Gerenate ARM NSG rules to allow access to an Azure Datacenter
In some Azure environments the organization limits the outbound internet traffic from their servers. There are scenarios where you need to access Azure PAAS services (blob storage, or Azure SQL database etc.). You have to block the access to the internet and enable access to the Azure IP ranges Microsoft reserved for a specific Azure datacenter. To be able to access the service I made a script that will generate the Network Security Groep Rules in ARM format to give access to Azure services.

Create known configuration in your ARM templates with T-shirt sizes
A good way of keeping on top of the configurations deployed in your Azure environment can be done by using T-shirt size configurations. T-shirt Sizes are known working configurations for your ARM templates. By using a T-shirt Size you can take away the complexity from the ARM template consumers. A sample of a T-shirt Size can be a Small, Medium of Large offering from a resource.
In this blogpost I want to show how you can use T-shirt Size configuration in an ARM template. The idea is to deploy a website where you hide all the size setting behind a Small, Medium of Large sizing. The consumer only has two parameters to start the deployment:

Solving 429 http error using terraform on Azure Management API
When adding more resources to my azurerm terraform project, I encountered some concurrency problems. Terraform sends to many concurrent requests to azure. The Azure API gives a 429 http error. The fast solution is just to rerun your terraform apply, but that will not work in an automated environment (Infrastructure as Code). In this blog post I’ll show the error and what you can do to avoid it.
Http 429 Error
Terraform is able to generate graph files in dot (graph description language) format from your deployment plan. With some tooling the dot files be generated into image files. This makes reviewing and talking about Terraform templates easier. You are able to review a visual graph before deployment.

Running Azure PowerShell commands in parallel to speed up your deployments
Making better software starts with shortening the time it takes to get feedback. The less time between you start an action and its result, the bigger the chance you will do anything with the feedback. Faster is better!

Removing deployments with Powershell to solve the ‘DeploymentQuotaExceeded’ error in Azure.
For some time we have been using Visual Studio Team Services Release Manager for our continuous deployments to Azure. Today our Continuous Deployments to Azure Resource Manager came to a halt with the following error:
[error]DeploymentQuotaExceeded: Creating the deployment 'deployModule-0408-0956' would exceed the quota of '800'. The current deployment count is '800', please delete some deployments before creating a new one. Please see http://aka.ms/arm-deploy for usage details.
Unfortunately we had to find out what was going on, before we could do any new deployments. This was very time consuming, because there were only two google hits on the error. They where not very helpful in solving the error.
