Virtualisation with Proxmox Virtual Environment
Benefit from powerful, highly flexible virtualisation and cloud-hosting based on Proxmox VE: In the firstcolo data centres!
With features such as firewall macros, security groups and IP sets, Proxmox VE Firewall provides optimal protection for your virtual infrastructure. As a distributed solution, the firewall service runs on each node in your cluster. This results in complete isolation between virtual machines, while the firewall provides higher bandwidth than a centralised solution. With full IPv4 and IPv6 support, data traffic is always filtered for both protocols and your firewall regulations do not need to be maintained separately.
Virtual machines within a cluster can share a network bridge at all times. Essentially, each guest would terminate at the same switch and be able to communicate with one another. For added flexibility, Proxmox VE provides both VLANs and network aggregation. This, in turn, enables the creation of complex virtual networks within the cluster.
Role-based administration and multiple authentication sources also ensure a high level of security when accessing your cluster. In addition to a pre-integrated authentication server, Proxmox VE also supports Linux PAM, LDAP and Microsoft Active Directory. To avoid unauthorized access altogether, you can make use of two-factor authentication.
Virtual machines in shared storage (FC, ISCSI, NFS) can be migrated with no downtime. Since all nodes in the cluster constantly have direct access to the virtual machine disk image, the data does not have to be duplicated beforehand, which speeds up migration immensely.
For object storage in Proxmox VE, we exclusively use the natively supported Ceph storage. With the Ceph RBD and CephFS interfaces, storage is integrated directly on your cluster nodes. All administration takes place via an intuitive GUI. Data is always stored in triple replication and our in-house Ceph cluster enables transfer rates of up to 2 gigabytes per second.
The Storage Replication Stack (ZFS) is probably the most advanced storage type when it comes to data replicas and snapshots. Both VM images and container data consistently run on ZFS in the backend. The Storage Replication Stack increases the availability of business-critical data without using shared storage and at the same time minimizes data loss through asynchronous replication, as well as "live snapshot backup" function.

Virtualisation with Proxmox VE through firstcolo
Proxmox VE is a virtualisation platform for servers based on open source software (Debian/Linux operating system). It manages virtual networks and machines, high-availability clusters as well as containers and storage. This highly efficient virtualisation solution combines both KVM and container-based virtualisation.
Proxmox VE targets anyone looking for a highly available, secure platform for their virtualisation solution that is easy to use and saves costs through its efficiency.
