What is an MSP and when your company needs one (and when it does not)

In almost every company there comes a point where the business grows faster than the infrastructure holding it up. The team fights fires instead of building, one single person is the one who "knows how it all works", and every update is done holding your breath. That is where the word MSP shows up. Let us explain what it actually is, without the brochure jargon, and when it makes sense for you and when it does not.

What an MSP is, without the jargon

MSP stands for Managed Service Provider. In plain terms: someone who designs, deploys and operates your IT infrastructure for you, continuously and with 24/7 service behind it, instead of selling you a box and vanishing. That is exactly the difference from a reseller. A reseller places product and takes a commission; an MSP takes responsibility for that thing still working tomorrow at three in the morning. We are not resellers of a particular platform: we recommend based on the case, not on the commission.

A real MSP is vendor-agnostic and works in layers: the infrastructure and cloud underneath, virtualization (including VMware to Proxmox migration when licensing spikes), the application platform with managed Kubernetes and CI/CD, the network, security and continuity. It is not "I handle your email": it is taking charge of the whole system so that growing does not mean more scares.

When your company already needs one

You do not need to be a giant. The signs are usually these, and one or two already means it is time to talk:

• Infrastructure is a single point of knowledge. If "how it all works" lives in one person's head, you already have a continuity problem, not a technology one.
• You fight fires instead of building. The team spends the day reacting and never gets to what actually moves the business.
• Your product grows faster than your platform. Software teams that cannot scale their infrastructure at the pace of their users: that is a classic MSP case.
• Compliance and continuity start to weigh. Backups nobody has tested, a DR that is a document and not a drill, a client already asking you for guarantees in writing.

And when do you not need one? If you have an in-house team that knows your stack, the infrastructure is documented and comfortably sized, and you are not in a moment of growth or change, an MSP is unnecessary. We would tell you as much: part of doing this job well is knowing when the right move is to touch nothing.

Judgement, not a catalogue

The difference between an MSP that adds value and one that just invoices is judgement. We run our own platform in production —virtualization with Proxmox, distributed storage with Ceph, containers with Docker Swarm and Kubernetes, monitoring with Zabbix, our own BGP network— so when we design yours we do not experiment: we apply what already holds ours up. And we do it with one fixed idea: failure is inevitable; an outage is a design decision. A good MSP does not promise nothing will ever break —that is a lie—; it makes sure that when something breaks, the business does not stop.
