Marcel Meurer im Portrait – Generation Cloud

Seit 2003 arbeite ich für die sepago GmbH in Köln. Als ausgebildeter Ingenieur für Elektrotechnik war und ist IT das, was mich bewegt und motiviert. Dabei sind 16 Jahre eine lange Zeit – in der IT immerhin mehrere Generationen. Spannend bleibt es aber immer. Ein besonderes Momentum, wenn nicht sogar eine Evolution, ist die Nutzung der Cloud und der Fokus auf das Wesentliche. Statt IT-Infrastrukturen zu planen und zu betreiben liegt heute der Fokus auf das Umsetzen von Ideen.

CDC Germany: RDS & Windows Virtual Desktop – Desktops in 2019+

From 21. to 22. April the annual Cloud and Datacenter Conference took place in Hanau/Frankfurt in Germany. It’s one of my favorite community events in Germany. This year I was allowed to contribute something to RDS in Windows Server 2019 and Windows Virtual Desktop – including Windows 10 Multi Session Host and FSLogix (an awesome combination).

I published my slides to


My demos are also available via youtube:

Publish your solution to the Azure Marketplace

Publishing own solutions to the Azure Marketplace seems to be very easy by using the documentation on To avoid any pitfalls I wrote down some insights about my first approach. In this blog, I will focus on “Azure Applications”

The Cloud Partner Dashboard

Make sure that you have access to the Cloud Partner Portal at In my case, I use my coopered credentials to log in.
Assign your Dev Center account details via Publisher Profile:

I had some trouble doing this.

Why configuring Azure AD authentication with an Azure Web App fails

I spent hours today adding Azure AD authentication to an Azure MVC web application with Visual Studio. I always got the same error while adding the preconfigured AD application:

“Error: Unable to query for Azure AD applications: An error occurred while processing this request.”

My account has the right permission in Azure AD – I thought. After a while I found out: Visual Studio was connected to my Azure AD with three different accounts:

Deploy an Azure Functional App as an interface to Log Analytics / Azure Monitor


Microsoft offers with Log Analytics a cloud-based big data service. Log Analytics is used by several services (including Azure itself) to log and analyze data. It’s a core component of Azure Monitor and Application Insights.

Log Analytics key facts:

  •  Cloud-based
  • No data aggregation
  • Pay per upload and data retention
  • Powerful query language (kql: <>)
  • Direct support for visualization on

I use Log Analytics for several projects where data aggregation and analyzation are main tasks.

Creating devices for Azure IoT Hub with SAS token automatically

A few weeks ago, I started an IoT project with a company responsible for a huge amount of different buildings around the world. We deployed several virtual and physical sensors in Azure IoT Hub. Doing this we had three challenges:

  • Deploy new IoT devices in Azure IoT hub in a batch
  • Generate SAS tokens for these IoT devices
  • Generate SAS tokens even if a device still exist in Azure IoT Hub

The requirement of batch processing avoids the use of the Device Explorer to generate SAS token.

OneDrive PowerShell Module – Added support for OneDrive for Business

More than two years ago, I created my PowerShell module to access OneDrive. This module can be installed with a one-liner from

Again, I was asked to support OneDrive for Business and finally, I’m ready: From version 2.0.0 OneDrive for Business is supported.


I provide the complete documentation on GitHub, where I will maintain it:


Here is the summary of version 2.0.0:

Working with the OneDrive PowerShell Module

Recently I got some questions on how to work with my PowerShell module for OneDrive. Therefor, I put together some examples.

Remember: The OneDrive module is for OneDrive personal and doesn’t work with OneDrive business / Sharepoint.

First: Register an app (authentication) for OneDrive:

Authenticate to OneDrive

Show files and folders

Create new folder in OneDrive

Copy files from local to OneDrive

Copy file from OneDrive to local disk

Delete file in OneDrive

Logging Azure AD audit and sign-ins to Azure OMS Log Analytics

Azure OMS Log Analytics is often used by Azure services. Unfortunately, Azure AD audits and sign-ins are not configurable for log analytics now (I bet this will change soon). But for now, we must work around to archive this.

My favorite way is:

Sending audit logs and sign-ins to event-hubs -> collecting event-hub data from Logic Apps -> transferring data to Log Analytics

Creating an Event Hub namespace

Create a new event hub namespace in Azure with the Azure Portal.
