I work as a Cloud Consultant for “OGD ict-diensten” (Netherlands) where I consult different companies about making better use of cloud techniques and transforming their application to the cloud. Before that I worked as a (lead) SysOps engineer for a couple of years. During this time I focused a lot on automating work to free up resources and optimize the work to make sure the customers could be served with a small team of dedicated people. I also write on my blog https://www.autosysops.com where I share insights I have gathered during my IT career.

You’ve got the Power (Platform)! Controlling developers in Azure DevOps

Developers have it all figured out with their code flows, everything is quickly pushed to production and it’s up to the processes to make sure nothing breaks down. But does this always work?

During this talk I will show you how to create extra controls on Pull Requests in Azure DevOps, which need to be passed before a piece of code is accepted. This is achieved by connecting to the Power Platform with Logic Apps and Power Apps. To make sure this process stays very user friendly, Power Apps are used to create a front-end to manage these extra steps.

Do you want to make sure your developers follow your processes without giving them extra work or more tools to learn? I bet you do! So join this talk and learn how to do this.

DNS Disasters: A Hybrid story

The latest priority 1 incident has been resolved and the root cause analysis again points towards DNS. This protocol which enables so many possibilities also causes so many problems.
Let’s look at the hybrid environment of our latest victim and analyze where things went wrong during their journey to the cloud. We’ll look at what caused them to end up with an DNS environment nobody understands anymore.

I will show you how to get out of this DNS disaster by utilizing Azure DNS features. Get ready to dive into the advanced DNS features of Azure and find out how to utilize these while keeping an eye on the customer's business case.

Let’s get rid of these DNS environments which nobody dares to touch! Join me and learn how to transform them into beautiful modern cloud native environments!

Castle in the Cloud: Azure network perimeter defense

In the cloud you want to protect everything with Identity! Although not untrue we still see many developments in technologies like the Azure Application Gateway and the Azure Firewall.

Having all PaaS resources publicly available is not preferred according to current best practices in security. So IT environments are moving back to a more perimeter focused defense where only a couple of points are connected to the wider internet.

During this talk you will learn how to use the application gateway and azure firewall to protect the connected points. You will also learn how to make sure zero trust principles can be applied internally to make a network which is secure and in control.

So if you want to develop a strong defense in the cloud using the most modern techniques then join this session!

Boost your Azure Functions with API Management

Are you wasting precious development time adding authentication and other features to your PowerShell Azure Functions? Stop doing this and start leveraging the power of serverless Azure API Management.

In this talk you will learn how to use API Management to add authentication and you will also learn how to connect to the Azure Key Vault to secure your functions even more. To top it off you will learn how to set this up in a scalable way by utilizing the serverless platform. You will also learn how to set up reusable parts in your API management to save even more work.

So if you don’t want to worry about security when writing PowerShell Azure Functions then join this talk to learn how to offload that!
