I'm a huge fan of Pulumi and I've had the need to create an AKS cluster recently so thought I'd give it a go with Pulumi. It turns out that adding an Application Gateway isn't the easiest thing to do. What is Application Gateway? Azure Application Gateway is the Layer 7 (HTTP level essentially) load...

Does OpenTelemetry in .NET Cause Performance Degradation?
Contrary to Betteridge’s Law of Tabloid Headlines, the answer is “yes,” but context is important. I get this question so often that I thought it was time to get some stats on it.
12 Factor Apps and Modern Observability

Evil Monkeypatching in C# with Rosyln Source Generators
I came across this as I was trying to find a way to add a shim onto a sealed class from the Microsoft BCL. The goal was to provide a package that allowed people using that class to get a wrapper very easy without having to change their code.
Authenticating with AWS API Gateway with IAM credentials using Javascript and Node
Unfortunately, having server-side code call the AWS API Gateway isn't that easy. It requires signing of requests, and the AWS SDK's don't make that easy to access.
