Multi-cloud standardisation: what to enforce and what to leave flexible
Three questions. Seven control areas. A clear recommendation per area based on your provider count, team size, and regulatory context.

Your Setup
Three questions to calibrate the recommendations to your situation.
What You Need to Get Right
Select all that apply. You will rate each one in the next step.
Where You Are Today
For each selected area, how consistent is your current state across providers?
Your Recommendations
Single provider. Define roles and federation once. Any inconsistency is entirely self-inflicted.
What good looks like: A central IdP federated to all active providers. Every human access entry has a named owner and a review date. No long-lived service account keys. See: RBAC patterns for production cloud environments. RBAC.
One provider. Standardise your VPC layout, subnet scheme, and egress path. There is no complexity argument for divergence.
What good looks like: A network diagram that matches what is deployed. Egress through a controlled path. Private endpoints for managed services in production. See: Network topology in multi-cloud estates. Network topology.
No IaC yet, or single provider. Start with a standard module structure. Diverging before you have a baseline creates debt from day one.
What good looks like: Zero production infrastructure provisioned outside version control. New environments reproducible from code. Remote state with locking on every provider. See: Terraform module patterns for multi-environment cloud estates. Terraform modules.
One provider. No reason to diverge. Pick a log destination and enforce it.
What good looks like: Every production service has a log destination and 90-day minimum retention. Management audit logs immutably retained and inaccessible to workload accounts.
Single provider. Enforce tagging on every resource. Use provider-native cost allocation. No abstraction needed.
What good looks like: Every resource tagged with team and environment. Daily or weekly cost report by team. Budget alerts fire before overspend, not after the invoice.
One provider or large teams. Standardise your CIS benchmark controls, vulnerability scanning, and secret hygiene.
What good looks like: A written baseline that is tested automatically in CI. CIS benchmark enabled on all providers. No long-lived credentials in code, images, or CI secrets. See: Golden image architecture for production Linux baselines. Golden images.
One provider. No divergence is possible. Standardise your runbooks now.
What good looks like: Every production service has a runbook written by someone other than the primary engineer. All alerts route to a single on-call platform.
