Snapshots, copy-on-write, and the economics of agent sandboxes
A technical blog post breaks down how agent sandboxes can be made cheaper and faster by leaning on filesystem snapshots and copy-on-write semantics. The core idea is that when agents need isolated environments, the economics depend heavily on how much state has to be duplicated versus reused.
The post focuses on:
- snapshot-based provisioning for disposable agent environments
- copy-on-write as a way to reduce duplicate storage and startup overhead
- the trade-offs between isolation, speed, and operating cost
It is aimed at builders thinking about the infra layer behind agent execution, not at end users.
