 # Introduction  # Introduction
   
 This tutorial aims at showing how you can build, setup, upload and launch NetBSD under the [Amazon EC2](http://aws.amazon.com/ec2/) service.  This tutorial aims at showing how you can build, setup, upload and launch NetBSD under the [Amazon EC2](http://aws.amazon.com/ec2/) service. We will first give some brief explanations on how you can obtain an AWS account, and what you will need to run NetBSD under EC2. Then, at your convenience, you will be able to start with pre-made images, or roll-out your own.

 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.

 We pick the one with the correct architecture (x86_64). **hd00** are for EBS backed images, while **hd0** are for S3 backed ones. Chose **hd00** AKIs. In our case, its ID is **aki-4e7d9527**.  Pick the one with the correct architecture (x86_64 here). **hd0** are for AMIs where the snapshot contains no partition (where the volume is itself the whole partition), while **hd00** are for snapshots partitioned in a classical way (via MBR). Choose **hd0** AKIs. In this case, that will be **aki-427d952b**.

   Done!
   
 ## And now?  ## And now?
   
   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).
