Cloud Solutions

Private and public cloud, designed around your workloads

We design, build and run the platform underneath your applications — choosing the technology to fit each workload rather than a vendor’s licensing model.

Deployment models

Three ways to run

Most estates end up using all three. The question is which workload goes where — and what it costs you to change your mind later.

Infrastructure you govern

Dedicated capacity on-premises or in a hosted facility, built on OpenStack for infrastructure and OpenShift for applications. You decide where data sits and who can reach it.

Best for

  • Data that cannot leave a jurisdiction or a compliance boundary
  • Steady, predictable load where owning capacity beats renting it
  • Environments an auditor needs to see end to end

Scope

What we take responsibility for

A platform is more than the compute underneath it. These are the pieces that come with every environment we build, whether you run it afterwards or we do.
  • Architecture & buildReference design, landing zones and deployment — delivered as Terraform and Ansible you keep.
  • MigrationMoving existing workloads with a rollback path, not a big-bang cutover.
  • Security & complianceHardening, policy and the evidence trail an audit will ask for.
  • Identity & networkingOne set of credentials and one routable network across every environment.
  • Observability & costPrometheus-based monitoring, plus the tagging and showback that keeps spend attributable.
  • Backup & disaster recoveryTested recovery targets — not a backup job nobody has ever restored.

A closer look

What hybrid actually looks like

Almost every hybrid estate has the same shape: data that has to stay where it is, applications that have to move quickly, and one delivery pipeline that shouldn’t care which side it is deploying to.
  • Data with residency or compliance constraints stays in the private cloud
  • Customer-facing and unpredictable workloads run in public cloud
  • One identity, one network and one deployment target span both

Placement becomes a decision you can revisit — not a commitment you’re stuck with.

How we work

Four steps, no surprises

  1. Discover

    We map workloads, compliance constraints and current spend, and tell you which of them actually justify a change.

    2–4 weeks

  2. Design

    An architecture you can read — placement per workload, the security and network model, and what it will cost to run.

    Reviewed with your team

  3. Build & migrate

    Deployed as versioned configuration, migrated in waves, each with a rollback path.

    Delivered in increments

  4. Operate or hand over

    Monitoring, patching, right-sizing and DR drills — or a documented handover to your engineers.

    Your call

Common starting points

Sound familiar?

We size what a private cloud on OpenStack would actually cost to build and run against that renewal, including the operational effort, and tell you plainly if the maths doesn’t work. Sometimes it doesn’t.
Usually a tagging and right-sizing problem before it’s an architecture problem. We start with where the money is going, then look at whether any of those workloads belong somewhere else.
A private cloud in a facility you or your provider control, with the identity, network and audit trail built to be shown to a regulator rather than explained to one.
We map what’s running where, then put one identity, network and deployment model across it — so the estate becomes deliberate without having to be rebuilt.

Why NubeStack

Why teams bring us in

  1. No vendor allegiance

    We have no licences to sell, so the recommendation is simply whatever fits your workloads — including the option of changing nothing.

  2. We can stay past go-live

    We run platforms as well as build them, which tends to show in how they’re built and what we’re willing to hand over.

  3. Your engineers own it

    They’re in the design sessions from day one, because they’re the ones who’ll be living with the result long after we’ve gone.
