Cloud design principles: loose coupling, designing for failure, automation and operations as code

Beyond the six Well-Architected pillars, AWS teaches a handful of general design principles for cloud architectures. They explain why cloud designs look different from traditional data center designs: in the cloud, resources are cheap to create and destroy, failures are expected, and almost everything can be controlled through an API. The Cloud Practitioner exam checks that you recognize these principles and can pick the architecture that follows them.
