Example: if the impact is classified as “Very High”, the implications of not adopting the best practice can have a significant impact on your deployment. Using the Impact factor, you can weigh the recommendation against other competing choices. We've also classified each recommendation according to its likely impact on solution's quality attributes. Our recommendations should apply to a typical Fortune 500 enterprise with at least intermediate level of Azure and Databricks knowledge. Since the Azure Databricks product goes through fast iteration cycles, we have avoided recommendations based on roadmap or Private Preview features. The audience of this guide are system architects, field engineers, and development teams of customers, Microsoft, and Databricks. We follow a logical path of planning the infrastructure, provisioning the workspaces,developing Azure Databricks applications, and finally, running Azure Databricks in production. This short guide summarizes these patterns into prescriptive and actionable best practices for Azure Databricks. Unsurprisingly, these patterns are also in-line with modern Cloud-centric development best practices. While each ADB deployment is unique to an organization's needs we have found that some patterns are common across most successful ADB projects. Planning, deploying, and running Azure Databricks (ADB) at scale requires one to make many architectural decisions.
