  "account": "A new approach to migration prioritizes testing the destination environment before moving workloads. The author argues that environment portability should focus on proof rather than discovery. The key is defining an Environment-as-a-Contract—a list of external capabilities and relationships required for the workload to operate. By testing these requirements in the target environment before migration, potential issues can be identified and resolved early on. The author suggests leveraging AI to automate the process of generating requirements by analyzing existing repositories, code, and documentation. While not all requirements need automated tests, the goal is to move valuable uncertainty to an earlier, less costly stage in the migration process. This approach differs from traditional Infrastructure-as-Code (IaC) and smoke testing, which focus on building resources and verifying basic functionality after deployment. Portability, in this context, means identifying environmental requirements and proving another environment can satisfy them, rather than assuming an application has no dependencies.",
  "summary": "An emerging pattern for making workload portability less about discovery and more about proof. I've watched migrations go wrong in remarkably predictable ways. The application itself is usually not the problem. The software builds. The infrastructure gets provisioned. The deployment succeeds. Then something doesn't work. A service can't authenticate because a trust relationship wasn't recreated.…",
