Faults, scaling and Erlang concurrency

This talk shows the intimate relationship between faults and scaling.

We argue that systems that are designed for fault-tolerance will be easy to scale. Achieving fault-tolerance requires things like non-shared memory, which as a side effect makes them easy to scale.

We discuss the history of fault-tolerant systems and define six underlying principle that any system must have in order to achieve a reasonable measure of fault tolerance.

We show how these six principles are implemented in Erlang.
