cloud-init Description
Cloud images are operating system templates. Every instance starts as an identical copy of every other instance. It is the user data that gives each cloud instance its personality. Cloud-init is the tool that automatically applies that user data to your instances. You can include datasource and module references. There are many examples. Cloud-init was originally developed for Ubuntu but is now available on most major Linux and FreeBSD operating system platforms. Cloud-init automatically handles differences between cloud image providers -- for example, official Ubuntu cloud images are identical across both public and private clouds.
