DNN Geo-Replicated Deployment in Azure (and Others)

Earlier today I blogged about Geo-Replicated Application Deployment in Azure for those looking for true high-availability deployment. In that article, I noted that it isn't possible to deploy something like DNN to those environments without a bit more consideration. This posting looks at the special considerations, and some potential suggestions to work around DNN in these types of environment.

Geo-Redundant Application Deployment in Azure

Just a little over 24 hours ago a Microsoft Azure datacenter experienced an extreme outage. For those with hosting primarily inside of the South Central US location, it resulted in outages lasting from between 8 to 20 hours, with a few select sites still impacted as I write this. There is a common misconception that if you are in the cloud you are ok. This isn't exactly true, the configuration and deployment of your application within the cloud will be the final determining factor of your stability. It is one thing to be secure/stable with Geo-Redundant backups but is a whole different story to be Geo-Redundant Availability wise. In this post, I'll look into what it takes to be truly Geo-Redundant in Azure and why it is often overlooked.

Improving the Security of Azure App Service Websites

Azure Web App hosting within the Azure App service is an amazingly flexible product. As with any product, with great flexibility comes a plethora of configuration settings that could expose your application to more risk. In this post, I'll investigate settings and configurations that you should validate in your own applications to ensure you are as secure as possible.

Should, When, and How Can I Migrate to .NET Core

Now that we are a few years into .NET Core I am seeing more organizations start to look at the big picture and decide if they want to migrate to .NET Core, or are evaluating .NET Core for consideration on new projects. Over the past few years I've given multiple talks at conferences with the title "Should I Transition to .NET Core? Will It Hurt?" This talk has been very popular so I thought I'd share a bit of context that you cannot get with the slides to help you better understand what might make the best sense for your organization/project.

Reporting Code Coverage in VSTS with .NET Core

Recently I decided to go back to using VSTS for my CI/CD processes after having some great experience with it on a project. As I evaluated the processes that I was following, one thing was missing from my existing CI process, and that was reporting on Unit Test Code Coverage for my .NET Core projects. I'll admit, it was something that I hadn't exactly looked at in a while. When I first started with .NET Core Code Coverage was a "Coming Later" feature and I wasn't too concerned about it. Searching for solutions I found a plethora of crazy recommendations and using the out-of-the-box VSTS build process for .NET Core did not get me what I wanted. In this post I'll walk through the process to properly get Code Coverage Calculated with each build, this will also allow the "Test" -> "Analyze Code Coverage" option to work in Visual Studio.

2018 Nebraska Code Presentations

Last week I was a speaker at Nebraska Code, held in the Omaha, NE area.  It was a great event, and although I had technical issues with one of the session it was still another great event.  For those that attended my talks, this post contains the slides etc.

Managing Dependency Injection in .NET Core

.NET Core's support for Dependency Injection is quite amazing. However, I still see projects that implement some bizarre solutions for things that are not that complicated. One of these items is how you configure dependency injection for assemblies that make up a project but might not be part of the main project.

Using Multiple Authentication/Authorization Providers in ASP.NET Core

I find that in many cases application developers need to create web applications that can support not only the web application itself but an API that might be used by a Mobile Application or otherwise. I have seen some methods used in the past to create these two interfaces, everything from home-grown security to the creation of two separate applications that do the same thing. With ASP.NET Core we can use multiple authentication providers so we can easily support various providers and control when each should apply. In this post, I explore the process of supporting multiple authentication providers.
