Building Distributed Systems with Riak Core by Steve Vinoski (Basho).
From the description:
Riak Core is the distributed systems foundation for the Riak distributed database and the Riak Search full-text indexing system. Riak Core provides a proven architecture and key functionality required to quickly build scalable, distributed applications. This talk will cover the origins of Riak Core, the abstractions and functionality it provides, and some guidance on building distributed systems.
Rest assured or be forewarned that there is no Erlang code in this presentation.
For all that, it is still a very informative presentation on building scalable, distributed applications.
