Bryan Hunter's GigCityElixir 2023 talk on HCA Healthcare's Waterpark system, built on Elixir/Erlang. It describes how the architecture is distributed and fault-tolerant, with a multi-datacenter cluster and runtime code swapping.
HN recommends it as a rare real-world look at a large fault-tolerant Erlang/Elixir system with no downtime in healthcare.

After watching the above which gives one an idea of the Erlang System's capabilities, watch this presentation by Bryan Hunter where the design and architecture of a complete distributed and fault-tolerant Erlang/Elixir system is shown; You get to really see the mind-blowing power of the Erlang System in this - this video
Not code but an excellent presentation of design/architecture of a Real-World fault-tolerant and distributed System in Erlang/Elixir - this video
This is a talk about a large scale, resilient elixir/erlang deployment in healthcare. Specifically they talk about running with no down time using hot code reloading here: this video but the whole talk is quite interesting regarding availability. Warning: the video is quite quiet.
To add to this topic, people who do not know about erlang's hot code loading should watch this talk : this video A multi-DC running cluster where parts are progressively swapped at runtime. No database, only OTP.
This video may be of interest to you: this video Bryan Hunter explains how they do it at HCA healthcare (not specifically LiveView process, but processes in general).
