Is this specifically an AI agent? That question comes first.
Meridian's own three-way split proves the decision, not arbitrary variety.
dispatch-api
Cloud Run
Spiky, customer-facing HTTP
route-optimizer
GKE
Needs closer runtime control
AI dispatch assistant
Agent Runtime
Multi-turn, tool-calling
If not an agent: need fine-grained node control or complex multi-container orchestration → GKE. Otherwise → Cloud Run or Cloud Run functions.
