title: "Multi-Location Clusters"
linkTitle: "Multi-Location"
description: "Extend Cozystack management clusters across multiple locations using Kilo WireGuard mesh, cloud autoscaling, and local cloud controller manager."
weight: 40
---

This section covers extending a Cozystack management cluster across multiple physical locations
(on-premises + cloud, multi-cloud, etc.) using WireGuard mesh networking.

The setup consists of three components:

- [Networking Mesh]({{% ref "networking-mesh" %}}) -- Kilo WireGuard mesh with Cilium IPIP encapsulation
- [Local CCM]({{% ref "local-ccm" %}}) -- cloud controller manager for node IP detection and lifecycle
- [Cluster Autoscaling]({{% ref "autoscaling" %}}) -- automatic node provisioning in cloud providers

linkTitle: "Autoscaling"
description: "Automatic node scaling for Cozystack management clusters using Kubernetes Cluster Autoscaler."
weight: 20
---

The `cluster-autoscaler` system package enables automatic node scaling for Cozystack management clusters.
It monitors pending pods and automatically provisions or removes cloud nodes based on demand.

Before configuring autoscaling, complete the [Networking Mesh]({{% ref "../networking-mesh" %}})
and [Local CCM]({{% ref "../local-ccm" %}}) setup.

Cozystack provides pre-configured variants for different cloud providers:

- [Hetzner Cloud]({{% ref "hetzner" %}}) -- scale using Hetzner Cloud servers
- [Azure]({{% ref "azure" %}}) -- scale using Azure Virtual Machine Scale Sets

Each variant is deployed as a separate Cozystack Package with provider-specific configuration.
