What it is

What you're actually getting.

Cloud migration is rarely a technical problem; it's a sequencing problem. We design and execute migrations that ship working slices weekly so the org sees progress and the rollback path stays open.

Who it's for

Is this the right fit for you?

This is a good fit when…

  • Your data center contract is up and the timeline is unforgiving.
  • Previous lift-and-shift attempts produced cloud bills 3× the on-prem cost.
  • You're locked into legacy databases or monoliths that don't move easily.

You probably don't need this yet if…

  • Your systems already run well in the cloud.
  • You're early enough to simply build cloud-first from the start.

How it works

A clear path from first call to launch.

  1. Assessment + sequence

    Two weeks: dependency mapping, traffic profiles, compliance constraints. Output is a migration sequence with explicit reversibility points.

  2. Strangler pattern

    We don't lift-and-shift; we strangle. New code lives in cloud, legacy code is fronted by an adapter, and traffic shifts gradually.

  3. Cost modeling

    Every migrated workload gets a predicted cloud cost before cutover. We tune for the bill, not just the deployment.
