Architecture Audit

Take back control of your technical debt and costs

You no longer know where your technical debt stands? Cloud costs are rising without explanation? Incidents are multiplying? Our architecture audit gives you a clear, objective, and actionable view of your platform's state.

The challenge

Why businesses need an architecture audit

After several years of development, e-commerce platforms accumulate invisible complexity. Warning signs are often ignored until a major incident occurs:

No visibility on actual technical debt and its hidden cost
Cloud costs constantly rising without correlation to traffic
Recurring incidents whose root causes are never addressed
Degraded performance: slow pages, API timeouts, Core Web Vitals in the red
Unidentified security vulnerabilities, obsolete dependencies
Teams losing confidence in the platform and slowing down
Zero observability: problems discovered through customers
Architecture decisions made without objective data
Our methodology

End-to-end support, phase by phase

Each phase produces concrete deliverables. You maintain visibility and control at every step.

01 1 week

Scoping & Perimeter

Define the audit scope, understand business and technical challenges, identify stakeholders, and collect existing documentation. No generic audit — we start from your priorities.
Deliverables
  • Kick-off and alignment on audit objectives
  • Stakeholder interviews (CTO, leads, ops, business)
  • Existing documentation collection (architecture, ADR, runbooks)
  • Initial mapping of systems and critical flows
  • Priority risk zone identification
  • Evaluation criteria and scoring definition
  • Detailed audit schedule and required access
  • Audit RACI matrix
02 2 to 3 weeks

Architecture & Code Audit

Deep-dive analysis of application architecture, code quality, dependencies, and technical debt. We objectively measure what's slowing your velocity.
Deliverables
  • Application architecture review (patterns, coupling, cohesion)
  • Static code analysis (complexity, duplication, test coverage)
  • Dependency and version mapping (CVE, obsolescence)
  • Technical debt assessment (quantified in person-days)
  • CI/CD practices and quality gates review
  • Database analysis (schema, queries, indexes)
  • Maintainability and scalability assessment
  • Per-component scoring with criticality level
03 1 to 2 weeks

Performance & Security Audit

Test performance under load and your platform's security posture. Identify vulnerabilities before they become incidents.
Deliverables
  • Load and stress testing (k6, JMeter, Artillery)
  • Core Web Vitals analysis (LCP, FID/INP, CLS) page by page
  • Automated vulnerability scanning (OWASP Top 10)
  • Authentication and authorization practices review
  • Attack surface analysis (APIs, exposed endpoints)
  • PCI DSS / GDPR compliance verification where applicable
  • Resilience testing (failover, recovery, graceful degradation)
  • Vulnerability report classified by criticality (CVSS)
04 1 to 2 weeks

Infrastructure & Cost Audit

X-ray your cloud infrastructure, identify overprovisioning, observability gaps, and possible cost optimizations.

Deliverables
  • Detailed cloud cost analysis (per service, per environment)
  • Overprovisioned resource identification (right-sizing)
  • Observability assessment (logs, metrics, traces, alerting)
  • Network architecture and perimeter security review
  • Scaling strategy analysis (auto-scaling, capacity planning)
  • Disaster recovery and backup assessment
  • IaC and environment reproducibility review
  • TCO projection over 12 to 36 months with optimization scenarios
05 1 week

Presentation & Roadmap

Present results in an actionable manner, with a prioritized action plan and remediation roadmap. Each recommendation is quantified in effort and impact.

S1S2S3S4S5
Deliverables
  • Complete audit report with per-domain scoring
  • Executive presentation for the board / C-suite
  • Prioritized action plan (quick wins, medium-term, structural)
  • 90-day remediation roadmap
  • Budget estimation for recommended remediations
  • Optimized TCO projection vs current state
  • Tooling and process recommendations
  • Knowledge transfer session with teams
Business value

What you concretely gain

Expected results

Critical risk identification

Infrastructure cost reduction

Performance improvement

Critical risk identification

Security vulnerabilities, single points of failure, obsolete dependencies — every risk is identified, classified, and documented before it becomes an incident.

Infrastructure cost reduction

Cloud resource right-sizing, unused service removal, scaling optimization — our audits reveal an average of 20 to 40% savings on infrastructure costs.

Performance improvement

Green Core Web Vitals, optimized API response times, bottlenecks identified — every millisecond gained translates into conversion and user experience.

Strengthened security posture

OWASP Top 10 covered, PCI DSS and GDPR compliance verified, attack surface mapped — you know exactly where you stand and what remains to be done.

Actionable and prioritized roadmap

No report that ends up in a drawer. Each recommendation is quantified (effort, impact, cost), prioritized, and integrated into an immediately executable 90-day plan.

Team alignment

The audit creates a shared diagnosis between tech, product, and management. Everyone leaves with the same view of the current state, priorities, and action plan.

Frequently asked questions

Your questions, our answers

01 How long does a complete architecture audit take?
Between 6 and 9 weeks depending on scope (number of applications, infrastructure complexity, number of markets). The initial scoping phase allows precise duration calibration. A focused audit (performance only or security only) can be completed in 2 to 3 weeks.
02 What access is needed to perform the audit?
Read access to code repositories, access to staging environments (never production directly), access to monitoring dashboards and cloud consoles (read-only). We systematically sign an NDA and work within a security framework defined together.
03 Will the audit disrupt our production environments?
No. Code and architecture analyses are performed outside production. Load tests are run on staging or pre-production environments. If a production test is necessary (security scan for example), it is scheduled during off-peak hours with your prior approval.
04 What is the difference from an audit by a traditional consulting firm?
We are practitioners, not PowerPoint consultants. Our auditors are senior architects and developers who read the code, configure testing tools, and analyze metrics themselves. The deliverable is technical, actionable, and directly usable by your teams.
05 What happens after the audit presentation?
You leave with a prioritized action plan and a 90-day roadmap. We can support the implementation of recommendations if you wish, or transfer the plan to your internal teams. A 3-month follow-up is offered to measure progress.
06 Does the audit cover regulatory compliance (PCI DSS, GDPR)?
Yes, if it's within the scope defined during scoping. We verify technical compliance with PCI DSS requirements (for direct payments), GDPR (personal data, consent, retention periods), and OWASP security best practices. The audit does not replace an official certification but identifies the gaps to close.
