Post-Quantum TLS for Cloud APIs and Microservices

This story was originally published on HackerNoon at: https://hackernoon.com/post-quantum-tls-for-cloud-apis-and-microservices. Learn how to migrate cloud TLS to X25519MLKEM768 by treating every TLS termination as a separate boundary, with telemetry, fallback controls, and rollout gates.

Hybrid post-quantum TLS is not a single application switch—every gateway, proxy, load balancer, and service connection must be migrated and verified independently. X25519MLKEM768 adds manageable CPU cost but substantially increases handshake size, making connection reuse, compatibility testing, telemetry, explicit policies, and reversible rollout gates essential.
