Export Azure RateCard data to CSV with C# and Billing API

The Azure Billing API allows to programmatically read Azure costs. On the one hand, there are is the usage of your resources (how much [unit] you already used for [resource]), on the other hand there are the basic costs for resources – so e.g. the costs for a storage account or a specific virtual machine in a specific region. Each of these two use cases has its own API: the RateCard API which returns the potential costs of the resources (“basic costs”) and the Resource Usage API which returns the usage of your resource of a subscription.

In this blog post, I’ll focus on the RateCard API. There is a sample available on GitHub, but when I used it, I ran into some issues. So I decided to developed a simple C# console application and blog about my experiences. The application reads data from the RateCard API and creates a CSV file out of it. The CSV file can be opened in Excel and should already help to do some calculations.

The application/this post is mostly inspired by: https://github.com/Azure-Samples/billing-dotnet-ratecard-api.

Update February 7, 2017: I built a .net library and published it as NuGet package which you can use to get data from the usage api and the ratecard api. The library also combines the usage and ratecard data and calculates the costs. The code is published on GitHub and I blogged about the usage and the configuration of it:

This blog post is still valid, it shows the how to configure and build an application that uses the Azure Billing RateCard REST API.

Connect Azure App Service to virtual network

Let’s assume you have to read data from your on-premise network e.g. from a SAP, ERP or other system. It could also be that you want to have access to your virtual machines in your virtual network.
How to connect to your on-premise environment? Simple answer is: via VPN or ExpressRoute! But that’s just a part of the job, you also have to connect the App service to your virtual network at first. If the web app is in the virtual network, you have access to all resources in the network – virtual machines for example. If the virtual network is connected to your on-premise network, you can also access those resources. This blog post is about how to connect the app service to your virtual network and how to design the network. The VPN connection is not part of this blog post.

Overview

The connection between App Service, virtual network and on-premise network needs the following resources:

  • App Service + Web App/API App/Logic App/Function/…
  • Virtual network
  • Virtual network gateway
  • Point-to-Site VPN from Web App etc. to the virtual network gateway
  • Local network gateway
  • Site-to-Site VPN from Azure virtual network gateway to the local network gateway (VPN device)

Auto shutdown Azure virtual machines

I already blogged about how to Automatically shutdown virtual machines in Azure. The previous post is still useful if you want to shutdown a group (or all) of virtual machines at the same time. It uses the automation service to get the virtual machines and shuts them down. So you can control it at one place.

At November 22, 2016, Microsoft announced a new feature which makes it easy to configure the auto shutdown for a virtual machine: https://azure.microsoft.com/en-us/updates/set-auto-shutdown-within-a-couple-of-clicks-for-vms-using-azure-resource-manager/.

This new feature is available in the Azure portal. Just navigate to your virtual machine, scroll down to “Schedules” and select “Auto-shutdown”:
