Scale

Express capacity ranges and metrics for components and systems.

Scale

Use scale to capture expected capacity, concurrency, or throughput ranges.

Syntax

import { * } from 'sruja.ai/stdlib'


App = system "App" {
  API = container "API" {
    scale {
      metric "req/s"
      min 200
      max 2000
    }
  }
}

view index {
include *
}

Guidance

Choose a single clear metric per block (e.g., req/s, users, messages/s).
Use realistic bounds to guide design and SLOs.
Pair with slo and requirements to encode targets.

slo for availability/latency/errorRate/throughput targets
requirements for performance expectations
