[erlang-questions] SOA with Erlang

I should clarify my rather oblique argument than OTP is SOA.

OTP very cleanly supports the notice of publishing and consuming services in the form of local and global gen_servers.  One Erlang node may run a gen_server that provides session data, while another runs one that provides inventory information and yet another runs Zotonic (or something similar) to render a web-based UI.  

The beauty of Erlang/OTP is that all these services can transparently be on a single node or any number of nodes.  Even better is that Erlang/OTP makes deciding how failures are handled and communicated manageable and clean.

Start simple and gradually.  This mailing list is a treasure trove of design patterns and best practices.  Ask single focused questions about what you are looking for and you will get great and timely responses :)

Erlang/OTP makes SOA easy.

I hope you have as much fun applying it as I do :)
