Interesting talk about using Erlang (and Elixir) for managing hospital patients.

We have to be continuously available. This is not just high availability. We just can’t ever go down. That means that we can have no unplanned outages. We have to be fault-tolerant. We have to, you know, be fault-tolerant so we don’t fail by mistake. If we fail, we need it to be limited. We also need to not have any planned outages. We can’t take downtimes for patching or releases.
