This deep dive covers Erlang/OTP 27 with string interpolation and persistent_term improvements, the OTP 28 preview, Cowboy 3 HTTP server, the pure-Elixir Bandit, the RabbitMQ-built Khepri (a Raft-based Mnesia successor), partisan as an alternative to distributed Erlang, Nerves for embedded and AtomVM for ESP32, the statically-typed gleam language and its Lustre web framework, and how WhatsApp, Klarna, Discord, Riot, Cisco, and Akamai actually use BEAM in production.

Erlang/OTP 27의 문자열 보간과 persistent_term 개선, OTP 28 preview, Cowboy 3 HTTP 서버, 순수 Elixir인 Bandit, RabbitMQ 팀이 만든 Mnesia 후속 Khepri와 Raft 합의, 분산 Erlang 대안 partisan, IoT용 Nerves와 ESP32에서 도는 AtomVM, 정적 타입 BEAM 언어 gleam과 Lustre 웹 프레임워크, WhatsApp/Klarna/Discord/Riot/Cisco/Akamai의 실제 사용까지. BEAM 생태계의 2026년 전체 지도.
