We proved that self-healing works not only with services but also with infrastructure. We are getting close to having a self-sufficient system. The only thing missing is to find out a way to add self-adaptation applied to infrastructure. If we accomplish that, we'll be able to leave our system alone. We can go on vacation knowing that it will be operational without us. We could even go to one of those exotic places that still do not have the Internet. Wouldn't that be great?
Even though we are one step closer to our goal, we are still not there yet. We'll take another break before moving on.
We'll continue the practice from previous chapters. We'll destroy the cluster and save us from unnecessary cost.
