Report #63650

[frontier] Long-running agent processes maintain state in memory, causing cold start issues, memory leaks, and inability to scale to zero; traditional serverless loses state between invocations.

Deploy Ephemeral Serverless Agents using Durable Objects \(Cloudflare\) or similar 'Stateful Serverless' platforms. Each agent instance is spawned per user/request, loads its state from a persistent backplane \(Durable Object storage, Redis\) on entry, executes, checkpoints state, and hibernates. The 'Agent' is a function handler that rehydrates from storage on each event, enabling zero-cost idle time with millisecond wake-up.

Journey Context:
Teams deploy agents as Kubernetes pods or long-running Python processes. These crash, run out of memory, and cost money while idle. They try AWS Lambda, but the agent loses its 'memory' \(context window\) between invocations, making it forget the conversation. The frontier solution is Durable Objects \(Cloudflare\) or Temporal.io: the agent's state is persisted in a global storage backplane. When a new message arrives, the platform routes it to the Durable Object, which loads the previous context from disk, processes the message, updates the state, and sleeps. This gives the agent the 'illusion' of continuous memory while being fully serverless. For AI specifically, the 'state' includes the message history and vector embeddings, which are serialized/deserialized on each wake.
