If a regulator asks how you would move off your current cloud provider tomorrow, "we would figure it out" is no longer an acceptable answer. Most modern cloud deployments are deeply tied to provider-specific services, creating invisible dependencies that make true portability feel out of reach.

Multi-cloud runtime approaches are expensive and complex, requiring duplicated infrastructure and operational teams. What you actually need is standardized portability.

Here is how you can tackle it:

Define your entire application environment using a single configuration file.

Keep your infrastructure definition provider-agnostic, versioned, and auditable right inside your Git repository.
