The architecture grew organically
Services, accounts, subscriptions or network paths were added over time and the current design is difficult to explain or review as a whole.
Cloud Infrastructure Review
A focused AWS or Azure infrastructure review covering architecture, networking, IAM, Infrastructure as Code, reliability, backups, observability and cost visibility.
When to use it
The review is designed for existing AWS or Azure environments where the next infrastructure decision needs evidence rather than another generic best-practice checklist.
Services, accounts, subscriptions or network paths were added over time and the current design is difficult to explain or review as a whole.
Infrastructure changes have large blast radius, unclear dependencies or insufficient rollback and validation practices.
Roles, identities, service principals or permissions have accumulated and ownership or least-privilege boundaries are unclear.
State, modules, environment structure or reviewability make infrastructure changes harder than they should be.
Backups, failover paths, health checks or dependency behavior exist but are not clearly connected to recovery expectations.
Cloud costs are visible as totals, but it is unclear which architecture choices, unused resources or operating patterns are driving them.
Review scope
Exact depth depends on environment size and access, but the review follows the same operating model across AWS and Azure.
Service boundaries, account or subscription structure, shared dependencies, ingress and egress paths, and unnecessary coupling.
VPC or VNet design, routing, private access, DNS, load balancing, firewall boundaries and service-to-service connectivity.
IAM roles, managed identities, service principals, privileged paths, secret handling and machine-to-machine authentication.
Terraform or Terragrunt structure, state handling, module boundaries, drift risk and pull-request reviewability.
Availability assumptions, backups, recovery paths, health checks, scaling behavior and dependency failure modes.
Operational signal coverage, actionable alerting, ownership of cloud spend and architecture-level optimization opportunities.
Process
The review avoids turning every deviation from a reference architecture into a remediation project.
Identify business-critical workloads, accounts or subscriptions, regions, deployment paths and the decisions the review needs to support.
Use read-only access where practical, Infrastructure as Code, diagrams, configuration exports, monitoring and focused technical discussions.
Separate immediate operational risk from maintainability issues and lower-priority architecture debt.
Rank findings by impact, likelihood, effort and dependency rather than treating every issue as equally urgent.
Walk through findings, assumptions, implementation order and the decisions that should be made next.
Deliverables
The goal is not a long architecture report that becomes shelfware. Findings are structured around decisions, risk and implementation priority.
Evidence
An anonymized case study shows the same cross-layer approach applied to a real AWS to Azure migration involving private networking, API ingress, Functions, PostgreSQL and staged production cutover.
Migration from AWS Lambda, API Gateway and RDS to Azure Application Gateway WAF, internal API Management, Functions and private PostgreSQL.
Commercial boundaries
Scope is confirmed before access. Large estates or unusually broad reviews may require a higher fixed price or a staged assessment.
Review, findings, risk prioritization, recommendations and findings walkthrough within the agreed scope.
Large-scale Terraform refactoring, migrations, production remediation, penetration testing or continuous cloud cost management.
Selected findings can move into a separately scoped remediation or implementation engagement from €2,500.
