About Eric Merritt

Co-author of Erlang and OTP in Action, open source contributor, Erlang Engineer.

James Aimonetti of 2600hz.com will be joining us tonight to talk about how Erlang powers the Kazoo project and Voice-over-IP products all around the world.

Kazoo is a scalable, distributed, cloud-based telephony platform that allows you to build powerful telephony applications with a rich set of APIs.

Designed to handle anything from large carrier to small countries, the Kazoo infrastructure can do it all. There are no lock-ins and the software is open-source to give you complete freedom.

James will be giving us a high level view of the architecture behind Kazoo, both from a platform perspective and from an Erlang perspective. We'll survey some of the code that is of interest, such as the gen_listener behaviour (for AMQP message consumption), the PropEr tests in various modules, the wh_json module for working with Erlang-encoded JSON objects), and more. No telecom experience required!

Have you heard of Phoenix? Phoenix is a framework for building HTML5 apps, API backends and distributed systems. Written in Elixir.

Seve Salazar of HouseHappy.org will walk us through creating a simple but real(wish)-world JSON API using Phoenix and deploying it to production as an OTP application. It will cover usage of Ecto, rendering JSON from a controller, integrating with StatsD using Exometer, and finally using edeliver to ship it to production.
