Managed IT — Servers & virtualisation

Servers and virtualisation tailored to your business

Your servers host your business applications, your files and your backups: when they fail, the business stops. We design, migrate and maintain Windows and Linux environments, virtualised on Hyper-V, VMware or Proxmox, with right-sized storage and a level of availability proportionate to the criticality of your business — in Paris and Île-de-France.

What holds you back

The patterns we keep seeing.

01

Servers reaching end of life

A server operating system that has reached end of support no longer receives patches: every newly discovered vulnerability stays open, and business software vendors stop validating their applications on it. Renewal is something you prepare — not something you improvise after a failure.

02

An outage that stops the business

When everything runs on a single machine, a disk or power-supply failure brings production to a halt. And without restore testing, your backup remains an assumption until the day you actually need it.

03

Capacity sizing done blind

Saturated storage, insufficient memory, virtual machines stacked up with no capacity plan: slowdowns set in and investment decisions get made without data. An inventory and ongoing capacity tracking restore an objective basis for those decisions.

What we cover

The scope of the service.

01 / SERVERS

Windows and Linux servers

Installation, hardening, updates and monitoring of your physical and virtual servers, on-premises or hosted.

  • File and print services
  • Domain controllers and directory services
  • Business application servers
  • Patches applied in agreed maintenance windows
  • Monitoring and alerting
02 / VIRTUALISATION

Hyper-V, VMware or Proxmox

Design and operation of virtualisation platforms suited to your context: machine consolidation, controlled migrations and upgrades.

  • A reasoned hypervisor choice based on your applications and licences
  • Migration of physical servers to virtual machines
  • Migration between hypervisors
  • Snapshots and machine templates
  • CPU, memory and storage capacity planning
03 / STORAGE & BACKUP

Storage and backup

Storage sized for your actual volumes, and backups whose restoration is tested — not just scheduled.

  • Volumes, shares and access rights
  • Disk redundancy
  • Local backup and an off-site copy
  • Documented restore tests
04 / AVAILABILITY

High availability and disaster recovery

Replication, failover and a recovery plan proportionate to the criticality of your applications, formalised in your service contract.

  • Replication between hosts or between sites
  • Failover if a host fails
  • A documented disaster recovery plan (DRP)
  • Periodic failover exercises
How we proceed

From scoping to follow-up.

The exact scope, deliverables and timelines are formalised in the proposal, before any commitment.

1
Audit of the existing estate

An inventory of servers, applications, dependencies, storage volumes and backups. It is the basis for sizing and costing.

2
Target architecture

Hypervisor choice, sizing, storage and availability level, presented with their costs and trade-offs so you can decide.

3
Planned migration

Cutover in batches, in windows agreed with your teams, with a rollback plan defined for every step.

4
Acceptance testing and documentation

Application testing, a restore test and delivery of the infrastructure documentation — which belongs to you.

5
Ongoing operations

Updates, monitoring, capacity tracking and regular reviews with your lead engineer to anticipate what comes next.

Frequently asked questions — managed it

The answers describe how the service works. Quantified commitments are formalised in your contract.

It depends on your applications, their latency requirements, your regulatory constraints and your licensing costs. Many SMEs keep a virtualised on-premises base for business applications and move email and collaboration to Microsoft 365. The initial audit exists precisely to decide this, application by application.
Yes, whether it runs on Hyper-V, VMware or Proxmox. The takeover starts with an inventory of hosts, virtual machines, storage and backups, followed by a documented stabilisation period. The precise terms of the transition are formalised during scoping.
Yes. The migration relies on an inventory of the machines, compatibility testing, a cutover in batches and a rollback plan. The schedule and maintenance windows are defined with you during project scoping.
It depends on the level of availability you have chosen: disk redundancy, replication of virtual machines to a second host, or restoration from backup. The recovery commitments attached to each scenario are formalised in the specific terms of your service contract.
Through regular, documented restore tests — not just by checking the logs. The data-loss and recovery-time objectives (RPO, RTO), along with the frequency of those tests, are defined in your service contract.
The cost depends on the number of servers and virtual machines, the storage volumes, the expected level of availability and the licences. A reliable estimate is only possible after the audit of the existing estate: it is the first deliverable of the scoping phase.
The infrastructure, the documentation and the credentials belong to you. Hand-back and reversibility — delivery of up-to-date documentation, transfer of administrator accounts and support for the incoming provider — are provided for in your service contract.
Yes, through VPN or secured remote access, depending on the chosen architecture. Access arrangements and the users covered are defined with you at the design stage, then formalised in the contract.

An audit, then a clear plan.
