Leverage synergies and build your IT infrastructure from our services
The Proxmox virtualisation platform is designed for anyone seeking an adequate alternative to VMware in times of rising licence fees, or considering a virtualised IT solution as a service, whether on their own premises or in our data centre.
However, Proxmox is only one of the pieces of the puzzle within the ecosystem of Ceske Radiokomunikace’s IT services. We offer both IT infrastructure services (IaaS) – private, public, or hybrid – including their management (Managed Services), as well as operating platform services (PaaS). CRA’s data centres provide a secure environment for dedicated private cloud infrastructure solutions. These services are complemented by close cooperation with clients, collaboration and assistance in solving often non-standard requirements, during installations, updates, or in the deployment of new services.
Easy management, transparent costs, and high security go hand in hand with more than ten years of experience of our IT specialists. We do not sell packages, we design solutions tailored to our clients’ specific requirements and take care of their smooth operation.
What our clients say

IT manager of LUKROM systems
When looking for a new solution, we aimed to choose the best possible comprehensive infrastructure solution to which we could transfer all of the services provided at that time on our own server infrastructure, which was reaching its limits in terms of its lifetime. Having considered every aspect of our needs, we decided to move our servers over to cloud services. We were looking for a partner for long-term cooperation to support our business.

head of the infrastructure department, TOTAL SERVICE s.r.o.
What we appreciate most about CRA is its ability to respond to changes and requests flexibly and quickly, as well as the proactive and personal approach of specific experts and admins. Cooperation with CRA has always been fair and straight.
Vladimír Vojtíšek
CIO, WOOD & Company Financial Services
We have been running the IT infrastructure for our services on CRA’s public cloud for over four years,’ says Vladimír Vojtíšek, CIO of WOOD & Company. ‘CRA prepared a technically advanced solution tailored to our needs, which relieved us from the worries of infrastructure maintenance and administration, as well as scaling. As our company grew and expanded to other regions, the shared public cloud environment started to push its limits, especially in terms of the ability to optimally combine the operation of a large number of diverse applications.
ICT Director, HP TRONIC Zlín, spol. s.r.o.
Our company operates in a very dynamic and competitive environment where success is often determined by small details. Today, we consider maximum availability, stability, and reliability of information infrastructure to be a matter of course. To gain a competitive advantage, however, we need something extra, and that is what we are getting from CRA: accurately executed services which they deliver, above and beyond any contracts and SLAs, exactly when we need them.

What Proxmox Virtual Environment can do
Proxmox VE is an open-source virtualisation platform based on Debian Linux, with a web-based graphical user interface. In a single package, it combines virtual machines as well as containers, a high-availability cluster, a firewall, cooperation with various types of storage, live migration (moving running virtual machines and containers between servers without service interruption), the option to use software-defined networking (SDN), and the creation of a hyperconverged infrastructure (HCI).
No paid licences, low operating costs and independence from a single vendor, fast deployment with the possibility to gradually expand from a single virtual machine to a whole enterprise cluster. And a strong community on top.
A KVM + QEMU hypervisor is used for running virtual machines. KVM (Kernel-Based Virtual Machine) is a hypervisor built into a Linux kernel that uses CPU hardware virtualisation. Together with QEMU (Quick Emulator) at the user layer, KVM creates a running virtual machine.
LXC (Linux Containers) is used for operating system-level containerisation.
Proxmox allows working with various file systems and using common types of data storage, in particular:
- ZFS (Zettabyte File System) – a file system and disk volume manager in one. Its strengths include snapshot generation, replication, security, compression, and self-healing capabilities.
- Ceph – distributed SDS storage.
- NFS (Network File System) – a distributed file system protocol enabling file sharing between different systems.
- iSCSI (Internet SCSI) – a protocol for storage sharing over long distances via a network, using TCP/IP to transmit SCSI commands.
The Proxmox Backup Server, integrated into the Proxmox graphical user interface (GUI), provides a wide range of backup features, such as:
- Incremental backups and backup mode selection.
- End-to-end client-side encryption.
- Live Restore (rapid recovery) – the ability to start a virtual machine during restoration, significantly reducing downtime.
- Retention and maintenance.
A technological solution connecting virtualisation, storage, networks, and other IT resources into a single integrated system. It enables companies and organisations to simplify their overall IT infrastructure and increase efficiency and computing power, thereby reducing their total information system costs.
A network architecture that makes it possible to control the behaviour of a network as a whole using software, instead of having to configure each network element separately.
