The allure of multi-cloud strategies is undeniable, promising cost savings, regulatory compliance, and freedom from vendor lock-in. However, the reality of adding a second cloud provider to an existing AWS setup is far messier, with hidden costs in operational complexity often outweighing perceived benefits. Integrating disparate IAM systems, networking setups, and monitoring tools is not merely a matter of plugging in APIs; it requires reconciling conflicting policies, quotas, and billing models, often necessitating custom tooling or manual intervention.
For instance, AWS's IAM roles do not map cleanly to Azure's RBAC, potentially leading to security gaps if not meticulously aligned. This friction can derail projects when teams underestimate the effort required.
