Cloud migration for businesses in Corsica
Cloud migration means moving your websites, software or data to infrastructure rented from a specialist provider and reached over the internet. They leave a server on your premises, or an old host. We prepare the operation, carry it out and secure it for SMEs, startups or public bodies, in Bastia, across Haute-Corse and beyond. The aim is to get you to the cloud without losing a single piece of data, with downtime kept as short as possible.
Moving to the cloud, what gets moved and why
The cloud means servers and IT services rented remotely. You pay for what you consume and scale them without buying hardware. Migrating doesn't mean moving everything. You choose, item by item, what is better off hosted remotely.
- 01
Websites and web applications
A brochure site, an online shop, an extranet or a booking platform, often sitting with an old host or on a server that has had its day.
- 02
Business software
Applications installed on an in-house server that your teams would like to use from several sites or on the move.
- 03
Databases and files
The data your tools work with. It has to be transferred without losing anything, and without inconsistencies between the old system and the new one.
- 04
Related services
Domain names, HTTPS, emails sent by your applications, backups. They are details, but one oversight is enough to cause an outage on cutover day.
When does a cloud migration make sense?
- 01
A server at the end of its life
The hardware is ageing, the system no longer gets security updates, the failures come closer together. Replacing it with a rented server spares you another hardware purchase.
- 02
A host that no longer suits you
Slow pages, support you can never reach, an offer that never changes. Changing host is a migration in its own right, and should be prepared like one.
- 03
Fluctuating demand
The tourist season brings its traffic peaks, so does the odd campaign, and sometimes growth takes off. The cloud adjusts resources instead of making you pay all year for the busiest period.
- 04
Dispersed teams
Several sites, remote working, travel. A hosted tool can be reached from anywhere over a secure connection.
- 05
And when it does not make sense
If an application has to work without the internet, or your premises' connection can't keep up, a local or hybrid setup is better. We'll tell you plainly.
Business cloud hosting, how to choose
We don't impose any provider. Hosting is chosen with you, based on your needs and the constraints on your data, by comparing several options against criteria written down in black and white.
- 01
Data location and the GDPR
Where is the data stored, under which jurisdiction, and who can access it? In France, some data, health data for instance, can only be entrusted to a host recognised for that purpose.
- 02
Type of service
A virtual server you administer yourself, a managed platform where the provider handles the system, plain storage space for files. Each option moves the line between what you manage and what the provider manages.
- 03
Predictable costs
Pay-as-you-go is flexible, but the bill can drift. We estimate usage in advance and set up spending alerts.
- 04
Reversibility
It must remain possible to leave the provider without rebuilding everything. Docker containers and documented configuration make that exit far simpler.
The stages of a well-prepared cloud migration
- 01
Inventory
We list the applications and the data, the links between them, the access, the usage. That way we know exactly what has to move, and in what order.
- 02
Migration plan
A written plan sets the order of operations and the moment of cutover, the instant your users switch from the old infrastructure to the new one. It also lists the checks to carry out and the route back if needed.
- 03
Preparing the target
The new environment is built with its security and backups, then its monitoring, before anything is transferred to it.
- 04
Dry run
A dry-run migration, on a copy of the data, measures how long the transfers really take. Problems get fixed at that stage, with no consequences.
- 05
Cutover and checks
At the time that disrupts your business least, we transfer the up-to-date data and redirect traffic, then check every function. The old system stays intact until the new one has proved itself.
What you receive once the migration is complete
You get documented infrastructure. The file includes an architecture diagram, the list of services, the procedures for backup and restore, plus access details and useful contacts. The hosting accounts are opened in your name, or at the very least you hold the main access. A migration report records what was moved, the tests carried out and what is still to be dealt with. As for the old system, a full backup of it is kept for as long as agreed with you.
The risks of a migration, and what we do to limit them
- 01
Lost or inconsistent data
A full backup before any operation. Then verified transfers, and a comparison between the old system and the new one.
- 02
Service interruption
The cutover is scheduled for a quiet moment and rehearsed beforehand. A rollback remains possible.
- 03
Domain names and email
DNS is the internet's directory, linking your domain name to a server. It has to be changed carefully, so neither the website nor the email goes down.
- 04
Costs that creep up
Oversized resources, or ones forgotten in a corner. After go-live, we fine-tune and keep an eye on usage.
- 05
Misconfigured security
A storage space left open to the public by mistake, and your data leaks. All access is closed by default, then opened case by case.
What a migration costs, and support after cutover
The cost depends on how many applications there are and how old they are, on the volume of data, on the dependencies between systems. Availability constraints play a part too, since a cutover at night or over a weekend needs more preparation. Then come the regulatory requirements, and the state of the existing documentation. The host's subscription is added on top and depends on the resources chosen; we show it separately so you can compare the options.
After cutover, we monitor the infrastructure, then adjust resources and costs to real usage. Day-to-day administration can then move under the management of your servers, as can the automation of your deployments.

Frequently asked questions
Is the cloud cheaper than a server on our premises?
Not necessarily. You stop buying hardware and you pay for what you use, but the subscription comes back every month. The gain often lies elsewhere, with fewer hardware failures to deal with, access from anywhere, resources you can adjust. Before any decision, we compare both scenarios with you.
Where will our data be hosted?
Wherever you decide, after a comparison. The choice is made with you according to your needs and constraints, in particular the GDPR and how sensitive the data is. Afterwards you know exactly where it is stored.
Will our business be interrupted during the migration?
Sometimes briefly, at the moment of cutover. We place it at the time that bothers you least, rehearse it beforehand, and you know exactly how it will go.
Can we change host later?
Yes, and we prepare for it from the design stage. With documented infrastructure and containerised applications, plus accounts in your name, a future move becomes much simpler.
Do we need an excellent internet connection to move to the cloud?
It matters, especially if your teams spend the day on online tools. We check it during the inventory. If it is too weak, we take that into account, with a hybrid setup, a local copy of some files or a gradual migration.
