Platform lock-in in regulated environments (financial services, betting, streaming) is primarily an architectural risk, not just a procurement concern. When infrastructure tightly couples to provider-specific services for messaging, orchestration, or state management, systems lose flexibility precisely when workloads grow or regulations change. Long-running distributed systems face the sharpest exposure during traffic spikes. Key mitigation patterns include decoupling application logic from infrastructure, using open protocols over proprietary messaging, distributed state management, and horizontal scaling. Elixir/Erlang's process isolation and supervision model is highlighted as well-suited for high-reliability, continuously available systems that need to remain adaptable as infrastructure evolves.
