- [The soul of Erlang](https://www.youtube.com/watch?v=JvBT4XBdoUE) by Sasa Juric (2019) which shows off the essence of the BEAM. <q>I think it might actually be _easier_ to inspect the BEAM over those other VMs. For one, it is much older and stable. And secondly, the BEAM has a lot of self-introspection features.</q> -- [via](https://news.ycombinator.com/item?id=38184807)

## Scalability

- [How scalable is Erlang?](https://www.quora.com/Just-how-scalable-is-the-Erlang-VM/answer/Ulf-Wiger?srid=557Y&share=1), quora answer by Ulf Winger. [Aug 2015]

## Books / Learning Resouces

- [Spawned Shelter - the best articles, videos and books for learning Erlang, the internals of its virtual machine and other languages that run on top of it](http://spawnedshelter.com/)

- [happi/theBeamBook: A description of the Erlang Runtime System ERTS and the virtual Machine BEAM.](https://github.com/happi/theBeamBook)
- [Adopting Erlang](https://adoptingerlang.org/) is an ongoing effort to gather all the resources that will help you use Erlang in a business. The booksite is divided in three sections focusing particularly on Erlang/OTP’s higher level concepts in the current open source ecosystem, how to use it in production (while setting up a pipeline for continuous development and delivery), and how to build a team when you’re starting from scratch.
