 EC2 uses different types of credentials. In addition to your login and password, you need an access key, a X.509 certificate (with its private key), and a pair of RSA keys, for remote SSH access.  EC2 uses different types of credentials.

 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.  AKI, or *Amazon Kernel Image*, are a specific type of image.

 (For the future) Once NetBSD has decent support for Amazon EC2, we will publish the AMI identifiers so you can quickly boot up in a NetBSD environment without going through all the steps given below.

 ## Upload your OS  # Uploading NetBSD to EC2
   
 We must now upload our NetBSD system to EC2. For that, we will have to create a minimalist EC2 instance, to which we will copy our files to construct our snapshots. For that, we will use an Amazon Linux AMI instance.  We must now upload our NetBSD system to EC2.

To have a list of EC2 regions, you can use the command **ec2-describe-regions**, and **ec2-describe-availability-zones** for availability zones.  The examples listed here assume that the instances run in **US East**, within the **c** zone (e.g. **us-east-1c**).

 Creating an instance straightforward. Amazon provides [different types of instances](http://aws.amazon.com/ec2/pricing/), with varying levels of billing and reliability. We will use a [*micro* instance](http://aws.amazon.com/ec2/faqs/#How_much_compute_power_do_Micro_instances_provide); its pricing is almost free.  Creating an instance straightforward.
