The well-architected automation framework
summary
Argues that flaky tests are solved but where tests run causes the real risk, citing Target’s ~40 million card breach and GDPR fines starting at €20,000 up to 20% turnover. Applies AWS Well Architected Framework to test infrastructure across five pillars: Operational Excellence, Security, Reliability, Performance Efficiency, Cost Optimization. Recommends Terraform + config management (Ansible/Puppet), CloudTrail/CloudWatch/Lambda, chaos engineering, autoscaling and tagging, and a hard rule: do not copy production data.
