Looking for DevOps services
or a cloud platform?
or a cloud platform?
We deliver open-source solutions end-to-end.
Start with FishOS Compute & Storage
FishOS is a production-ready cloud platform delivering the full infrastructure lifecycle — from deployment to upgrades and day-2 operations.
FishOS Ceph is software-defined storage based on fully open-source Ceph. It can be deployed as a standalone storage solution or as part of the FishOS cloud stack.
Licensing is CPU-core based, with enterprise support included.

Let us operate the cloud —
you focus on your business
With Hosted Cloud, Sardina Systems delivers and operates infrastructure on your behalf. You get the power of FishOS, OpenStack, or Kubernetes, and other solutions without managing the underlying platform:
- Minimal operational overhead
- SLA-backed infrastructure
- Full control without day-to-day management

Bring open-source cloud expertise on board
From architecture design to migrations, optimization, and long-term operations — our engineering team supports open-source cloud technologies from A to Z:
- Design and deploy private or hybrid clouds
- Migrate from VMware or legacy platforms
- Optimize performance, cost, and reliability
- Operate OpenStack, Kubernetes, and Ceph at scale

What Our Cloud Customers Say
“With DC4, Datacomm will not only meet the current demands but also position ourselves to offer more comprehensive and reliable services to our customers. The support from Sardina Systems within deployment was exceptional, enabling us to achieve a seamless integration. We are excited about the future and the possibilities that lie ahead with FishOS.”

“VMAccel has made use of Sardina’s expertise and knowledge in deploying compute and accelerator clouds for AMD and other AI players, empowering the future of AI and innovation. Who will you trust to bring your company into the new innovator economy?”
CEO of VMAccel AI Data Center, USA

“I was able to deliver a service to users within a week that would have likely taken us a month. The rapid provision of user functionality and the resulting ease in my workload are invaluable.
Considering its excellent support, functionality, and time-saving benefits, as well as the continuous availability of all systems, FishOS appears to offer excellent value for money.”

“OpenStack gives our research teams a self-service platform. They can launch virtual machines themselves, deploy tools, run analysis, share data — all without waiting for admin support. That level of autonomy is critical when you’re handling time-sensitive climate simulations or international collaboration projects.”

“Beyond meeting our technical requirements and offering the most attractive pricing
in the market, Sardina Systems stood out for their reliability and established technology. The personal approach during negotiations and the flexibility in addressing our concerns were also key factors in our decision-making process.”

“We needed a partner who could understand the complexities of managing private cloud solutions for diverse clients across Africa. FishOS supports an average of 250 VMs in the Sybyl system, enabling us to provide systems with a CPU capacity for up to around 1000 customers and facilitating the easy scalability of our business.”
Director of Cloud Service, Sybyl

“Right now, we have a couple of people actively managing our OpenStack cloud. That’s only possible because Sardina Systems provides us with the support and expertise we need. For a small team, that’s a huge advantage — it saves us time and resources while keeping things running smoothly.”
