Syscall Shims Like gVisor Deserve a Spot in the Sandbox Isolation Landscape, Argues Engineer
sloppenheimer · x · 2026-09-24
- sloppenheimer critiques a sandbox isolation comparison chart: syscall shims like gVisor should appear, as gVisor offers the best blend of container-to-microvm performance.
- He suggests adding suspend/resume as a dimension and pushing granularity further left.
- He also argues isolation and network policy should be data managed by a controller at the platform layer (e.g., via eBPF), not baked into a high-level API.
