|b| Cloud & infrastructure

Operate the cloud, don't endure it.

Controlled migration to AWS, Azure, GCP or sovereign OVHcloud, Kubernetes orchestration and measured TCO reduction. Reproducible infrastructure, unified observability, quantified FinOps.

|b| Practices

Our practices

Six practices covering migration, operation and optimisation — with the numbers expected at the output.

01

Controlled cloud migration

From existing-system diagnosis to workload re-platforming — a prepared, sequenced, no-surprise switchover.

  • Current-state audit and dependency mapping
  • 6R strategy (rehost, replatform, refactor…)
  • AWS, Azure, GCP or sovereign OVHcloud migration
  • Hybrid coexistence, phased cut-over
  • Rollback plan, load tests before cut-over
02

Architecture & Well-Architected

Design of resilient, secure and cost-effective architectures — compliant with the chosen provider's Well-Architected framework.

  • Multi-AZ, multi-region when justified
  • End-to-end encryption, key management (KMS, HSM)
  • Event-driven, serverless, micro-services patterns
  • 5-pillar Well-Architected reviews
  • Disaster recovery plans (documented RTO/RPO)
03

Kubernetes & orchestration

Managed or self-hosted Kubernetes platforms — with the guardrails that production operations demand.

  • EKS, AKS, GKE or on-prem clusters
  • GitOps with ArgoCD or Flux
  • Service mesh (Istio, Linkerd) when needed
  • Auto-scaling, priorities and quotas
  • Policies (OPA, Kyverno), image scanning
04

Infrastructure as Code

Reproducible, versioned, reviewed infrastructure — one source of truth, zero untraced manual change.

  • Terraform, OpenTofu or Pulumi
  • Reusable modules and internal catalogue
  • IaC CI/CD: controlled plan, policy, apply
  • Drift detection and auto-remediation
  • Auto-generated documentation from code
05

Observability & SRE

Unified traces, metrics and logs — so we know what's happening before a user tells us.

  • OpenTelemetry, Grafana, Loki, Tempo
  • Contracted SLI/SLO, error budgets held
  • Noise-reduced alerting on actionable signals
  • Runbooks, blameless post-mortems
  • Structured on-call, documented handoff
06

FinOps & TCO optimisation

Understand, attribute and reduce the cloud bill — by action, not prayer. -30% TCO on average over 12 months.

  • Bill audit, team/product attribution
  • Reserved Instances, Savings Plans, strategic Spot
  • Automated rightsizing, orphan destruction
  • Cost-aware architecture (egress, storage tiering)
  • Monthly FinOps dashboard

|b| Use cases

Production use cases

01
Manufacturing
180 legacy VMs migrated to AWS EKS in 8 months, zero business interruption, -34% on monthly bill at iso-load.
02
Insurance
Sovereign Kubernetes platform on OVHcloud, SecNumCloud compliance in progress, 20-min RTO validated by DR exercise.
03
Retail
Serverless architecture for Black Friday, scaling from 12 to 1,400 RPS in 4 minutes, linear cost on traffic.
04
Healthcare
HDS + strict GDPR environment, end-to-end patient-record encryption, CNIL audit passed without remediation.
