Azure / Google Cloud architecture audit and review

Governance, identity and security, network, FinOps guardrails, resilience.

Format: 1 to 15 days, depending on the question

The problem

Subscriptions or projects have multiplied without a common framework, a go-live is approaching, or a security or compliance audit is coming up. You want an outside, written opinion before you decide.

What I do

  • I examine your Azure or Google Cloud landing zone: governance, identity and access, network, security, FinOps guardrails.
  • I interview the CIO office, security and platform teams, and I analyse the existing configuration: hierarchy, Azure Policy or Organization Policies, roles and privileges, costs.
  • For a critical application, I test its resilience: points of failure, recovery objectives (RTO, RPO), then a chaos engineering session with your teams, within an agreed scope.
  • I present my findings to management and to the teams.

Possible formats and deliverables

  • Decision workshop1 day

    For an architecture decision stuck between several teams or several options.

    • A documented, shared decision (ADR).
  • Architecture review4 to 8 days

    Before a go-live or a structural choice, to challenge an integrator’s architecture document, or to prepare or evaluate a tender.

    • A written, reasoned opinion.
    • The risks identified.
    • Recommended decisions, as ADRs.
    • A presentation session.
  • Resilience audit8 to 12 days · One critical application

    • A map of the points of failure, ranked by impact.
    • A documented business continuity plan and disaster recovery plan, with RTO and RPO objectives per component.
    • A report on the chaos engineering session.
    • A prioritised action plan.
  • Cloud foundation assessment15 working days · Azure or Google Cloud

    • A maturity score on 6 axes: identity and access, network, governance, security, costs, operations.
    • The 10 priority risks, ranked by impact.
    • A 90-day roadmap.
    • A presentation to senior management.

Track record

  • Azure Policy guardrails, FinOps included: allowed VM families and disk types.
  • Access governance: Entra ID PIM, least-privilege AKS RBAC; on Google Cloud, tag bindings, IAM conditions and Organization Policies.
  • Networking: hub and spoke, Private Endpoint, private DNS, Application Gateway and Azure Firewall on Azure; Shared VPC on Google Cloud.
  • I organised several simulated outage exercises, including the loss of a cloud zone, and fault injection on AKS clusters with Azure Chaos Studio.
