Multi-Variant Comparison

Comparative Simulation

Run the same base parameters against multiple architecture variants simultaneously. Compare time-series curves, aggregated metric peaks, and stress states side-by-side.

Rankings are deterministic. Same input always produces identical output.

Simulation Engine

Variants(3 of 6)

Each variant inherits the base parameters for this engine. Override specific parameters per variant to isolate what changes.

How it works: Configure 2–6 variants. Each inherits the base parameters for the selected engine and applies its overrides on top. The engine runs each variant independently with deterministic formulas, then ranks them by metric peaks and risk level.

Metric rankings identify which variant wins each dimension (e.g., lowest P95 latency, lowest connection utilization). Time-series overlays show how each variant's trajectory differs step-by-step.
