Migrating a Warehouse Application from C# to Elixir
summary
Warehouse app moves from C# to Elixir by rewriting service components incrementally and running Elixir and C# versions side‑by‑side on the same server to compare latency and throughput. Results show much lower request latency, fewer long poll timeouts, and faster processing for sensor-heavy workflows; isolated BEAM processes plus supervisors give automatic recovery instead of retry storms. Migration starts with one service, teaches the team Elixir, supports 200 active users now and a 5,000‑user target, and scales without expensive cloud rearchitecture.
