Joe Armstrong explains through Erlang examples that message passage concurrency represents the foundation of scalable fault-tolerant systems. Some of his presentation’s nuggets are: using the wrong abstractions makes life artificially difficult; it’s not about objects, it’s about messages; no shared memory; messages enforce isolation if communication is asynchronous; it’s all about protocols.
Joe Armstrong is the principal inventor of Erlang and coined the term "Concurrency Oriented Programming". At Ericsson he developed Erlang and was chief architect of the Erlang/OTP system. In 1998 he formed Bluetail, which developed all its products in Erlang. In 2003 he obtain his PhD from the Royal Institute of Technology, Stockholm. He is author of the book "Software for a concurrent world".
