Cloud-init documentation
########################

``Cloud-init`` is the *industry standard* multi-distribution method for
cross-platform cloud instance initialisation. It is supported across all major
public cloud providers, provisioning systems for private cloud infrastructure,
and bare-metal installations.

During boot, ``cloud-init`` identifies the cloud it is running on and
initialises the system accordingly. Cloud instances will automatically be
provisioned during first boot with networking, storage, SSH keys, packages
and various other system aspects already configured.

``Cloud-init`` provides the necessary glue between launching a cloud instance
and connecting to it so that it works as expected.

For cloud users, ``cloud-init`` provides no-install first-boot configuration
management of a cloud instance. For cloud providers, it provides instance setup
that can be integrated with your cloud.
