Cloud-init is the industry standard multi-distribution method for cross-platform cloud instance initialization.
During boot, cloud-init identifies the cloud it is running on and initializes 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.
