Choosing the right isolation tier depends on code trust, tenancy, and compliance.
Firecracker micro-VMs let agents install packages safely without idle compute costs.
Disk format matters less than how snapshots capture, index, and restore agent state.
Idle time dominates agent costs, and how platforms bill it determines deployment economics.
Firecracker isolates AI agent code with VM-level security at container economics.
Agents need memory systems that track truth and relationships, not just retrieve similarity.
Multiple infrastructure layers compound cold start delays before agents produce any output.
