AKS Node Troubles

I’ve been having lots of fun this past week running some interesting experiments on Kubernetes. For simplicity, I created a single-node AKS (Azure Kubernetes Cluster) using a B2S instance on Azure. Everything worked perfectly until Friday afternoon. At some point, I noticed that every operation on the cluster appeared to...

Viasfora v4.0 Update

For the past few months, I’ve been slowly improving my Visual Studio Extension, Viasfora. Version 4.0 was recently released, and besides regular bug fixes and some much needed refactoring, I also implemented a brand new feature: Rainbow Lines.

API Management Sign-in Tenant

Azure API Management supports multiple identity providers for the Developer Portal. One of these is Azure Active Directory.

ARM Extensions for Visual Studio Code

I’ve mentioned before that Visual Studio Code has been my tool of choice lately for writing Azure Resource Manager (ARM) templates. I’d like to mention some reasons I’ve found this a great combination: VSCode is far more lightweight than the full Visual Studio. I’ve always found the deployment experience for...

Azure API Management - Getting Query String Values in set-body

Ran a question recently that was a bit tricky to solve with Azure API Management: How do you get a value passed in the URL Query String to your API operation from a policy in a <set-body> statement? For example, let’s assume that the query string value we want is...

Azure API Management - SOAP-to-REST date/time handling

I’ve been spending some time recently helping customers getting started with Azure API Management, and recently ran into a small issue with the SOAP-to-REST feature that might trip others.
