How to host ASP.NET websites on AWS (15 part series)

When we started with jodiBooks, Diana was fully in charge of creating and hosting our applications. My job was, well, to have a job and pay the rent. Back then, we decided it would be the best choice to start with the tools she was familiar with. That meant writing our applications in C# in the ASP.NET MVC framework. Two years later, I quit my job and started to assist with coding.

In the last 6 months we learned that we both have our strengths in this process. Diana is clearly the better software engineer, but I'm the better system administrator. Now that I started researching other hosting options, we quickly learned that we were using "old" techniques. Virtually everyone (well, everyone who writes tutorials) is using the .NET Core framework or something completely different (Node.js/JavaScript).

Host ASP.NET websites

In hindsight, we completely didn't research this at all. We just took what we (Diana) knew. Now we had a problem as migrating from ASP.NET to .NET Core is not a trivial exercise. It will take months to do this. Also finding documentation, tutorials and manuals on how to host ASP.NET sites are (getting) rare. Most are written with .NET core in mind. That's why I wrote this extensive manual on our website.


The tutorial shows how to host ASP.NET web applications in the AWS cloud. It describes how to use and configure the following AWS services:

The applications are hosted on a Windows 2019 machine in IIS 10. The database is run on the same machine in SQL Server Express 2017. As a bonus part 13 shows how to run a WordPress site on EC2.


The tutorial also discusses the cloud architecture used. What I often miss in tutorials and manuals, is a basic sketch of the architecture. I don't have the skill of parsing the abstract ideas used by software engineers and experienced system administrators. I need to see what parts are used and how do they link together.

In this guide and all the ones I will write after, I'm going to include these sketches. I know that will be challenging, as for now the architecture is still really simple. As it grows, making these images will become more and more challenging. Especially as I want to make them comprehensible, not a big ball of spaghetti smacked flat in a 2D image.

A possible future architecture. Our goal is to have migrated to .NET Core and containers by then.
