One thing I wasn't able to grok from the article is orchestration of VMs. Are they using AWS to manage the VM lifecycles, restart them, etc?

Last time I looked into this for on-prem the solutions seemed very enterprise, pay the big bux, focused. Not a lot in the OSS space. What do people use for on-prem VM orchestration that is OSS?

Depends what is your scale, but I used oVirt and Proxmox in the past, and it was (especially oVirt) very enterprisey but OSS.
