Explore the principles of building large-scale, self-healing, and scalable systems in this conference talk from Strange Loop 2013. Delve into architectural concepts for creating fault-tolerant systems using small, isolated parallel components that communicate through well-defined protocols. Learn about detecting and correcting runtime errors, evolving programs while they're running, and the role of Erlang in implementing these principles. Gain insights from Joe Armstrong, one of Erlang's inventors, as he shares his expertise in constructing robust distributed systems. Discover key topics such as highly available data, replication strategies, isolation for concurrency, fail-fast approaches, and fault tolerance implications for scalability. Understand how these concepts apply to real-world projects and the challenges of distributed programming.
