An Application Study in Serverless and Azure with 'The Urlist' — Burke Holland Cecil Phillip, both of Microsoft, have built a site for creating and sharing lists of URLs which is also designed to be an exemplar of a serverless app running on Azure. It uses TypeScript and Vue.js on the frontend, C# in the back, and in this post they share how it’s structured. The code is on GitHub, naturally.

The Lifecycle and Performance of a Lucet Instance — Lucet is a native WebAssembly compiler and runtime that Fastly are working on with the aim of being able to rapidly execute WebAssembly on every HTTP request a server might receive.. such as for, say, a serverless platform 😄 This is a pretty technical look at how they get things so fast and how this could ultimately make serverless functions a lot faster soon.
