## Kubernetes Traffic Replay: Test with Real Production Patterns

*   No manual test script creation required
    
*   Automatically handle dynamic data and state
    
*   Validate complex user journeys and edge cases

## How Kubernetes Traffic Replay Works

### 1\. Observe

Speedscale captures Traffic Context through a variety of means such as sidecars, Postman collections, or even on your local desktop. Data is sanitized for security, so no sensitive data is used.

### 2\. Transform

Speedscale then intelligently parameterizes key fields such as timestamps, unique IDs, and customer/order IDs in order to replace them with realtime values during traffic replay for flexible, no-code reuse.

### 3\. Replay

Collected Traffic Context can be browsed, filtered and selected in the Traffic Viewer to auto-generate tests and mocks from. Replay at scale to validate performance and functionality.

## Kubernetes-Native Features

### Sidecar Deployment

Deploy as sidecar containers to capture traffic without modifying your applications.

### Data Sanitization

Automatically redact sensitive data and PII while preserving traffic patterns.

### Smart Parameterization

Intelligently replace timestamps, IDs, and dynamic values for realistic replay.

### Service Mesh Support

Works with Istio, Linkerd, and other service mesh technologies.

### Load Testing

Scale captured traffic to test performance under realistic load conditions.

### Environment Isolation

Replay traffic in development, staging, or test environments safely.
