Air-Gapped DoD IL5/IL6 Observability Platform
GateScale architected a production hub-and-spoke LGTM observability platform (Mimir, Loki, Tempo, Grafana and Alloy) across multiple air-gapped EKS clusters on AWS GovCloud for a geospatial tactical simulation program. We enforced NIST 800-53 Rev 5, FedRAMP High and DISA STIG end-to-end, sourced 100% of Helm charts from DoD Iron Bank / Big Bang, secured ingress with Istio mTLS and Transit Gateway private DNS, deployed SAML-federated CAC/PIV authentication via Keycloak, and stood up a cATO telemetry foundation delivering continuous, audit-ready evidence streams.
