Serverless Hosting Plan

Data artifactInfrastructureInfrastructureVariation point (abstract)arc:ServerlessHostingPlan

An abstract configuration selecting how a serverless runtime provisions capacity for a function, trading cold-start latency and timeout limits against idle cost.

Responsibility. Fixes the capacity provisioning and billing model of a serverless function.

Also known as: Function hosting plan

Variants

Variant	When to choose
On-Demand Consumption Plan	Choose for variable, unpredictable or infrequently triggered agent workloads.
Pre-warmed Capacity Plan	Choose for latency-sensitive agents requiring consistent performance; avoid enabling it for all functions, since it pays for idle capacity and removes serverless's main cost benefit.
Reserved Capacity Plan	Choose for predictable, constant high-volume agent workloads where reserved capacity costs less than pay-per-execution billing.

Design guidance

SHOULD choose the plan per agent workload: consumption for sporadic agents, pre-warmed for latency-sensitive agents, reserved capacity for constant high-volume agents.
