VM to Container Migration

Still paying for idle virtual machines?

Most VM fleets run far below capacity — you pay for the peaks and idle through the rest. Containers change the economics: higher density, faster recovery, smaller attack surface. We get you there without downtime.

Why migrate

Three returns from one move

Lower cost

Containers pack far more workloads onto the same hardware. No full OS per app, no idle capacity billed around the clock — most estates shrink significantly after migration.

Better performance

Containers start in seconds, not minutes. Failures recover automatically, deployments roll out with zero downtime, and scaling reacts to traffic instead of waiting on new VMs.

Tighter security

Minimal images carry a fraction of a VM's attack surface. Patching means rebuilding an image, not maintaining fleets of operating systems — and every workload runs isolated.

How it works

A phased path — never a big-bang cutover

  1. 1

    Assess

    Two weeks: we map your workloads and produce a roadmap, cost model and risk analysis.

  2. 2

    Containerise

    We containerise service by service, starting with the lowest-risk workloads.

  3. 3

    Cut over

    New environment runs alongside the old, verified under real traffic — with rollback ready.

  4. 4

    Operate

    Monitoring, autoscaling and CI/CD from day one — or a full handover to your team.

Case study

We run what we sell

Every J2DK system — including this website — runs fully containerised on the same architecture we migrate clients to. This site ships as a 22 MB hardened image: it runs as a non-root user on a read-only filesystem with every Linux capability dropped, behind a strict Content-Security-Policy.

In our first week we shipped fourteen releases — each one an immutable, versioned image, deployed with zero downtime and a one-command rollback. That's the operating model a migration buys you.

  • ~1 sContainer startup — instant recovery & rollback

The fixed-price migration assessment

Before you commit to anything, know exactly what you're getting into. In two weeks, for a fixed price, we analyse your current estate and hand you a decision-ready plan — yours to keep whoever does the migration.

FAQ

Common questions

Will there be downtime?

No. We run the containerised environment alongside your existing VMs, verify it under real traffic, and switch over gradually — with a tested rollback plan at every step.

How long does it take?

The assessment takes two weeks. A typical migration runs from a few weeks for a handful of services to a few months for larger estates — you'll have an exact timeline before you commit.

Do we need Kubernetes?

Not always. For smaller workloads, plain Docker or a managed container service is often the right answer. When Kubernetes is the right fit, we support it anywhere — managed cloud (EKS, AKS, OKE) or on-prem on your own hardware.

What about databases?

Stateful systems need special care and sometimes stay where they are — often a managed database service is the better move. The assessment maps each one and recommends the safest path.
