Why this matters

An Azure tenant is not an architecture.

Most mid-market Azure environments grew one project at a time. There is no landing zone, no governance baseline, and no shared model for networking, identity or cost. Every new initiative pays for the absence — in hidden spend, in migration friction, and in security exposure.

We modernise the environment around a defensible target architecture: a landing zone, governance guardrails, and a migration path scoped to your workload reality — not a textbook reference design.

What it includes

Six work-streams, scoped to your environment.

01

Landing zone design

Azure landing zone aligned to Microsoft's Cloud Adoption Framework, scoped to your subscription topology and operating model.

02

Network & connectivity

Hub-and-spoke design, ExpressRoute or VPN sizing, segmentation, and DNS strategy.

03

Governance guardrails

Policy-as-code, tagging strategy, RBAC model, and management group hierarchy.

04

Migration assessment

Application portfolio assessed against the 6Rs — rehost, replatform, refactor, repurchase, retire, retain.

05

Workload migration

Wave-planned migration with cutover support, rollback design and dependency mapping.

06

FinOps instrumentation

Cost visibility, tagging, reservation strategy and chargeback instrumented — handed to internal finance and IT as an operating practice, not a one-time report.

Engagement sequence

How a modernisation runs.

STEP 01 · WEEKS 1–3

Architecture review

Current Azure estate documented and assessed against the target reference architecture.

→ Architecture gap report
STEP 02 · WEEKS 3–6

Target design

Landing zone, network and governance designed and signed off.

→ Approved target architecture
STEP 03 · WEEKS 6–14

Foundation build

Landing zone, guardrails and connectivity delivered. Pilot workload migrated.

→ Production-ready foundation
STEP 04 · WEEKS 14–20

Migration waves

Workloads migrated in scoped waves with cutover, validation and FinOps handover.

→ Modernised estate, governed

Outcomes

What you have at the end.

PREDICTABLE

Cloud spend you can forecast.

FinOps instrumented — tagging, reservations and chargeback in place. Variance against forecast typically inside 10%.

DEFENSIBLE

An estate that can carry transformation.

Landing zone, guardrails and connectivity engineered for AI, data and M365 workloads sitting on top.

OWNED

Governance your IT team operates.

Policy-as-code and operating model handed to internal IT — not retained as ongoing managed service.

Before you start here

Foundations check

Modernisation moves quickly only if the underlying readiness review has been completed. If you have not had an AI-Ready Architecture Review, start with a Readiness Conversation — we can scope both in sequence.

The next step

Modernise on a foundation engineered to carry it.

Forty-five minutes with a senior architect. We'll ask about your Azure topology, governance posture and migration ambitions — and tell you honestly where to start.
