Overview

Each instance may provision one or more additional unmanaged and managed network interfaces. This interface is bound to a private network segment shared only with your other instances.

Terminology

  • Managed Private Network
    Managed Private Networks allow you to create Private Networks with a DHCP server managed by Exoscale.\
  • Manual Private Network
    A Manual Private Networks allow you to create your Private Network with a static IP configuration on each instance.

Features

The Private Network is a classic layer 2 segment: it is as if your instances were attached to a dedicated switch. This means:

  • You can use any ethernet-compatible protocol (IPv4, IPv6, NetBIOS).
  • Security group rules do not apply to traffic inside private networks.
  • Multicast and broadcast are authorized.
  • Only your instances are attached to the segment.
  • No encryption is performed, but your packets do not leave our datacenter.
  • Private Networks can be managed.
  • Private Networks do not span across several zones.

However, there is a small difference: unknown MAC addresses cannot be used. Do not create a bridge including the private interface.

By default, there is no DHCP listening on your Private Network. If you want a DHCP server attached to your Private Network, you should create a managed Private Network. Managed Private Networks allow you to create Private Networks with a DHCP server managed by Exoscale in order to automatically configure the IP addresses of your Private Network interfaces. You can also assign specific IP addresses to Private Network interfaces.

NOTE
In order to use managed Private Networks, install Cloud Init version 19.3 or later on your instance to use the Exoscale datasource. You can learn more about Cloud Init on the Cloud Init documentation page.
