Nomad is simple on the surface and could have been a great tool - but it is basically unusable on its own without tighter integration with Hashi’s own tools (eg Vault). Configuring and maintaining all those things is nontrivial and ends up being more annoying (for a lesser end result) than just using a fully managed kubernetes cluster like GKE
The only negatives about Nomad is the Hashicorp license drama that has happened recently and persistent storage can be a pain in the ass.
They pulled the rug out on a lot of people and people tend to hold grudges. Community edition is peanuts compared to using an open source tool you _could have_ fixed your own bugs with by creating PRs or adding features with PRs. I used to be a huge hashicorp fanboy... _used to_.
