Join this hands-on meetup designed for professionals preparing for the Azure Databricks Platform Architect Accreditation, with a strong focus on real-world deployment patterns, security architecture, and enterprise-grade governance. This session goes beyond theory to demonstrate how modern data teams design and operate scalable Lakehouse platforms on Azure.

We will walk through practical scenarios such as deploying a workspace using Azure Resource Manager (ARM), configuring VNet-injected architectures for private network control, and implementing Secure Cluster Connectivity (no public IP) for production environments. Participants will explore how to integrate Azure Data Lake Storage Gen2 using Access Connectors (managed identities), applying correct RBAC roles like Storage Blob Data Contributor for secure data access.

The session also covers architect-level governance using Unity Catalog, including managing identities via Azure Active Directory (Entra ID), setting up fine-grained permissions, and enabling cross-workspace data sharing. We will demonstrate Private Link setup, DNS configuration, and UDR-based traffic routing for secure hybrid connectivity.

Attendees will gain hands-on insights into building pipelines, controlling cost, and troubleshooting workloads using query profiles, monitoring tools, and network diagnostics, preparing them to confidently design, secure, and optimize enterprise Databricks solutions aligned with certification standards.

Question 1: First-party service benefits
