Implementing ALM with Databricks Asset Bundles
You have an Azure Databricks solution that was developed by multiple engineers and deployed to development, test, and production environments. You need to implement an application lifecycle management (ALM) process that meets the following requirements: Deploys and provides source control for Databricks notebooks, workflows, and jobs in a consistent and repeatable way Parameterizes the target deployment environment What should you include in the solution?
Community Insight
The question tests knowledge of modern DevOps practices in Databricks, specifically identifying that Asset Bundles are the correct tool for Git-integrated ALM, while older methods like workspace export/import or manual promotion lack automation.
Databricks Asset Bundles provide the standard mechanism for managing application lifecycle management in Azure Databricks by enabling Git-based source control and repeatable deployments. This solution addresses requirements for environment parameterization and consistent resource deployment across multiple environments.
Candidates often select 'export and import of Databricks workspaces' because it is a legacy method for moving resources, but it does not support Git source control or automated parameterized deployments required by the scenario.

Expert Analysis
Why the Answer Is Correct
Declarative Automation Bundles (now known as Databricks Asset Bundles) are the recommended approach for Application Lifecycle Management (ALM) in Azure Databricks. They allow you to define your infrastructure and code as code, storing it in Git for version control. The bundles support target configurations that enable parameterization of deployment environments (development, test, production), ensuring consistent and repeatable deployments of notebooks, jobs, and workflows.Why the Other Options Are Wrong
Option A (Export/Import) is a manual process that does not integrate with Git for source control and lacks the ability to automate parameterized deployments. Option B (Terraform provider) is excellent for provisioning the underlying cloud infrastructure (like clusters or VPCs) but is not the primary tool for managing the deployment of Databricks-specific artifacts like notebooks and workflows within the ALM context described. Option C (Git folders and manual promotion) introduces a manual step ('manual promotion') which contradicts the requirement for a consistent and repeatable automated process.Community Comment Notes
Community consensus strongly supports Option D. As one user noted, "Declarative Automation Bundles in Git... Provides source control in Git. Supports consistent, repeatable deployments across dev/test/prod." This aligns with Databricks documentation emphasizing Asset Bundles for CI/CD pipelines.Exam Strategy
When asked about ALM, source control, and Git integration in Databricks, always look for 'Asset Bundles' or 'Bundles' as the answer. Avoid options involving manual processes or tools designed strictly for infrastructure provisioning rather than application code deployment.
Frequently Asked Questions
Why not use Terraform for deploying notebooks?
Terraform manages cloud infrastructure resources. While it can deploy some Databricks objects, Asset Bundles are the native, optimized tool for managing notebooks, jobs, and workflows via Git.
What is the benefit of parameterizing targets?
It allows the same bundle definition to be deployed to different environments (dev, prod) with specific variables (like cluster sizes or endpoints) without changing the core code.
