The document discusses why startups need automated infrastructures. It explains that an automated infrastructure allows basic services to operate largely without human intervention, saving time and increasing efficiency, scalability, flexibility and reducing costs. It provides an example of automating the launch of a fictional startup called MonkeyNews using tools like Puppet, EC2, iClassify and Capistrano. This allows the infrastructure to dynamically scale and issues to be resolved quickly through automation.
