Multi-Region Architecture¶

Key Considerations¶

Data Residency¶

Replication Strategies¶

# Configure GRS for Data Lake
az storage account create \
    --name datalakeprimary \
    --resource-group rg-analytics \
    --location eastus \
    --sku Standard_RAGRS \
    --kind StorageV2 \
    --hierarchical-namespace true

# Enable failover
az storage account failover \
    --name datalakeprimary \
    --resource-group rg-analytics \
    --failover-type planned

Disaster Recovery¶

Implementation¶

Cross-Region Query¶

-- Query across regions using linked servers
SELECT
    p.Region,
    p.ProductCategory,
    SUM(p.Revenue) AS TotalRevenue
FROM PrimaryRegion.Sales p
UNION ALL
SELECT
    s.Region,
    s.ProductCategory,
    SUM(s.Revenue)
FROM SecondaryRegion.Sales s
GROUP BY Region, ProductCategory;

Global Data Catalog¶

# Register multi-region assets in Purview
from azure.purview.catalog import PurviewCatalogClient

def register_global_asset(asset_name, regions):
    """Register asset across multiple regions."""

    for region in regions:
        entity = {
            "typeName": "azure_datalake_gen2_path",
            "attributes": {
                "name": asset_name,
                "qualifiedName": f"adls://{region}-storage/{asset_name}",
                "region": region
            }
        }
        client.entity.create_or_update({"entity": entity})
