Who’s responsible for what
Section titled “Who’s responsible for what”| Aether handles | You handle |
|---|---|
| Provisioning and operating the control plane | Your workloads and manifests |
| Control-plane health, datastore, and backups | Your application data and PVCs |
| Installing the Cilium CNI | Your NetworkPolicy rules and ingress |
| Bringing up and tearing down worker nodes | Choosing node-pool sizes and counts |
| Managed load balancers, block storage, registry | Using them from your workloads |
