Today’s post is about the Logic Apps billing model. As you might know, the Integrated Service Environment has been generally available since May 2019. Since then, there is a consumption plan and a fixed price approach for Logic Apps. Lately I have noticed that this still remains confusing… Let us try to demystify this one then? 😉

Aside from the variety of technical questions, a very common discussion around Azure Kubernetes Service (AKS) is … “What will it cost me?”. In today’s post we’ll dissect how the pricing dynamics work and how you can optimize the cost for your cluster(s). Where this might not be rocket science, I do have noticed some organizations struggling with this. So with this I hope to help those out… 😉

The “BulkUploader” module of VMchooser has existed for quite some time. It is without doubt the most loved capability by all the visitors/users. Though where many are accustomed to working with the CSV Input file, do know that you can now also use the export files of Azure Migrate! For today’s post, let’s go through the process…
Let’s take a look
Go to your Azure Migrate project

Today’s post will be about “demystifying” the possible network costs you might incur when using Azure services. Once you understand the basics behind the billing model, you’ll soon find that you can tweak these to your advantage!
When looking towards the costs, there are several pricing pages you should visit to know the cost drivers of your architecture…
Though I can feel you… It’s not always easy to understand when what is triggered.
- 23/08 – Updated HL overview to v2.0 to include costs due to zone architecture
- 23/08 – Source files for the drawing can be found here.
High Level Overview
Underneath you can find an overview of the possible cost drivers. We’ll go into depth on the individual flows in this post.

A lot of workloads are driven by peak consumption. From my experience, there aren’t the amount of workloads that have a constant performance need are in the minority. Now here comes the interesting opportunity when leveraging serverless architectures… Here you only pay for your actual consumption. So if you tweak your architecture to leverage this, then you can get huge gains!
For today’s post, I’ll be using VMchooser once again as an example. A lot has changed since the last post on the anatomy of this application. Here is an updated drawing of the high level architecture ;
Underneath you can see the flow that’ll be used when doing a “Bulk Mapping” (aka “CSV Upload”). The webapp (“frontend”) will store the CSV as a blob on the storage account. Once a new blob arrives, a function will be triggered that will examine the CSV file and put every entry onto a queue. Once a message is published onto the queue, another function will start processing this message. By using this pattern, I’m transforming this job into parallel processing job where each entry is handled (about) simultaneously. The downside of this, is that there will be contention/competition for the back-end resources (being the data store). Luckily, CosmosDB can scale on the fly too… We can adapt the request units as needed; up or down! So let’s do a small PoC and see who this could work…

Remember the last time you went shopping for a shirt? Then you surely also recall the moment in time when you were looking to find the right shirt size for yourself…
You probably also noticed that sizes might differ a bit depending on the context. A woman’s size vs & men’s size is totally different. There are geographical differences… and some people just like to wear cloths that have more “free space”.
So is today’s post about buying cloths? Hell no… 😉 But it’s to point out that there are analogies between finding the right shirt for you, and finding the right Azure Virtual Machine. Today we’ll delve into the aspects that will guide you a given T-shirt size in Azure ; for instance, why choose an FS1 above an A1_V2, where they both have 1 core & 2GB of memory. Though there is a price difference of 10€ per month on them.

During the weekend I saw the following tweet passing by …
Apparently, a hosting company (allegedly) got all their data wiped by an ex-admin. Now I can imagine people thinking that this is something that is part of the territory when it boils down to cloud. So I wanted to write a blog post entailing what you do to set up a governance structure in Azure. Here I’m aware that the above tweet is more related to the security aspect of governance, it’s a part of it nevertheless.
Let’s get started on our scope… IT Governance can cover a lot of ground. In essence, the goal is to assure that the investment in IT generates business value and the risks that are associated with IT projects are mitigated. Though I found that CIO.com has a nice definition on it ;
Simply put, it’s putting structure around how organizations align IT strategy with business strategy, ensuring that companies stay on track to achieve their strategies and goals, and implementing good ways to measure IT’s performance. It makes sure that all stakeholders’ interests are taken into account and that processes provide measurable results. An IT governance framework should answer some key questions, such as how the IT department is functioning overall, what key metrics management needs and what return IT is giving back to the business from the investment it’s making.
So let’s take a look at how we can put an enterprise-grade structure around the management of Azure!
TL;DR = Azure Enterprise Scaffold
For those who want to skip the post below… When talking about governance in Azure, the best place that summarizes it the following page in our documentation ; “The Azure Enterprise Scaffold“.

In my role as a Cloud Solution Architect, I’m often faced with the statement that cloud is expensive. My reply is always that Cloud is not expensive (more expensive than On Premises) if you take into account all the costs involved. As this is an easy statement to make… I made an effort to create a cost comparison for four different scenario’s (in term of deployment size) and stacked “OnPremises” vs “Cloud”.
In this post we’ll discuss this calculation and ensure that we are comparing apples to apples!

Did you know that the “Dev/Test Labs” service in Azure had a neat feature where you could schedule the shutdown of servers? No, or yes… Now this features has been integrated in all virtual machines. Nice!
So just go to the details blade of a virtual machine and click on the “Auto-Shutdown”-tile. Here you can enable / schedule a shutdown.
Via this method, you configure it per VM. You can always use Azure automation / runbooks and do it per resource groups.
Why do this? In Azure you are billed per minute for your compute runtime. So shutting down (and deallocating) will safe you a great bunch!
