Twelve control objectives that keep complexity manageable..

Multi-cloud becomes fragile when identity, network, and governance are inconsistent. Establish a shared baseline before scaling workloads.

1. Identity & Access: SSO, MFA, just-in-time access, role-based least privilege.
2. Landing Zones: Standardized accounts/subscriptions, naming, tagging, and guardrails.
3. Network: Hub-and-spoke patterns, private endpoints, encrypted transit, egress control.
4. Secrets & Keys: Centralized KMS/HSM and rotation policies.
5. Data Protection: Classification, residency maps, backup/DR with tested RTO/RPO.
6. Workload Security: Baseline images, image signing, runtime policies.
7. Monitoring & SIEM: Centralize logs/metrics/traces, alert on SLO and security events.
8. Change Control: GitOps or pipeline-gated IaC; drift detection.
9. Compliance: Map controls to ISO/NIST/SOC 2; automated evidence collection.
10. Cost Governance: Budgets, anomaly alerts, chargeback; FinOps operating model.
11. Resilience: Multi-AZ by default; chaos drills and incident runbooks.
12. Vendor Exit Plan: Data export paths and portable architectures.
