Your websites and software hosted, monitored and kept up to date, without you having to think about it. We keep your tools fast, secure and available, and step in as soon as something goes wrong.
What we do
- 01
Hosting
Infrastructure sized for your traffic, with HTTPS certificates, domain name and email set up correctly.
- 02
Monitoring
Continuous availability and performance checks, with alerts and intervention when an incident occurs.
- 03
Updates and backups
Regular security updates and backups so your data can be restored if something goes wrong.
- 04
Cloud and containers
Deploying your applications with Docker, scaling and automated releases.
Our solutions in detail
DevOps and CI/CD
Automated tests and deployments on every code change, so you release more often, cut manual errors and can always roll back.
LEARN MORECloud migration
Moving your websites, software and data to suitable cloud hosting, with a cutover rehearsed in advance and a rollback plan ready.
LEARN MOREManaged servers
Updates, security, tested backups and monitoring for your servers, entrusted to a single point of contact who documents everything.

Hosting and managed services from Bastia: someone who knows your code
When a website or application goes down, the first problem is often knowing who to call. The agency that built it points to the host, the host points to the code, and meanwhile your customers are waiting. At KALLISTACK, the same person designs, deploys and maintains: they know both the application and the server it runs on, which avoids the back-and-forth and speeds up diagnosis.
KALLISTACK is a company based in Bastia, founded by Alexandre Sciacca, a full-stack engineer with more than ten years of experience. We work with SMEs, startups and public bodies, in Corsica and beyond. Every enquiry gets a reply within 48 hours, and every quote states clearly what is included, what is not, and what is billed separately as a hosting subscription.
Which hosting, DevOps or cloud service fits your situation?
Needs vary a great deal from one organisation to the next. Here are some common situations and how we handle them.
- 01
You are launching a new website or application
We choose hosting with you that is sized for your real usage, prepare the launch and automate deployments from day one, so that every future change carries as little risk as possible.
- 02
Your current hosting is causing problems
Slowdowns, repeated outages, hard-to-reach support or an ageing server: we review the set-up, then either stabilise it or plan a migration to more suitable infrastructure.
- 03
Your releases are stressful
If every new version is deployed by hand and brings surprises, a DevOps approach, meaning a way of working that brings software development and operations together, makes releases repeatable, tested and reversible.
- 04
Nobody really looks after your servers
Overdue updates, backups never checked, access shared with former suppliers: managed services, where day-to-day server administration is handed to a provider, restore order and keep things on track over time.
Choosing the right hosting: data, GDPR and reversibility
We do not push a particular host. The infrastructure is chosen with you, according to your needs and your data constraints. The GDPR requires you to know where the personal data you process is stored and who can access it, so this criterion counts from the outset, alongside performance and budget.
We also attach great importance to reversibility: your ability to change provider without rebuilding everything. We make sure the domain name, hosting accounts and backups are in your name, we document the infrastructure and, where it makes sense, we package applications in Docker containers: standardised boxes holding the software and everything it needs to run identically on any server.
Finally, we size things carefully. A brochure website does not need the same architecture as a booking platform that has to absorb tourist-season peaks: oversizing costs money every month, undersizing costs customers.
How we run hosting and infrastructure projects
Whether it is a simple launch or a full infrastructure takeover, we follow the same steps.
- 01
Understand
We inventory what exists: websites, applications, servers, domain names, email, backups and access. We identify what is critical to your business and what can wait.
- 02
Design
We propose an architecture explained in plain terms, with the possible options, their strengths, their limits and their running costs, so you can decide with full knowledge.
- 03
Build and test
We install, configure and secure the infrastructure, automate what should be automated and check every point, including restoring backups, before anything goes live.
- 04
Launch and support
After go-live, monitoring, updates and improvements are handled under a maintenance or managed services contract matched to your needs.
What drives the cost of hosting and maintenance
We do not publish prices, because no two infrastructures are alike. The budget has two separate parts: the subscription paid to the hosting provider, billed according to the resources used, and our time for design, set-up and ongoing support.
The main factors are the number of websites and applications, traffic and data volume, the level of availability required, the number of environments (for instance a test environment alongside production), security and compliance requirements, the state of any existing set-up to take over, and the scope of support you want. The quote itemises each of these so you can make informed trade-offs. Where it helps, we set several options side by side, each with its set-up cost and its running cost, and the same point of contact stays with you throughout.
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.

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. Maintenance is tailored to the size of your website and your needs.
Shared hosting, virtual server or cloud: which should we choose?
Shared hosting puts many websites on one server and suits a simple, low-traffic site. A virtual server reserves resources for you and allows more freedom of configuration. Cloud infrastructure also lets you adjust resources to the load. We recommend the simplest option that genuinely meets your needs.
If you build our website, do we have to host it with you too?
No. We can deliver the website to the host of your choice, with the necessary documentation, or handle its hosting and maintenance ourselves. The decision is yours, and you can change your mind later.
Do you only work in Corsica?
No. We are based in Bastia and travel across the island, but hosting and managed services work perfectly well remotely. We also support organisations based elsewhere.
