Nomad VS Juju

[Nomad]

Lob’s core API has been fully migrated to HashiCorp's Nomad, Lob’s Next Generation service platform. This is a major milestone for the Nomad Project, the Platform Team, and Lob Engineering. This migration is the culmination of a year of R&D, months of practice migrating other Lob services, and weeks of work on this particular service. It’s absolutely worth celebrating for the complexity and customer impact.

Most of our API’s migration to Nomad happened in August, but the key feature of autoscaling was not working as expected. This turned out to be a bug in Nomad which James Douglas tracked down. The issue was recently fixed and autoscaling works as expected, completing the migration!

There's also https://pot.pizzamig.dev/ which even has a Nomad(https://www.nomadproject.io/) driver in case you want to "orchestrate" the jails(as in deploy many jails at the same time across multiple servers)

The check stanza runs a health check on the service Since the service is registered to Consul, the health check runs on Consul. The above health check is configured to run every 10 seconds, and is given 5 seconds for the health check query to succeed. Health checks in Nomad are similar to Kubernetes health checks.

Not sure if it fits here, and might be a little more complex than what you’re looking for, but Nomad is definitely worth a look.

I'd like to also mention hashicorp nomad + consul. They're worth evaluating.

We had a hard time finding this data when experimenting with carbon aware scheduling in Nomad. There seem to be a lot of orgs working on this, but it’s all third party as far as I know. I couldn’t find a first party (eg Amazon, Microsoft, Google, etc) that provided this data via an API. Very frustrating.

There are a couple resources linked here: https://github.com/hashicorp/nomad/blob/h-carbon-meta/CARBON...

The silver lining is that the folks who are working in this space are extremely friendly and passionate in my experience. Don’t be scared to “contact sales for an API let.” The few folks I talked to were extremely helpful.

Each app is packaged in a charm which seems to be a yaml declaring inputs, dependencies and other meta data and optional python code that can respond to certain lifecycle hooks

Kubernetes Custom Resources were created to allow the Kubernetes API to be extended for domain-specific logic, by defining new resource types and controllers. OSS frameworks like operator-sdk, kubebuilder and juju were created to simplify the creation of custom resources and their controllers. Tools built with these frameworks came to be known as Operators.

At Canonical I work on two open-source projects written in Go: Juju, a large cloud-based application deployment tool, and Pebble, a small Linux service manager. Both include CLI clients and API-based server daemons. Juju in particular is a large distributed system.

Are you talking about this[1]?
