Audit VMware avant migration: ce qui casse les plans trop propres
Retour de mission multi-sites: ce n'est pas l'inventaire qui bloque, c'est l'écart entre architecture déclarée, exploitation réelle et capacité de rollback.

Critical infrastructure. Direct senior expertise.
VSHIFT is a specialized infrastructure consulting firm. Not a generalist IT services company, not an isolated freelancer. Sharp expertise, applied directly to your critical projects.
01
Real enterprise VMware field experience
Production vSphere, NSX and vSAN environments — not certification labs. Every migration is approached with the rigor of a senior infrastructure architect who knows the edge cases.
vSphere 8NSX-TvSANvCenter
02
Production-first, never theoretical
Every architecture decision is evaluated by what holds at 3am on a Sunday. Tested rollback, documented runbook, defined escalation path before the first migration.
RunbooksRollback plansChange management
03
Direct senior technical involvement
You speak to the architect doing the work. Not a project manager delegating to an offshore team. Expertise is on the project, not in a presentation slide.
Single point of contactNo intermediary
04
Simplicity as an architecture principle
A well-designed infrastructure doesn't need to be complex. We eliminate superfluous layers, reduce the operational attack surface and document what needs documenting.

POC Support
Supervised Proxmox POC and structured
A POC without methodology is just a lab — it validates nothing credible. Our approach structures each step to give you a solid technical decision before any major investment.
Documented results at each phase
Architecture validated on real workloads
Objectively defined Go/No-Go
Operational runbook delivery
Team training included
01
Analysis & inventory
VM mapping, network analysis, storage and application dependencies.
02
Target architecture
Proxmox cluster definition, network strategy (VLAN, SDN), storage plan (Ceph/ZFS).
03
Network & storage
Proxmox SDN configuration, bonding, VLAN, IOPS and latency validation on target storage.
04
High availability
HA cluster configuration, migration policies, fencing and automatic failover tests.
05
DRP tests
Simulated failure scenarios: node failure, storage failure, split-brain. RPO/RTO target validation.
06
Production rollout
Wave migration, parallel run, application tests, controlled switchover and VMware decommissioning.
07
Operations & monitoring
Prometheus/Grafana setup, alerting, operational runbooks and team training.
Methodology

VMware après Broadcom : quelles conséquences pour votre infrastructure ?
Un an après la finalisation du rachat, les DSI mesurent l'impact réel. Ce n'est pas seulement une question de tarifs — c'est une remise en question de la trajectoire d'architecture sur cinq ans.

Construire un cluster Proxmox HA : architecture et pièges
Activer la haute disponibilité sur Proxmox n'est pas une case à cocher. C'est une architecture à concevoir, avec des composants critiques souvent mal compris : Corosync, quorum, fencing, stockage partagé.

Réduire le lock-in infrastructure : une approche pragmatique
La dépendance à un éditeur n'est pas un péché à effacer en urgence. C'est une variable d'architecture à comprendre, à mesurer, et à réduire progressivement selon les priorités réelles.

Ce qu'un POC Proxmox doit réellement valider
Un POC qui se contente de faire démarrer des VMs n'est pas un POC de validation — c'est une démonstration. Pour être un vrai instrument de décision, le POC doit tester ce qui échoue en production.

Migration: sans stratégie de rollback, la vitesse devient un risque
Retour terrain: en environnement critique, la maturité d'un programme se mesure d'abord à sa capacité de retour arrière, pas au nombre de lots passés.
