Do You Really Need Processes? - Exploring Performance and Resiliency in BEAM Applications

Explore the necessity of processes in BEAM applications through a conference talk delivered at Code BEAM Europe 2023. Dive into a demonstration of a ride-sharing application created to showcase the capabilities of a standard Phoenix and PostgreSQL setup. Examine the potential performance and resiliency gains achievable through various process and supervision architectures, including external databases, process state, ETS tables, and hybrid approaches. Gain insights into when and how to effectively implement GenServers and Supervisors to optimize your application's performance. Challenge assumptions about the ubiquitous need for processes in BEAM-based systems and learn to make informed decisions about architectural choices for your projects.
