• Disabling session affinity in Azure App Service Web Apps (Websites)

  23 Dec, 2015

  In one of our production systems, we’re using Azure Websites to host a back-end web API. It runs on several machines and benefits from the automatic load balancing we get on Azure Websites. When going through request logs, however, we discovered that of these several machines a few were getting a lot of traffic, some got less and one even only got hit by our monitoring system and no other traffic. That sucks! In our back-end web API we’re not using any session state or other techniques where we’d expect the same client to always end up on the same server. Ideally, we want round-robin load balancing, distributing traffic across machines as much as possible. How to do this with Azure Websites?

• Working with a private npm registry in Azure Web Apps

  13 Oct, 2015

  Using Azure Web Apps, we can deploy and host Node applications quite easily. But what to do with packages the site depends on? Do we have to upload them manually to Azure Web Apps? Include them in our Git repository? None of that: we just have to make sure our app’s package,json is checked in so that Azure Web Apps can install them during deployment. Let’s see how.

• Not enough space on the disk - Azure Cloud Services

  17 Sep, 2015

  I have been using Microsoft Azure Cloud Services since PDC 2008 when it was first announced. Ever since, I’ve been a huge fan of “cloud services”, the cattle VMs in the cloud that are stateless. In all those years, I have never seen this error, until yesterday: There is not enough space on the disk.at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)at System.IO.FileStream.WriteCore(Byte[] buffer, Int32 offset, Int32 count)at System.IO.BinaryWriter.Write(Byte[] buffer, Int32 index, Int32 count) Help! Where did that come from! I decided to set up a remote desktop connection to one of my VMs and see if any of the disks were full or near being full. Nope!

• Replaying IIS request logs using Apache JMeter

  4 Aug, 2015

  How would you validate a new API is compatible with an old API? While upgrading frameworks in a web application we’re building, that was exactly the question we were asking ourselves. Sure, we could write synthetic tests on each endpoint, but is that representative? Users typically find insane better ways to test an API, so why not replay actual requests against the new API? In this post, we’ll see how we can do exactly this using IIS and Apache JMeter. I’ve been using JMeter quite often in the past years doing web development, as it’s one of the most customizable load test and functional test tools for web applications. The interface is quite spartan, but don’t let that discourage you from using JMeter. After all, this is Sparta!

• Automatically strong name signing NuGet packages

  10 Sep, 2014

  Some developers prefer to strong name sign their assemblies. Signing them also means that the dependencies that are consumed must be signed. Not all third-party dependencies are signed, though, for example when consuming packages from NuGet. Some are signed, some are unsigned, and the only way to know is when at compile time when we see this: That’s right: a signed assembly cannot consume an unsigned one. Now what if we really need that dependency but don’t want to lose the fact that we can easily update it using NuGet… Turns out there is a NuGet package for that!
