The Compounding Platform Tax
Security controls rarely break a banking platform alone. Their cumulative divergence from Kubernetes standards creates a compounding maintenance tax.

Application Level Dependency Chaos Testing
A scoped chaos rule takes one dependency down and nothing else, so the fallback branch in your code executes on demand instead of during an outage.
Reliability Engineering in the AI Era
See why reliability engineering must span code, testing, telemetry, and incidents as AI agents erase the boundary between pre-production and production.
From Telemetry to Traffic
Compare eBPF, sidecars, telemetry agents, OpenTelemetry, APM, and proxies through an evolving ladder of production visibility.
Chaos Monkey Won't Find Your Bug
Infrastructure and application chaos break different layers and find different bugs. Netflix built two systems for a reason. Most enterprises buy just one.
Explain Non-CPU Latency With Prometheus + proxymock
Diagnose a p95 latency regression that CPU profiling cannot explain using Prometheus histograms, then prove the fix with identical proxymock replays.
Reproduce A Rare Retry Path With Loki + proxymock
Find the rare payload that sends a service down a retry path, correlate it to the recorded response, and prove the fix with proxymock replay.
Separate Application Latency From Network Failure With Hubble
Use Cilium Hubble flow evidence and proxymock replay to prove whether a Kubernetes timeout came from your code, a dependency, or a dropped packet.
Observe Opaque Services With OpenTelemetry eBPF + proxymock
Discover endpoints, RED metrics, and traces in an opaque Kubernetes service with OpenTelemetry eBPF Instrumentation, then replay traffic with proxymock.
