This is a sketch of a microservice architecture using Elixir, Redis, HAProxy, and docker-compose. It showcases a kind of command/query responsibility separation, a load-balanced web API, and clustered queue-workers that are capable of message-passing amongst themselves.
Elixir and Erlang have an interesting execution module. You program using processes and message passing, but they abstract this into the concept of servers. You call a function (typically GenServer.call(pid, args)) and this in turn send a message to the server identified by pid. Inside that server, you write callback functions that are invoked in response to these messages.
Like others who have followed Elixir's progress and adoption over the past several years, we love that Elixir has put the concurrency capabilities of Erlang within reach of the common developer, making it easy to crank out solid functionality that handles intense usage environments and traffic spikes.
Glayu is a static site generator for mid-sized sites that generate content frequently and have to deal with multiple categories, like magazines and newspapers.
