Hosting and maintenance, in the cloud or on your own servers
We host your sites and software, keep an eye on them and keep them updated. You stop worrying about it. We keep your tools fast and online, and we're the ones who get the call when something goes wrong.
What we do
- 01
Hosting
Servers sized for your real traffic, with HTTPS, your domain and your email set up properly.
- 02
Monitoring
We watch uptime and speed around the clock, and step in when something breaks.
- 03
Updates and backups
Regular security updates and backups so your data can be restored if something goes wrong.
- 04
Cloud and containers
Your applications packaged with Docker, released automatically, and able to grow when traffic does.
Our solutions in detail
DevOps and CI/CD
Automated tests and deployments on every code change, so you release more often, avoid manual slip-ups and can roll back when needed.
LEARN MORECloud migration
Your websites, software or data moved to suitable cloud hosting, with a cutover rehearsed in advance and a rollback ready.
LEARN MOREManaged servers
Updates, security, tested backups, monitoring. Your servers in the hands of one contact who documents everything.

Hosting and managed services in Bastia, from someone who knows your code
When a website or an application goes down, the hardest part is often knowing who to call. The agency that built it blames the host. The host points back at the code, and in the meantime your customers are staring at a blank page. At KALLISTACK, whoever designs the application also puts it online and looks after it, knowing the code as well as the server it runs on. Diagnosis is faster. Nobody passes the buck.
KALLISTACK is a company based in Bastia. It was founded by Alexandre Sciacca, a full-stack engineer with more than ten years of experience. We work with SMEs, startups or public bodies, in Corsica as much as elsewhere. Every enquiry gets a reply within 48 hours. The quote draws a clear line between what is included, what isn't, and what you will pay the host directly as a subscription.
Hosting, DevOps or cloud, depending on your situation
Needs vary a lot. Here are the cases we see most often, and what we do in each.
- 01
You are launching a new website or application
We choose hosting with you, sized for real use. The launch is prepared and deployments are automated from day one, so later changes carry no pointless risk.
- 02
Your current hosting is causing problems
The site is slow, outages keep coming back, support doesn't answer, or the server has simply had its day. We start with an assessment. Then we either stabilise what you have or prepare a move to infrastructure that suits you better.
- 03
Your releases are stressful
If every new version is deployed by hand and comes with a surprise, a DevOps approach makes releases repeatable and tested, with a way back if something goes wrong. DevOps is a way of working that brings the people who write software closer to the people who run it.
- 04
Nobody really looks after your servers
Updates running late, backups nobody has ever checked, access still shared with former suppliers. Managed services means handing the day-to-day administration of your servers to a provider. It puts things back in order, then keeps them that way month after month.
Choosing the right hosting with GDPR and reversibility in mind
We don't impose any host on you. The infrastructure is chosen with you, based on your needs and the constraints on your data. The GDPR requires you to know where the personal data you process is stored, and who can access it. That criterion matters from the start, as much as performance or budget.
Reversibility matters to us too. It is your ability to change provider without rebuilding everything. The domain name, the hosting accounts and the backups are in your name, we document the infrastructure, and where it makes sense we package applications in Docker containers. A container is a standardised box holding the software with everything it needs, so it runs identically on any server.
Finally, we size things as tightly as we can. A brochure website doesn't need the architecture of a booking platform that has to cope with the peaks of the tourist season. Too big, and you pay every month for nothing. Too small, and the site gives way at the worst moment and you lose customers.
How we run hosting and infrastructure projects
Simple launch or full takeover, same steps.
- 01
Understand
We list everything that exists. Websites, applications, servers, domain names, email, backups, access. Then we separate what is critical to your business from what can wait.
- 02
Design
We propose an architecture explained in plain terms. Each option comes with what it offers, its limits, what it will cost every month, so you can decide with the full picture.
- 03
Build and test
We install the infrastructure, then configure it and lock it down before automating whatever should be automated. Nothing goes live until every point has been checked, restoring the backups included.
- 04
Launch and support
After go-live, a maintenance or managed services contract takes over the monitoring and updates, as well as any improvements. It is sized to what you need.
What drives the cost of hosting and maintenance
We don't publish prices, since two infrastructures are rarely alike. The budget comes in two clearly separate parts. On one side the host's subscription, billed according to the resources used, on the other our time, first to design and set things up, then to follow up.
Several factors weigh in. The number of websites and applications, the traffic, the volume of data. The level of availability you expect, and the number of environments (a test environment alongside production, for example). Security or compliance requirements count as well, along with the state of whatever we take over and how much follow-up you want. Each item appears in the quote, so you can make your own trade-offs.
Who this service is for
Any organisation that wants a website or software that just works, without handling the technical side. Whether or not we built your website, we can take over its hosting and maintenance.
How we work

Understand
We talk through your goals and budget. You get a quote you can actually read.
- T-2
Design
We map out the solution and the mock-ups, which you approve before any development starts.
- T-1
Build
We develop and test. You follow progress at every step.
- T-0
Launch & support
Go-live. After that we host it, fix it and keep improving it.

Frequently asked questions
Can you take over a website you did not build?
Yes. We first review the website and its hosting, then migrate or stabilise it before taking over maintenance.
What happens if my website goes down?
Monitoring alerts us, we diagnose the issue and restore the service. You are told what happened and what was done.
Is maintenance really necessary?
A website that is no longer updated becomes slow and vulnerable. How much maintenance you need depends on the size of the site, so we size it accordingly.
Shared hosting, a virtual server or the cloud, which should we choose?
The simplest option that genuinely meets your needs. Shared hosting splits one server between many websites; it is enough for a simple site with modest traffic. A virtual server reserves resources for you and gives more freedom in configuration. The cloud adds the ability to scale resources with the load.
If you build our website, do we have to let you host it too?
No. We can deliver the site to the host of your choice, documentation included, or host it and maintain it ourselves. It's your call. And you can change your mind later.
Do you only work in Corsica?
No. We are in Bastia and travel all over the island. Hosting and managed services, though, work perfectly well remotely. We also work with organisations based elsewhere.
