This is a decision framework for building applications that span AWS, Azure, and GCP. It gives you service equivalency tables (EC2 vs Virtual Machines vs Compute Engine), four core multi-cloud patterns like best-of-breed and geographic distribution, and a phased migration strategy. The cloud-agnostic architecture section pushes you toward Kubernetes, PostgreSQL, and S3-compatible storage as abstraction layers. Honestly, the real value is in the service comparison tables and cost optimization strategies. Most teams end up here after getting burned by vendor lock-in or needing DR in a second cloud. The skill assumes you're working with Terraform and references additional files for deeper pattern documentation.
