| Purpose | AWS FIS runs fault injection experiments on AWS workloads to help teams improve application performance, observability, and resilience. | FaultMesh injects controlled failures, detects anomalies in real time, remediates automatically and scores system resilience on a Kubernetes-native platform. |
| Safety controls | Experiments can use tags to select targets and CloudWatch alarms or other tools to stop an experiment when conditions are met. | Experiments support dry runs, blast-radius limits, an error-budget gate, timeout monitoring and an organisation-wide kill switch. |

FaultMesh
FaultMesh is a Kubernetes-native platform for testing system resilience through controlled failures, anomaly detection and automatic remediation. It injects latency, packet loss, pod kills, CPU stress and memory stress using Chaos Mesh CRDs. Real-time metric analysis can surface regressions, while rules and actions can heal systems automatically. The platform scores services across six dimensions and assigns L1–L5 maturity levels. It tracks SLO error budgets and supports multi-step chaos game days with checks between steps. Safety controls include blast-radius limits, dry runs, an error-budget gate, a background monitor and an instant kill switch. Teams can use managed SaaS or deploy a Kubernetes Operator in their own cluster, where data stays inside their perimeter. Security features include JWT and API-key authentication, role-based Admin, Operator and Viewer access, encryption in transit and an immutable audit trail. The maker describes controls as SOC 2-aligned, with formal certification on the roadmap, and data handling as GDPR-aligned. Starter is free for up to three services; Growth costs $49 a month billed per host, and a 14-day trial is available.
