Isolation Isolation technology the vendor states for each sandbox.
pluggable (gVisor/Kata) (source: kubernetes-sigs/agent-sandbox (GitHub))
Other isolation options Alternative runtimes the vendor offers besides the default (e.g. VM runtime, gVisor for GPU).
Not published
Deployment Managed cloud service, self-hosted software, or both.

Billing basis What the meter counts: wall-clock allocated resources, active CPU only, requests/plan quota, session-hours, or free software.
free (OSS) (source: kubernetes-sigs/agent-sandbox (GitHub))
vCPU price $/vCPU-hr Published on-demand CPU rate normalised to USD per vCPU-hour (per-second rates multiplied by 3,600; per-core rates divided by vCPUs per core where the vendor defines it). Lowest public tier, default region.
$0.00 (source: kubernetes-sigs/agent-sandbox (GitHub))
Memory price $/GiB-hr Published memory rate normalised to USD per GiB-hour (GB treated as GiB where the vendor does not distinguish). 0 means the vendor states memory is free.
