Infrastructure & on-site

Should you keep an on-premises infrastructure or move everything to the cloud?

Moving everything to the cloud is not always the right choice, and neither is keeping everything on site. The real question is not the trend of the moment, but what your activity, your constraints and your premises genuinely justify.

Should you move everything to the cloud? The honest answer is: it depends. The cloud brings a lot, but a well-run on-premises infrastructure remains the right choice for many organisations. The real question is not to follow the trend, it is to look at what your activity, your constraints and your premises genuinely justify.

When on-premises still makes full sense

A local infrastructure is in no way a sign of being behind. Business applications that run locally, performance needs, a requirement to keep certain data within your walls, or simply an estate that works: all are legitimate reasons to keep part of your IT on site.

The question of where your data should live often weighs heavily in that choice. On-premises deserves to be served on its own terms, not treated as a transitional step before the cloud.

What a managed on-premises infrastructure covers

Managing on-premises is not just “having a server”. It is holding the whole together: the network and its access, the servers and virtual machines, local identities and access, printing, the physical firewall, local backup. Well managed, these elements are as reliable and as closely followed as a cloud environment.

The cloud, where it really adds value

Conversely, some things gain from leaving your walls: an isolated server that creates a risk if it fails, an application that can be hosted elsewhere, a continuity need the cloud serves better. Migrating what makes sense, keeping the rest, is often the best combination.

The right answer is rarely “all or nothing”

Most organisations live very well with a mix of the two. What matters is not the location in itself, it is that the whole is coherent and managed by a single point of contact, who knows what runs where and why. Migration then stays an open possibility, to act on when it brings a clear benefit, never a forced step.

That is the spirit of our On-premises offer: your local infrastructure taken in hand properly, with the move to the cloud available on the day it makes sense, and not before.

Frequently asked

Is on-premises outdated?
No. For some activities, a local infrastructure remains the right choice: performance constraints, specific business applications, data-location requirements, or simply an estate that works well. On-premises is not a sign of being behind, it is an answer to a need.
What exactly counts as on-premises?
Everything that lives within your walls: the network, local servers, internal identities and access, printing, the physical firewall, local backup. It can be managed just as cleanly as a cloud environment.
Can you mix on-premises and cloud?
Yes, and it is very common. Many organisations keep some things on site and hand the rest to the cloud. The essential thing is that the whole is managed coherently, by the same people.
Should you migrate if everything already works well?
Not on principle. A migration is justified by a real benefit, not by fashion. If your current setup does its job, evolving it stays an open option, never an obligation.
