Scott Lystig Fritchie presents the architecture and lessons learned implementing a webmail system in Erlang, using UBF and Hibari, a distributed key-value store, to accommodate a large user base.
Steve Vinoski talks about the media distribution market and how Erlang is used in a media distribution switch to control the video stream flow at speeds up to 200Gb/s and handling tens of thousands of open HTTP connections.
Joe Williams discusses how distributed systems, cloud computing and automated configuration management affect system’s availability. He exemplifies with a database service built on CouchDB, Erlang, Chef, all running on EC2.
Cliff Moon explains how to make Erlang programs faster by writing performance critical sections of the code in C using Native Implemented Function and by integrating libraries using the linked-in driver interface. He also shows how to safely use C drivers in the Erlang concurrent environment and how to debug them in a running VM.
Sadek Drobi talks about abstracting the control syntax (glue), giving examples from mainstream and FP languages: Null, propagating errors, events, asynchronous programming, lists, streams, channels, functors, monads, and custom abstractions.
Eric Merritt, Martin Logan and Richard Carlsson share their story, the challenges and lessons learned along the way as first time book authors (“Erlang and OTP in Action”) from engaging into such a project, coming up with a TOC, reviews, production, print and working with the publisher throughout all the phases.
Bjarne Däcker recounts the story of CSLab at Ericsson, the birthplace or Erlang, how it started, some of the projects leading to Erlang, and its eventual success inside Ericsson as Erlang/OTP.
