Presentation: "Styling your Architecture in an Evolving Concurrent World"

Time: Monday 13:30 - 14:30

Location: Lille Sal


Erlang/OTP has been used for well over 15 years to develop distributed, fault-tolerant soft-realtime systems which run for years with no downtime. Hardware and operating systems have evolved as well as the Erlang Virtual Machine itself. This has enabled a continual evolvement of the architectures of the Erlang based application systems. The first Erlang systems were built using an active-standby architecture. When Erlang’s distributed Mnesia database allowed data to be easily replicated in a cluster of nodes, architectures where data was fully replicated became popular. As processing power and the load these systems were subjected to increased, duplicating all data was no longer viable; shared all architecture models gave way to minimal shared data and no shared data architectures. In the last few years, cloud computing has taken over, with Erlang powering its backbone and infrastructure.

This talk will look at the most common architecture patterns in Erlang-based products, describing how each of them solves a particular problem while guaranteeing no single points of failure. It will start with the early versions of the AXD301 switch and end with examples of the use of Erlang in cloud computing architectures.

 Francesco  Cesarini

Francesco Cesarini is the founder and Technical Director of Erlang Training and Consulting. He is also a co-author of Erlang Programming, a book published by O'Reilly Media. Having started his career as an intern at Ericsson's computer science lab, the birth place of Erlang, and has used the language on a daily basis for the last 15 years. He has worked with flagship Erlang projects both within and outside of Ericsson, including the R1 release of the OTP middleware and the AXD301 Switch. He has taught Erlang/OTP to hundreds of professionals and undergraduate students alike.

Soon after Erlang was released as Open Source, he founded Erlang Training and Consulting. With offices in the UK, Sweden, Poland (and soon the US), they have become the world leaders in Erlang based consulting, contracting, support, training and systems development. Their client base is spread on five continents and ranges from small start-ups to blue chip companies. In his role as Technical Director, he is currently leading the research, development and consulting teams.

He is active in the Erlang community not only through regularly talks, seminars and tutorials at conferences worldwide, but also through his involvement in international research projects. He organises local Erlang user groups and with the help of his colleagues and runs the Trapexit Erlang community website.
