V ("The V Programming Language", "vlang") is a programming language that first emerged in 2019. A brainchild of Alexander Medvednikov, it is described as a "[s]imple, fast, safe, compiled language for developing maintainable software" 1 , supposedly drawing inspiration from languages like Go, Rust, Swift, C, among others.

In the previous article , we deployed a basic cloud server running NixOS on DigitalOcean and set up a declarative deployment definition for it using Morph. In this part, we are taking it a step further. We will utilize both Morph and Terraform to spin-up a network of 3 web servers …
In the last few months, I migrated both my workstation and my servers (a DigitalOcean VPS and a Raspberry Pi 3) to NixOS. To best summarize the benefits, let's just say that it's like having a "dotfiles" repo, but for your entire system (or multiple!), including custom software, service configuration …

According to a recent thread on Reddit, many people like it simple when doing web development in Go and use net/http with useful addons (like the Gorilla toolkit) instead of a full-fledged framework.
