+# Azure SQL
+
+Deploy managed databases on Azure.
+
+## Create SQL Database
+
+```bash
+# Create server
+az sql server create \
+  --name myserver \
+  --resource-group mygroup \
+  --admin-user sqladmin \
+  --admin-password SecureP@ss123
+
+# Create database
+az sql db create \
+  --resource-group mygroup \
+  --server myserver \
+  --name mydb \
+  --service-objective S1
+```
+
+## Firewall Rules
+
+```bash
+az sql server firewall-rule create \
+  --resource-group mygroup \
+  --server myserver \
+  --name AllowAzure \
+  --start-ip-address 0.0.0.0 \
+  --end-ip-address 0.0.0.0
+```
+
+## Cosmos DB
+
+```bash
+az cosmosdb create \
+  --name mycosmosdb \
+  --resource-group mygroup \
+  --default-consistency-level Session
+```
+
+## Best Practices
+
+- Enable transparent data encryption
+- Use Azure AD authentication
+- Implement geo-replication
+- Configure automated backups
+- Use private endpoints
