Someone is DDoS-ing my Azure Functions, and here is what you can do

October 26, 2022

Last week, all of a sudden, my Azure subscription got suspended. As the subscription runs on credits and is optimized to be way below the limit, I was surprised to see that I suddenly reached the spending limit. Usually, the monthly cost for the subscription is around 50-60 EUR. This month, it suddenly got above 150 EUR, but why?

#DevHack: Authenticate Azure Web PubSub with Azure Functions

July 26, 2021

This week, I tested out the Azure Web PubSub service, which is still in preview when writing this article. The Web PubSub service is a real-time messaging service that allows you to use the WebSockets APIs and the publish-subscribe pattern. It is excellent for collaborative applications.

For Squarl, I started to implement a couple of improvements for the back-end running on Azure Functions. I created these functions with TypeScript. In the past, I used webpack and later Azure Funcpack to bundle my functions to one file per function. That way, the host does not have to do all those read actions for retrieving the dependencies.

Using OAuth On-Behalf-Of flow in a Node.js Azure Functions

While implementing a couple of Azure Functions, I needed to use the OAuth 2.0 On-Behalf-Of flow. With this flow, you can allow, for instance, an API to perform tasks on your behalf. This flow is great when you want to offload some of the work from the front-end or perform additional calls on the back-end when processing data.

We held the event virtually due to Covid-19, like most of the events in 2020. We decided that we wanted to do this as a virtual event together around May/June timeframe to make sure we could let it happen.

#DevHack: Simple caching in Node.js Azure Functions

October 12, 2020

Azure Functions do not have an out-of-the-box caching mechanism. For caching, the recommended way would be to use a distributed cache like Azure Cache or Redis. These services each come with their price tag and might be too robust for the cache you want to create or need. For Azure Function created with C#, you can use the good old memory cache.
