Answer: Manually restoring the previous version of the notebooks from a backup copy stored in Azure Blob Storage
The most efficient and quickest way to rollback the deployment to a stable version is by manually restoring the previous version of the notebooks from a backup copy stored in Azure Blob Storage. This approach allows for a revert back to a known stable state without the complexity of automation or monitoring solutions. Accessing and restoring the notebooks from Azure Blob Storage ensures immediate action can be taken to rectify critical issues affecting data quality, bypassing the need for additional setup or configuration. While options like Azure DevOps release pipelines or Azure Log Analytics offer future prevention and robust deployment strategies, the immediate need for a rollback is best served by a manual restoration from backup.
