INSIGHT

Kubernetes Is Mainstream, Not Simple

  • Kubernetes is mainstream but operational complexity remains, especially around app behavior in production.
  • Speedscale targets the app testing gap by replaying real production traffic in non-prod clusters.
ADVICE

Replay Production Traffic Pre-Deployment

  • Replay real production traffic in pre-prod to reproduce realistic mixes of calls and headers.
  • Use traffic replay to surface scaling and integration issues before they hit production.
ADVICE

Mock External Services To Enable Safe Tests

  • Mock third-party APIs so tests run without hitting live services or incurring side effects.
  • Capture real production interactions to generate repeatable integration tests for CI.
