Azure Databricks DR/BCP Deployment

Goal of this repo is to develop Databricks DR automation based on best practice suggested by various DB articles.

---

DevOps Automation workflow for Multi-region DR

This Terraform configuration deploys:

• A Databricks workspace (Premium tier)
• A VNet with:
  • Public and private subnets
  • Subnet delegation for Databricks
  • NSG (Network Security Group) attachments
• VNet injection for secure Databricks deployment
• Support for Active/Passive DR setup across regions

🛠️ Requirements

• Terraform >= 1.3
• Azure CLI (az login)
• Sufficient Azure permissions to create resources

az account set --subscription "<your-subscription-name-or-id>"

Create resource group

az group create \
  --name databricks-demo \
  --location eastus

az storage account create \
  --name bcrterraformstatefiles \
  --resource-group databricks-demo \
  --location eastus \
  --sku Standard_LRS \
  --kind StorageV2 \
  --allow-blob-public-access false


az storage account keys list \
  --account-name bcrterraformstatefiles \
  --resource-group databricks-demo \
  --query "[0].value" \
  -o tsv

az storage container create \
  --name tfstate \
  --account-name bcrterraformstatefiles \
  --account-key <YOUR_STORAGE_ACCOUNT_KEY>

🚀 How to Deploy the Infrastructure

# Step into the environment folder
cd infra/prod/eastus

# Initialize the Terraform project
terraform init

# Preview what will be created
terraform plan -var-file="terraform.tfvars"

# Apply the infrastructure
terraform apply -var-file="terraform.tfvars"

** Wait for 5 minutes before login to the workspace **

How to Deploy the Jobs/Code

export DATABRICKS_HOST="https://<Databricks-instance-id>.cloud.databricks.com"
export DATABRICKS_TOKEN="<YOUR-PAT>"

cd /apps/dev
terraform init
terraform plan -var-file="terraform.tfvars"
terraform apply --auto-approve -var-file="terraform.tfvars"

🧹 To Destroy

terraform destroy -var-file="terraform.tfvars"

✅ Outputs

After deployment, you'll get:

• databricks_host — URL to access your Databricks workspace

📝 Notes

• Adjust the terraform.tfvars to match region and resource group for each deployment.
• Use additional folders like westus for DR/secondary regions.
