Replacing RSA or elliptic-curve cryptography in one application library does not make a cloud-native system quantum-ready. Cryptography is spread across gateways, service meshes, certificates, workload identities, cloud KMS, CI/CD signing, and vendor-managed services. The real job is to discover those dependencies, rank them by risk, move algorithm choices behind policy, roll out hybrid or post-quantum modes progressively, measure production behavior, and retire legacy algorithms with evidence.
