Platform Engineering's Next Test Is Environment Consistency

Fast IaC provisioning doesn't guarantee test environments behave like production; data, traffic and drift matter.
Infrastructure as code makes environments easy to provision but not to make representative, the article argues, citing anonymized staging data that hid tenant-specific performance bottlenecks and a Java runtime update applied to staging but never to production.
Platform teams should treat data preparation and workload profiles as part of environment engineering and manage configuration like application code, with versioning, reviews, automated tests and monitoring.
They should measure consistency by outcomes such as deployment failures, rollbacks and production defects rather than by matching config files.
