Infrastructure

We run the metal, or you do.

Velone is infrastructure, not a wrapper on someone else's API. We operate Firecracker hosts across eight regions, and the same build runs inside your own account when that is what compliance requires.

shared kernels

One guest kernel per session.

01 / the substrate

Hardware isolation, warm pools, real capacity planning.

Hypervisor
Firecracker microVMs on bare metal. One guest kernel per session, jailer-confined, with a minimal device surface and seccomp filters on the host side.
Hosts
AMD EPYC and Graviton classes, NVMe local storage, 25Gbps networking. No oversubscription of vCPU on production pools.
Pools
Warm pools per region and per runtime keep booted VMs waiting. Pool depth autoscales on demand and can be pinned if your latency budget is strict.
Snapshots
Full memory and disk snapshots to local NVMe, then to object storage. Restore of a suspended session is typically under a second.
GPU
L4 and A10G pools on request for agents running local inference. Same isolation model, scheduled separately.
Control plane
Regional, stateless in front of a replicated store. Policy is cached at the host so a control-plane partition fails closed rather than open.
Networking
Per-session virtual interfaces with no route to each other. All egress traverses the gateway; there is no direct path out of a sandbox.
Storage
Workspace volumes encrypted at rest with per-session keys. Disks are zeroed on teardown and never reused across tenants.

Data residency is a region property, not a best effort. A session pinned to eu-central never schedules, snapshots, or logs outside the EU.

03 / deployment

Three ways to run it.

The same build ships in all three. There is no cut-down self-hosted edition with the interesting features removed.

managed

Velone Cloud

Our hosts, our regions, our on-call. The fastest way to a governed agent, and where most teams start.

byoc

Your cloud account

Data plane in your AWS, GCP, or Azure account. We operate the control plane; workload data and egress never leave your perimeter.

air-gapped

Your metal

Fully disconnected install for regulated estates. Signed release bundles, offline licence, no phone-home.

04 / how we measure

The numbers, and what they mean.

Latency claims are worthless without a definition, so here is ours.

cold start (warm pool)   p50  148ms   p95  212ms   p99  340ms
  measured from POST /sessions to a shell accepting input

cold start (cold host)   p50  870ms   p95  1.2s    p99  1.9s
  includes host selection and VM boot, no pool available

policy decision          p50  1.1ms   p95  3.4ms   p99  6.2ms
  in-process at the host, cached policy, excludes escalation

snapshot / restore       p50  610ms   p95  940ms
  4GB working set to local NVMe

evidence append          p50  0.8ms   p95  2.1ms
  local durable write, async replication to your store

05 / questions

Are you reselling E2B or Modal?

No. We operate our own Firecracker fleet on bare metal, because the binding between the VM, the identity, and the policy has to happen below the API for the guarantees to mean anything. We will still run on top of a sandbox vendor if you already have a contract and want us to.

What happens if the control plane goes down?

Running sessions continue with cached policy. New privileged actions that require an escalation fail closed. Sessions that need a policy refresh stop rather than proceed on stale rules.

Can we bring our own hardware?

Yes, for BYOC and air-gapped installs. The requirement is nested-virtualisation-capable hosts, or bare metal, plus an object store and a Postgres-compatible database.

Do you support Kubernetes?

The control plane runs on Kubernetes happily. The data plane deliberately does not run agent workloads in pods, because a shared kernel undermines the isolation claim. Hosts join the fleet as VM hypervisors instead.
