If you're juggling multiple incompatible versions of application servers across multiple platforms across multiple datacenters and multiple cloud providers with multiple dev teams... you're gonna see some real value to those kinda of "solutions". It's not random that this tech is coming from cloud leaders and Entprise shops, and they don't address problems common to development, they address problems common to cloud apps and cloud heavy Enterprise shops.

I think Assembler looks like ass and it doesn't add much to how I want to program... It's still frequently used, though, because it solves problems other than the ones I have.

We have a bunch of apps that run based on some type of external event - a time interval (Nomad supports cron like scheduling across an app pool), a file coming in, an external event, etc.

We submit a job via the api and it runs the job on whatever server has available resources. We specify the mininimum amount of RAM and CPU needed to run a job. If too many jobs are queued on a regular basis, we can either add more RAM or CPU to an existing instance or add another instance and install a Nomad agent.

Yes I know k8s can do the same thing but we don't have to use Docker, we can though.
