Great thread! There's $$$ of value in here. One could easily scrape this page an build an automation resource site ;)
Google Cloud and K8 for orchestration. Autoscaling with kubectl in a single command.
Twilio SMS API is also great. Not quite at the point where I can send a text to a machine in human language and have it launch services. But pinging from phone, receiving health reports, alerts, etc. Very reliable and secure.
