Packet Pushers 333 Automation & Orchestration in Networking
http://packetpushers.net/podcast/podcasts/show-333-orchestration-vs-automation/

While the discussion is all about NETWORK DevOps, they do a good job of decrying WHY current state of system orchestration is so sad – in a word: heterogeneity.  It’s not going away because the alternative is lock-in.  They also do a good job of describing the difference between automation and orchestration; however, I think there’s a middle tier  of resource “scheduling” that better describes OpenStack and Kubernetes.

Around 5:00 minutes into the podcast, they effectively describe the composable design of Digital Rebar and the rationale for the way that we’ve abstracted interfaces for automation.  If you guys really do want to cash in by consulting with it (at 10 minutes), just contact Rob H.

Need PXW? Try out this Cobbler Replacement
https://robhirschfeld.com/2017/04/11/provision-preview/ 

INTRO
We wanted to make open basic provisioning API-driven, secure, scalable and fast.  So we carved out the Provision & DHCP services as a stand alone unit from the larger open Digital Rebar project.  While this Golang service lacks orchestration, this complete service is part of Digital Rebar infrastructure and supports the discovery boot process, templating, security and extensive image library (Linux, ESX, Windows, … ) from the main project.

TL;DR: FIVE MINUTES TO REPLACE COBBLER?  YES.

The project APIs and CLIs are complete for all provisioning functions with good Swagger definitions and docs.  After all, it’s third generation capability from the Digital Rebar project.  The integrated UX is still evolving.
