Getting Started with Amazon's EC2 Cloud

Yesterday I did a quick review of the various cloud offerings from Amazon. Previous to that I had done a review of using S3, the Amazon storage service, with Mac OS X, primarily through the lens of using S3 as a destination for Final Cut Server archives. Today I’m going to go ahead and look at using EC2 from Mac OS X. To get started, first download the EC2 tools from Amazon. Next, log into Amazon Web Services. If you don’t yet have a login you will obviously need to create one to proceed. Additionally, if you don’t yet have a private key you’ll need one of those too – in that case there will be a big green box to create it when you first log in. When the keys are created you can double-click on the x.509 certificate file to install it into Keychain. This key is a private key so make sure not to give it out. You can return to this screen later if you need to. Next, go to the AWS Management Console. Because I don’t personally find the site terribly user friendly I like to keep the Management Console bookmarked. Once you have the Management Console open, click on Instances and then click on Launch Instance. You will then be greeted by a list of prebuilt virtual machines that you can use. Amazon has built Fedora and Windows for you, which will be listed under the QuickStart tab of the Launch Instances screen; however, you can also click on Community AMIs in order to use one that has been built and made available by others within the EC2 community. These include Debian, Ubuntu and CentOS (amongst others). Once you have picked your poison, click on Select and you will then be prompted to create a key pair specifically for the instance. The reason for this is that you might have instances that you’ld like to distribute information for to people you wouldn’t want to access all of your images globally to your account. You can skip this step or enter a name for the keypair and click on Create. Now click on Continue and you’ll be prompted to create a security group. A security group controls the ports that are opened to/from your virtual machine. For Windows you’ll pretty much always want RDC (3389) open (pretty much) and for *nix, typically SSH. Amazon tries to make this easy and so pre-fills the form with common ports based on your use. Think of a security group like an Access Control List on a Cisco. You can resuse them across various instances. Next, click Continue. Next, you’ll be asked to provide a name for the VM (aka AMI), a number of instances of the VM and whether the AMI is to be a smaller, standard item or whether it will be hit with high CPU utilization. You’ll also be able to select the security group to apply to the host based on the previous information. The name will be automatically filled in based on the template you chose to use, so you can actually click on the Change button if you’d like to supply a new name. Next, click Launch and the AMI will start to fire up, becoming an instance. Windows AMIs will take a little longer in my experience than Linux AMIs. While the instance is booting, it is worth mentioning that at this point you’ll notice the option to launch/create volumes and what Amazon calls Elastic IPs. Amazon doesn’t provide an IP for free, as you may have noticed when you accepted their terms of service. Therefore, if you are going to create an instance that will have static access over the WAN using a static IP, you will need to go ahead and assign an elastic IP to it. Unless that is, you can communicate with the instance even if it has a dynamic IP (there are a ton of ways to do this). The volumes option allows you to build storage that is independent of the instance. This can be used to mount on multiple instances (although I haven’t found a way to do so concurrently) or to simply have storage independent of the instance so that you can easily move data. Now click on Instances. Here, you’ll note that your newly created instance is listed. Click on it and then click on More Actions and select Get Password (where OS is the OS you chose to setup). Here, you’ll receive an option to decrypt the password using the Private Key. You can cat the .pem file that was downloaded when you setup the key and copy/paste the entire contents into the field. Once the field has been populated, click on the Decrypt button and you will see the Admin/root password for your new virtual host. Next, click on Connect and you’ll find instructions to connect to your new instance (for Windows it will be a dynamic DNS entry to use RDC with). You can now login. Once you have connected it is as though you are in a typical VM environment. Next, you’ll want to take a look at the options for Bundle Tasks (if you’re using Windows), which allows you to duplicate an AMI into multiple instances. You’ll also want to look at Volumes, as mentioned previously and Snapshots, which can be used to back up the Volumes. Overall, we were able to create a new instance of Fedora, Windows or Ubuntu (even those tuned to be Active Directory domain controllers, LAMP hosts or SQL), faster than if we installed it from scratch and without using any resources outside of Amazon to do so. Later, we’ll look at doing all of this from the command line. And don’t forget to stop your instance so that you don’t get billed for all that time that you’re not using it!
