I haven’t used it enough to be able to say yet, but I believe the BEAM avoids part of the problem Ian Cooper (Where Did It All Go Wrong?) rediscovered, which is that microservices don’t min-max the inter- versus intra-modular friction in systems. I would not say that Beam eliminates this problem in any way, but I do think it lowers the slope of the line. The self-consistent idioms and functionality, especially with deployment, auto recovery and load balancing, reduce the inter-module friction. It makes a system where 12 engineers can easily manage 30 endpoints, and your surface area can still follow a power law.
