Why clouds should be more like operating systems
Let's say you are running multiple different Amazon Machine Images (AMIs), which contain your applications, libraries, data and configuration settings on Amazon's Elastic Compute Cloud (EC2), and you are using Amazon's S3 for storage. Don't think running everything in the cloud will abstract away potential management problems. You'll still have a system administration headache until you script something or update your AMIs with your new software and application code.
