InfraSim simulates infra failures without touching production. Unlike Gremlin or Chaos Monkey, InfraSim runs 150+ chaos scenarios in memory — proving your system's theoretical availability ceiling. Key features: - 5 simulation engines (Static, Dynamic, Ops, What-If, Capacity) - 3-Layer Availability Limit Model (4.00 to 6.65 nines) - AI-powered analysis with remediation recommendations - DORA compliance report generation - Terraform/Prometheus integration - Plugin system for custom scenarios
