IT Infrastructure
The floor everything else stands on
Networks, compute, storage and the operating model around them — designed to be changed safely rather than frozen once it works.
What changes when the floor is solid
Figures from estates we currently run, measured against the operating model each client started with.
- Average run-cost reduction
- Markets on one operating model
- Contracted platform availability
- Follow-the-sun operations
Overview
Infrastructure designed to be changed, not frozen
Most estates are not badly built. They are built once, correctly, for a set of assumptions that has since moved — and then defended rather than revisited, because nobody can say with confidence what a change would break.
We take the estate apart on paper first: what runs where, what depends on what, and which of those dependencies anyone has actually tested. The re-platforming that follows is the easy half. The half that decides whether it lasts is the operating model handed over with it.
- Named rollback owner for every migration step, agreed before anything moves
- Capacity and cost modelled per workload, not per environment
- Runbooks written by the team that will be on call for them
Capabilities
What we do
Two engagements, depending on whether the estate needs moving or needs running. Most clients start with the first and keep us for the second.
Move the estate without re-risking it
A migration is a sequence of reversible steps or it is a gamble. We plan it as the former: every wave has an exit, the old path stays warm until the new one has carried real traffic, and the cutover is a decision someone makes rather than a date that arrives.
Estate discovery
Dependency mapping from live traffic, not from the CMDB — the two rarely agree.
Landing zones
Accounts, networking and guardrails set up once, so the tenth workload costs less than the first.
Wave planning
Workloads grouped by blast radius rather than by business unit.
Cutover rehearsal
Full dress rehearsal against production data before the real window.
