Cloud Migration

Move production systems to AWS, GCP, or Azure without planned downtime — assessment first, every cutover rehearsed.

Cloud migration

We take production systems off ageing infrastructure and onto AWS, GCP, or Azure without stopping them. Every cutover is planned, dual-run, and reversible — not a weekend gamble with a rollback engineer on standby.

What usually goes wrong

Migrations fail when someone invents the plan at 2am. No risk register, no dual-run, no rehearsal — just a cutover window and hope. We built the engagement the other way around: assessment and written risk before architecture, then a cutover you can reverse at any step.

How an engagement runs

  1. Assess — inventory, dependency graph, risk register (week one)
  2. Plan — target architecture, cutover design, rollback rehearsal, stakeholder comms
  3. Migrate — staged cutover, dual-run validation, live monitoring
  4. Verify — load and failover tests, security review, sign-off
  5. Optimise — cost tuning, runbooks, team handover (ninety days included)

Every phase ends with a decision point. You can stop at any of them.

What we hold ourselves to

  • Zero planned downtime on cutover day — dual-run first, traffic shifts gradually, rollback ready
  • Infrastructure as code — no console-built snowflakes; Terraform reviewed like application code
  • Cost after, not only before — right-sizing and continuous review, not lift-and-shift-and-forget
  • Written decision points — you get a read-back after each phase, not a black box until go-live

Most engagements end here: containerised workloads on managed Kubernetes, shipped through CI/CD, watched end to end — and cheaper to run than the estate they replaced.

FAQ

How long does a typical migration take?

Depends on size and coupling. Assessment is usually 1–2 weeks. Many estates land first workloads in 8–16 weeks from kickoff; complex multi-system programmes run longer and we phase them.

What about cost versus on-premise?

Often 30–50% lower run cost in the first year when right-sized — not guaranteed for every estate. We model it in the assessment before you commit.

Will there be downtime?

Planned downtime target is zero for cutover. We dual-run, rehearse traffic shift, and keep rollback ready. If a workload cannot meet that, we say so in writing before we start.
