Reliability in distributed systems is largely determined by early architectural decisions, not post-launch fixes. Choices around service boundaries, coupling, deployment models, and observability compound over time and become business-critical at scale. Research shows ~70% of outages stem from configuration changes, not hardware failures, and downtime can cost enterprises over $300K per hour. The post argues resilience must be designed in from the start, not retrofitted, and briefly highlights Elixir/BEAM as a technology built around fault tolerance and process isolation.
