Regions & data residency¶
China is a separate cloud
Azure China (21Vianet) is not connected to global Azure. Identities, endpoints and data are isolated. Never assume a global-cloud tool can reach China resources, and never move China data cross-border.
Region matrix¶
| Region | Cloud | Residency rule | Notes |
|---|---|---|---|
| EMEA (West Europe) | Global Azure | EU data stays in EU | Primary landing zone |
| Brazil (Brazil South) | Global Azure | LGPD applies | Latency-sensitive to EU |
| China (China North 3) | Azure China 21Vianet | In-region only | Separate identity + endpoints |
| On-prem | Datacenter (vCenter) | Internal only | Egress to Azure DevOps only |
Documentation implications¶
- China/on-prem sensitive content is classified and kept in-region.
- This global wiki holds non-sensitive summaries + links, never in-region confidential detail.
- Provisioning playbooks branch on
region/data_residencyvariables — see the Provisioning runbook.
