For instance, among the greatest benefits of employed in the cloud is that you could instantly scale your hardware to complement usage. AWS performs this with Launch Configurations and Auto Scaling Groups, a effective feature that's a discomfort to apply: getting auto-scaling groups setup properly involves a variety of CLI tools or calling into APIs.

Another painful AWS feature is SimpleDB, which is required to run another Netflix Free Tool, Chaos Monkey (the focus of some other blog entry). Establishing a Simple DB through the AWS CLI tools requires some tricky scripting and a little bit of luck. With Asgard, you just need to punch within the name striking create.
