For the 3rd or 4th time in my life, I'm (re-)learning #AMQP 0.9.1, the protocol used by #RabbitMQ. I first used RabbitMQ ca. 2010-2013 to convert a monolithic application to a service architecture. It was solid as rock even back then, being written in Erlang, a functional, asynchronous, highly fault-tolerant programming language invented to run telecom infra at Ericsson (hence the name) with syntax based on Prolog (!!!).
