How to Design an AI Agent That Survives Infrastructure Changes

Short summary

AI agents fail during infrastructure migrations because identity tied to network addresses or API keys changes when hosts restart or regions migrate. Solution: use Ed25519 keypairs as persistent agent identifiers, stored separately, following SSH's host verification model. This pattern eliminates credential rotation, allows peer recognition after restarts, and separates identity from routing—scaling TCP/IP's architectural principle.

• •Agent identity based on IP/hostname/API keys breaks during infrastructure migrations and cloud region changes
• •Ed25519 keypairs provide persistent identity surviving restarts, eliminating manual credential rotation
• •Implementation: generate keypair once, store persistently, use public key as canonical identifier, decouple discovery from identity

Generated with AI, which can make mistakes.
