/platform/landing-zones
Landing zones
Management group hierarchy, subscription topology and policy baselines that still hold once you're past the first ten workloads.
Microsoft Azure · Cloud architecture consulting
Emerald Quant designs, builds and hands over Microsoft Azure estates — landing zones, networking, identity, infrastructure as code and cost control — for teams who have to run them long after we've gone.
Reference topology — every client estate starts as one of these drawings.
What we build
We don't sell transformation programmes. We take one part of your Azure estate, make it defensible, and leave the source behind so your engineers can change it without us.
/platform/landing-zones
Management group hierarchy, subscription topology and policy baselines that still hold once you're past the first ten workloads.
/network/hub-spoke
Hub-and-spoke VNets, ExpressRoute, Azure Firewall and private endpoints. Traffic paths your team can draw on a whiteboard from memory.
/identity/entra-id
Entra ID tenancy, conditional access, PIM and workload identities. Least privilege that people can actually work inside.
/iac/bicep-terraform
Bicep and Terraform modules, environment promotion and deployment pipelines. Every resource in the estate traces back to a file.
/migrate/assess-and-move
Assessment, wave planning and cutover for VMware estates, on-prem SQL and legacy .NET applications — including the ones nobody documented.
/cost/finops
Tagging standards, budgets, reservations and rightsizing. We publish the spend before and after, on the same chart.
The quant part
Every engagement opens with a read-only assessment against the five pillars of the Microsoft Azure Well-Architected Framework. You get a number per pillar, the evidence behind it, and the number we commit to reaching at handover.
Figures shown are the median across engagements completed in the last 24 months.
How we work
You can stop after any phase and keep everything produced in it — the assessment, the design records, the code. Nothing is held back to secure the next stage.
Weeks 1–2 · Assess
Read-only access, nothing changed. We map what exists, score it against the five pillars, and price the gap.
Weeks 3–5 · Design
Target architecture and decision records, reviewed line by line with your engineers before a single resource is deployed.
Weeks 6–17 · Build
We build alongside your team in your repositories. Pull requests, not slide decks. You review and merge everything.
Final 2 weeks · Hand over
Runbooks, dashboards and a working session with every on-call rota. Thirty days of support, then the platform is yours.

Start here
A two-week assessment tells you what you're running, what it costs, and what it would take to make it defensible. Fixed fee, read-only access, no commitment to anything after it.
