概要
This skill provides a comprehensive decision framework and implementation patterns for building applications that span multiple cloud providers or maintain cloud-agnosticism. It offers side-by-side service comparisons across AWS, Azure, and GCP for compute, storage, and database layers, helping developers select optimal services while avoiding vendor lock-in. Whether you are implementing disaster recovery strategies, migrating workloads, or optimizing costs through cross-provider distribution, this skill streamlines the complex process of cross-cloud infrastructure planning and deployment using proven architectural patterns.
