⏚ Summary

What this engagement is, plainly.

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.

Problems we solve

  • 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.

⏚ Approach

How we run this engagement.

  1. 01Phase

    Assessment + sequence

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

  2. 02Phase

    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. 03Phase

    Cost modeling

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

⏚ Deliverables

What you get, signed off.

  • Migration assessment + sequence document

  • Network + identity bridge

  • Strangler-fig adapter for legacy systems

  • Per-workload cost model

  • Cutover runbooks + rollback paths

⏚ Stack we typically use

Tools, not religion.

We pick on workload and team shape, not on fashion. Anything below is a default — swappable when your context demands.

  • AWS
  • GCP
  • Azure
  • Terraform
  • Crossplane
  • Direct Connect
  • DMS

Outcome

A cloud estate that's been migrated piece by piece, with the bill modeled, the operations team trained, and the legacy footprint shrinking week over week.

Have a hard problem worth doing once, well?

We take a small number of engagements per quarter. If your program needs serious operators, we'd like to hear about it.
