Spike Testing

Sudden traffic surges from flash sales, viral events, or marketing campaigns. Validates autoscaling reaction time, cold-start behavior, and graceful degradation.

Key Features

  • Instant traffic step from baseline to 5×–20× expected peak
  • Autoscaling reaction time measurement (HPA, ASG, serverless cold starts)
  • Queue depth, dropped-request rate, and backpressure validation
  • CDN, WAF, and rate-limiter behavior under burst
  • Graceful degradation paths: circuit breakers, fallbacks, queueing
  • Recovery timeline once the spike subsides

About This Service

Spike Testing simulates the moments your infrastructure was not designed for but absolutely needs to survive: a flash sale launch, a viral post driving 20× normal traffic in under a minute, a product mention from a major publication. Sevarity steps traffic from baseline to multiples of expected peak instantly and measures how quickly autoscaling reacts, whether circuit breakers fire correctly, and which requests get dropped versus queued. The deliverable is a clear picture of your real elasticity, not your theoretical one.
