Foundation 2.0: Libcluster-Partisan Battle Plan

Executive Summary

Foundation 2.0 combines the best of both worlds: deep BEAM primitives for local concurrency excellence with Partisan-powered distribution that obsoletes libcluster. This unified approach creates the first framework that’s both BEAM-native and enterprise-distributed, positioning Foundation as the definitive platform for next-generation distributed BEAM applications.
