Multi-cloud architecture
Landing zones and reference architectures that hold up under audit and stay cheap.
What we ship
A landing zone that an enterprise security team will accept on first review. Network topology, identity model, policy-as-code, logging pipeline, budget guardrails, and a written rationale for every decision.
On Azure: management group hierarchy, hub-and-spoke with Azure Firewall or NVA, Entra ID with conditional access, Defender for Cloud baseline, Azure Policy assignments, custom diagnostic settings to a central Log Analytics workspace.
On AWS: Control Tower or hand-rolled multi-account, Transit Gateway hub, IAM Identity Center, Security Hub baseline, SCPs, CloudTrail Organization Trail. On GCP: organization hierarchy, Shared VPC, Cloud Identity, SCC, custom org policies.
Why the scope is predictable
Cloud landing zones are well-understood. The scope is finite. We have shipped enough of them that estimation is precise. You get the deployed infrastructure plus the architecture decisions document, not a stack of slides and a change-order request.
Cost outcome
Every engagement includes a cost-recovery pass: spot reservations, idle resource cleanup, right-sizing, savings plans, commitment discounts. Typical month-one cut on a single workload is twenty to thirty percent. We document where every dollar went so finance can sign off.
