The document discusses using Erlang, Erlang Driver Toolkit (EDTK), and Berkeley DB (BDB) to build disruptive internet services. Erlang is a programming language designed for building highly concurrent and reliable systems. EDTK allows Erlang to interface with external libraries like BDB in a way that meshes with Erlang's concurrency model. This talk argues that combining these technologies allows building internet services with better performance, reliability, and scalability compared to traditional approaches.
