unStack is a cloud where every server is physically yours.
We run the Kubernetes; you get whole machines — no hypervisor, no noisy neighbours, no surprise bill.
Back then apps were CPU-bound and distributed systems barely existed, so mutualising a few big servers with a hypervisor made sense.
That trade-off is now baked into your bill — and it no longer holds.
Only the services that actually matter: Kubernetes delivered on hardware you don't share with anyone and S3.
Fully managed K8s clusters on dedicated microservers — no virtualization. Deterministic performance, hardware isolation, an immutable hardened Linux built for one job.
Bare-metal at the price of a VM, each dedicated to one client, only 5–30 watts.
Multi-tenant cloud services are replaced by Kubernetes operators installed right inside your own cluster. We manage them for a familiar experience — you keep full control. The ecosystem is open; you pick your level.
Standard Simple Storage Service hosted and managed outside your cluster by unStack on a dedicated infrastructure.
Kubernetes already gives you the resilience the hypervisor was invented for.
So we removed everything in between — three whole layers of overhead.
50–70% of cloud workloads are database-backed apps — ERP, CRM, HR, collaboration, custom LOB tools.
They're I/O-bound. In a traditional cloud the disk is a network hop away — remote block storage, behind the hypervisor. On unStack the NVMe lives inside the machine, direct-attached, so you get its native throughput instead of a throttled fraction of it.
And IOPS aren't even the whole story — latency is what kills you. A database query is thousands of small, sequential I/Os: at 10 ms each, your app spends its life waiting. Direct NVMe answers in ~0.1 ms.
Customers used to pay a fortune for catastrophic performance — most never realized it, because there was no alternative.
// until now.
On unStack a cluster isn't pinned to one availability zone. By default it spans two AZs, ~400 km apart (to protect against natural disasters).
A Kubernetes control plane keeps quorum across both — so an entire AZ can go dark and your cluster keeps serving.
It's the default shape of every cluster, not a disaster-recovery bolt-on.
A microserver draws 5–30 watts, powered over Ethernet — a lightbulb, not a radiator. A virtualized rack server pulls hundreds of watts before your first request is served.
Unstacking is itself an energy plan: the hypervisor and host OS burned watts on bookkeeping, and overallocation kept oversized machines idling at full power. Remove the layers, and that tax disappears with them.

Migrating to unStack is a project — we run it with you. Our engineers audit your current setup, plan the move and execute it by your side, then keep your cloud spend under control.
