Azure Architecture

I design Azure platforms that are secure by default and ready to scale, from the landing zone up: subscription structure, network segmentation, policy guardrails, identity, and the operating model that keeps it governable as it grows.

Problems I help solve

A cloud estate that grew faster than its governance
Inconsistent network, identity, and policy across subscriptions
No landing zone or platform foundation to build on
Cost and security drift with no guardrails
02

What I deliver

Landing Zones

Management group hierarchy, subscription design, and platform foundations aligned to the Cloud Adoption Framework.

What I deliver
A management group and subscription topology, platform and workload separation, and an identity and connectivity baseline, deployed as code.
Business outcome
New workloads inherit security and governance instead of reinventing them.
  • Azure Landing Zones
  • Bicep
  • Management Groups

Network Segmentation

Hub and spoke topology, Azure Firewall, private endpoints, and segmentation tiers.

What I deliver
A hub and spoke design, firewall and routing rules, private endpoints for PaaS, and documented segmentation tiers.
Business outcome
A breach in one workload stays contained.
  • Azure Firewall
  • Private Endpoints
  • VNet peering

Policy and Guardrails

Azure Policy as code and a least-privilege RBAC model.

What I deliver
Policy initiatives for security and cost, a least-privilege RBAC model, and deny and audit guardrails at the right scope.
Business outcome
Standards enforced automatically, and cloud spend reduced by 25% through right-sized, governed architecture.
  • Azure Policy
  • RBAC
  • Defender for Cloud

Operating Model

Naming, tagging, ownership, RACI, and runbooks.

What I deliver
Naming and tagging standards, ownership and RACI, and platform runbooks and handover.
Business outcome
The platform stays governable after I leave, run by your own team.
  • Azure CLI
  • PowerShell
  • Bicep

Cloud Migration and Modernization

Rehost, refactor, and modernize workloads onto Azure.

What I deliver
A migration assessment and wave plan, then rehost, refactor, or re-platform onto current Azure services.
Business outcome
Legacy estates moved to a secure, current platform.
  • Azure Migrate
  • App Service
  • Containers

Compute and Workload Architecture

Right-sized compute across VMs, AKS, and App Services with scaling and resilience.

What I deliver
Compute selection, autoscaling, and resilience patterns matched to each workload's profile.
Business outcome
Workloads that perform and scale without overspend.
  • AKS
  • Azure VMs
  • App Service

Resilience and Disaster Recovery

High availability, availability sets, and Azure Site Recovery.

What I deliver
An availability and DR design with replication, failover runbooks, and tested recovery objectives.
Business outcome
Business-critical systems that stay up.
  • Azure Site Recovery
  • Availability Zones

Cost Optimization and FinOps

Right-sizing, governance, and spend control.

What I deliver
A FinOps baseline with right-sizing, budgets, tagging, and policy-enforced cost guardrails.
Business outcome
Cloud spend reduced by 25% through governed architecture.
  • Azure Cost Management
  • Azure Policy

Work with me

Let me turn complexity into a system you can run.

Securing a Microsoft environment, planning a migration, or getting ready for Copilot. I help you make the call with clarity, then build it to last.
