## Resource

Episode 106 explores how Erlang and the OTP framework continue to underpin the world's most reliable telecommunication systems. Lucas and Luna break down the actor model, hot code swapping, and the 'let it crash' philosophy, using Ericsson's AXD301 as a concrete case study. They discuss why modern cloud-native platforms like WhatsApp still lean on Erlang's decades-old design for fault tolerance, and what the rise of Elixir means for the ecosystem. A deep dive into the language that delivers nine nines of reliability. #Erlang #OTP #Telecom #Ericsson #WhatsApp #ActorModel #FaultTolerance #HotCodeSwapping #LetItCrash #Concurrency #Elixir #BEAM #DistributedSystems #Reliability #NineNines #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
