Ask HN: What can DevOps learn from the recent DDoS attacks?

Think about it...thousands if not millions of devices on different networks, hardware, OS, patches being made to act in unison by some hacker code...

Meanwhile, it sometimes takes many tries to install a simple docker daemon properly using Ansible, Chef or Puppet over a corporate network, having all the necessary permissions, on a perfectly standardized set of hosts.

What can we learn from the setup which made this DDoS attack possible to improve our daily DevOps tasks?

OK...yes...and security.
