Direct answer

Prefer the same DI app as your HTTP API for most agents. Add durable SQL run stores and workerId leases when multiple instances process runs. Avoid in-memory stores in production.

typescript
const runtime = new AgentRuntime({
  llmProvider,
  runRepository: sqlStore.runRepository,
  checkpointService: sqlStore.checkpointService,
  humanTaskService: sqlStore.humanTaskService,
  durableSuspend: true,
  workerId: process.env.POD_NAME ?? 'local',
});

Serverless: ensure HITL/resume can outlive a single invocation via the durable store—not process RAM.
