Connect to SageMaker Managed MLflow (mlflow-app or mlflow-tracking-server ARN) as an MLflow backend, then hand off to the other MLflow skills. Triggers on a SageMaker MLflow ARN (arn:aws:sagemaker:...:mlflow-app/... or arn:aws:sagemaker:...:mlflow-tracking-server/...) or "SageMaker Managed MLflow".
This skill should be used when the user asks "how does this scale", "scale to millions", "scaling roadmap", "where is the bottleneck", "what breaks first", "10x growth", "vertical vs horizontal scaling", "scale from zero", or "what's the next scale curve". It gives the order-of-magnitude evolution path (single server → tiers → replicas → cache → CDN → stateless tier → multi-region → sharding) and a way to diagnose the *next* bottleneck instead of memorizing one big diagram. Use it whenever a design must grow by orders of magnitude or a load increase is on the table, even if the user doesn't say "scaling".
Use when polypainting in ZBrush (skin color zones, fills, cavity or AO passes, Spotlight), baking polypaint to a texture or vertex color, rendering a ZBrush model with BPR or Redshift, making render passes, a turntable or portfolio shots, or when paint looks like uniform beige or clown makeup, is blurry, is hidden under a texture or in Redshift, or a render is noisy, clipped, orthographic or bruised.
