One difference is that Erlang&#x27;s concurrency and error handling in the language is more basic than Akka&#x27;s and does not directly provide fault-tolerance through supervision but does provide the primitives to implement. All of OTP is implemented in Erlang with these basic primitives. These primitives are actually very simple, the difficulty was getting the right set of simple primitives on which to build the rest.<p>Also I think you will find that a lot of features which are very similar of Akka&#x27;s location transparency were built-in to the distribution mechanisms which are part of Erlang. We were at least thinking of distribution from a very early stage.
