AKI, or *Amazon Kernel Image*, are a specific type of image. It represents the Xen guest para-virtualized kernel, as used by an AMI. Certain AKIs are allowed to boot customized operating systems, e.g. those that are still not officially supported by Amazon. Thanks to [PyGrub](http://wiki.xensource.com/xenwiki/PyGrub), it can boot a kernel that resides inside an AMI's snapshot. |

Well, you got a NetBSD instance that is in almost every part similar to what a NetBSD domU can be. You can use this domU to host Internet services, run a database, extend your build farm, or use it as a sandbox. The AMI being built around snapshots, you can play and break your instance in every way you want; just restart one anew if you need to. Don't forget that Amazon will charge acccordingly :) |

Remember, you can query information regarding your AWS account through [[!template id=pkg category=misc name=ec2-api-tools]] package. It is quite easy to use these tools for scripting; for a more elaborate, graphical interface, use the [Amazon Management Console](https://console.aws.amazon.com/ec2/home). |
