Getting control over your deployment pipelines to Microsoft Azure Resources Manager with VSTS
When deploying resources on Azure with Azure Resource Manager you want to be in control of which resources are deployed and control their life span. To get the control you need to do deploy in a tested, standardized and reusable manner. This can be done by managing your resource creation as Infrastructure as Code.

Handling flushing of the application insights messages when asp.net core shutsdown
When running a ASP.NET Core web application there are cases when you need to do some logic when the application stops. An example: you are logging and have to flush the last message to the log (Application Insights). In that case you need can add an event in the
Configure method. In this post I show a short example of how to do this.

Creating multiple blobs, move/rename blobs and delete blobs with advanced runtime bindings in Azure Functions.
The standard input and output bindings in Azure Functions are written in a declarative pattern using the function.json. When defining input and output declarative, you do not have the option to change some of the bindings properties like the name or make multiple outputs from one input. An imperative binding can do this for you. In this blog post I’ll show how to use imperative blob bindings.

When you are developing Powershell scripts, creating some unit tests will help you in monitoring the quality of the scripts. Writing some tests will give you some assurance that your code still works after you make some changes. Writing Powershell unit tests can be done with Pester. Pester will enable you to test your Powershell scripts from within Powershell. It is a set of Powershell functions for unit testing Powershell. These functions will allow you to mock and isolate the Powershell code under test. When you want to integrate your unit test into your VSTS build pipeline, you need an build extension to run then in your build pipeline.

Create a VSTS release pipeline for Azure Functions
Azure Functions enable you to easily run small pieces of code in the cloud. To do this right, you need to setup continuous delivery of the infrastructure and the code involved. Otherwise you will end with an uncontrolled environment where nobody knows what code is actually running. In this blog post I’ll describe how to setup a deployment pipeline for Functions with VSTS. This will enable you to deploy Functions as Infrastructure as Code.
From an deployment perspective an Azure Function contains of two parts:
- Azure infrastructure
- Function code
Both the ARM template and the code can be deployed from VSTS. By doing this, you can manage functions like any other Azure resource.

In my previous blog post Lock Azure resources to prevent accidental deletion, I showed how to add a lock to a resource with an ARM template to protect it from accidental deletion. When you want to delete the resource, you first need to remove the lock. A lock cannot be removed with an ARM template. To remove the lock you can use:
- Rest API

How a lock can prevent user from accidental deletion of a resource.
In some cases you want to protect critical resources from accidental deletion. Some examples are a storage account with source data for processing, a Key Vault with disk encryption keys, or another key component in your infrastructure. When losing some resources that are key in your infrastructure, recovery can be dramatic. Resource Manager locks will enable you to protect these critical resources from deletion.
Resource Manager locks
Resource Manager locks apply to the management function of the locked resources. The locks do not have any impact the normal functions of the resource. You have two possible types of locks on a resource:
Locking down a resource can save your contributors from accidently delete a critical resources. An ‘oeps… I deleted the wrong resources’ moment should be a thing of the past.
CannotDelete means authorized users can still read and modify a resource, but they can’t delete the resource.
ReadOnly means authorized users can read a resource, but they can’t delete or update the resource. Applying this lock is similar to restricting all authorized users to the permissions granted by the Reader role.
