Zero-Trust Cloud Infrastructure: A Practical Production Guide

Traditional perimeter-based security is no longer adequate for modern multi-cloud workloads. Zero-Trust mandates continuous authentication and verification for every service-to-service transaction. ### Core Tenets of Zero-Trust 1. **Never Trust, Always Verify**: Every API request must carry a cryptographically signed identity token. 2. **Mutual TLS Everywhere**: Encrypting inter-pod network communication using lightweight service meshes. 3. **Ephemeral Credentials**: Rotating database and cloud credentials dynamically every 60 minutes using HashiCorp Vault. By incorporating these practices into our Terraform provisioning, security audits become an automated, continuous process.
