Semaphore is a hosted continuous integration and deployment platform that runs on 20 dedicated servers. It uses Ruby and is distributed and semi-fault tolerant. Erlang's BEAM virtual machine underlies many messaging systems and is used by WhatsApp and other apps to handle half of mobile data traffic worldwide with 99.999+% uptime. The BEAM model allows processes to communicate asynchronously through message passing and be isolated from each other for robustness.
