Enterprise Virtualisation with Proxmox VE
As an open source solution for enterprise virtualization, Proxmox combines KVM hypervisors and Linux containers (LXC) in addition to software defined storage and network functionalities on a single highly performant platform.
High availability cluster
By combining two virtualisation technologies, KVM and LXC, Proxmox VE provides you with great scalability, high availability and eliminates single points of failure (SPOF) through multi-master design.
The integrated HA manager additionally monitors all virtual machines and containers on the entire cluster and reports immediately if one of the nodes fails.
The central user interface additionally simplifies the operation of virtual machines and containers with functionalities such as web-based CLI, a “REST-like” API, as well as live migration without down time.
Your advantages when moving into the First Colo Proxmox VE Cluster
Consolidation of servers and computing resources
Maximum availability and performance
Simple and versatile scaling options
Lower infrastructure costs
Flexibility through convenient APIs and GUIs
Effortless configuration with confidence security
With the assistance of previously integrated services such as backup and restore, firewall, and storage replication Proxmox VE greatly reduces the complexity of your network configuration.
By featuring firewall macros, security groups and IP sets, the Proxmox VE firewall provides optimal protection for your virtual infrastructure. As a distributed solution, the firewall service runs on every node in your cluster. This results in complete isolation between the virtual machines, while the firewall provides higher bandwidth than a centralised solution.
With full IPv4 and IPv6 support, traffic is always filtered for both protocols and firewall rules do not need to be maintained separately.
Within a cluster, virtual machines can always share a network bridge. Any guest would therefore terminate at the same switch and can thus communicate with one another without problems.
Proxmox VE also provides VLANs and network aggregation for additional flexibility. This allows for the establishment of complex virtual networks within a 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. You can make use of two-factor authentication to prevent unauthorized access entirely.
Uncompromising data growth through software-defined storage
Whether local storage, shared storage, or distributed storage, the software defined storage model of Proxmox VE is very flexible and support all storage technologies for Debian Linux on block level, object level, and file level.
Virtual machines in shared storage (FC, ISCSI, NFS) can be migrated without downtime during operation. Data does not have to be immediately replicated, since all nodes in the cluster always have direct access to the disk-image of the virtual machines. This accelerates the migration substantially.
In terms of object storage in Proxmox VE, we only use the native supported Ceph storage. With the interfaces Ceph RBD and CephFS the storage is integrated directly on your cluster nodes and the whole administration is done via an intuitive GUI. Data is always stored threefold and our in-house Ceph cluster allows transfer rates of up to 2 GB 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 always run on ZFS in the back end. The Storage Replication Stack increases the availability of business-critical data without the use of shared storage, while minimizing data loss through asynchronous replication and “live snapshot backup” functionality.
