I make my living as a CFEngine consultant. CFEngine runs every 5 minutes (it's lightweight enough to do that). The evolution was: CFEngine 1 ran once a day; CFEngine 2 ran once an hour; CFEngine 3 runs every 5 minutes. Self-healing infrastructure.
The concept of self-healing is a bit weird for me. Surely you want to investigate the cause before it heals?
Funny that we have tools like tripwire which have the opposite idea of the world.
My dream would be to have both functionalities in a single tool.
Bidirectionality! If you solve a problem on one machine you could pull that fix then push the same fix out to other machines as a preventative measure.
