Azure Deployment Stacks
Infrastructure‑as‑code in Azure has long been powerful but fundamentally stateless: ARM and Bicep deployments push resources, but Azure never truly remembers what belongs to what. That gap becomes painful in large, regulated, or multi‑team environments where lifecycle control, drift detection, and predictable updates are non‑negotiable. Azure Deployment Stacks change the model entirely by introducing a stateful, lifecycle‑aware deployment engine built directly into Azure Resource Manager. In this 45‑minute technical deep dive, we’ll dissect Deployment Stacks from the inside out—how they track resource ownership, enforce lifecycle rules, prevent accidental changes, and bring Terraform‑like state management natively into Azure. You’ll learn how to design stack‑based architectures for landing zones, shared services, and platform components, and how to use stacks to enforce guardrails, manage drift, and build defensible, auditable deployment workflows.
Inside Azure Resource Graph
Azure environments often contain thousands of resources spread across subscriptions, management groups or even tenants. Traditional discovery methods simply can’t keep up with this complexity. Azure Resource Graph (ARG) changes the game by giving engineers, architects and operators a fast, scalable, and query‑driven way to interrogate their entire Azure environment in seconds. In this 45‑minute technical deep dive, we’ll go far beyond the basics of Azure Resource Graph. You’ll learn how Azure Resource Graph works under the hood, how to craft high‑performance Kusto queries that surface architectural drift, security gaps and compliance deviations. Expect live queries, real‑world patterns, and practical techniques you can apply immediately to gain clarity in even the most complex Azure platforms. This session is designed to elevate the visibility, strengthen governance, and build defensible insights into their Azure landscape.
Inside Entra ID Authentication
This session brings you deep into the world of Entra ID Authentication - definitely a must-know for everyone who works with Entra ID! Marcel, a Microsoft Regional Director and Azure MVP from Switzerland will be your guide on the bumpy roads to authentication procedures, App registrations, OAuth, Access and ID Tokens and much more. Don't miss this essential session!
Demystifying Azure AD Applications
Did you ever wonder what Application Registrations and Enterprise Applications in Azure AD are used for and how they work? And what the many settings are used for? No worries, these rocket-science-like objects will be discussed and explained in this session by Microsoft Regional Director and Azure MVP Marcel Zehner. He will reveal what you wanted to understand for a long time already.
Kill your IAM system now - Entra ID is here!
Identity and access management (IAM) requirements have dramatically changed in the last years. With more and more companies heavily consuming cloud apps, new tools and processes are needed to address modern IAM needs. In this session, Marcel Zehner, a long-term Microsoft MVP and Regional Director, will demonstrate from real-world business cases, how comprehensive IAM solution can be built with Entra ID instead of using clumsy, cumbersome, not-so-modern IAM solutions.
DNS in hybrid cloud environments - can it be that hard?
In short, no, DNS is not simple. It has been around for decades and is an essential component of a hybrid cloud environment. Despite this, many environments still struggle when it comes to designing rock-solid, hybrid DNS solutions, and trust me, it comes with a lot of pitfalls! After attending this session you know what you need to know - and how to avoid name resolution disasters.

A deep dive into Azure bIlling
Most technical Azure session focus on Azure platform and application landing zone topics. Modern cloud governance lives or dies on how well an organization understands and automates its billing structure. This technical breakout session unpacks the core building blocks of Azure billing, explaining their purpose, relationships, and impact on cost management, chargeback, and organizational governance. It equips engineers, architects, and FinOps‑minded practitioners with a clear, code‑driven understanding of Azure’s billing hierarchy and how to operationalize it at scale.
