Virtualisation

Virtualisation – a big step in times of digitalisation

For quite a while now there is a possibility for customers of First Colo GmbH to make use of a virtual environment over traditional bare-metal-servers. For such an environment, the software-solutions we provide you with are comprised of either Proxmox or VMware. As an official partner of Proxmox, First Colo already takes care of multiple well-known customers, which make use of virtualisation.
Customers can decide whether they would like an environment, which is managed by First Colo directly (Managed-Hosting), or whether they would like to manage the environment, themselves (Self-Hosted). A managed-hosting environment offers a great advantage, which is that customers will be able to completely focus on their core business at all times. First Colo will execute the entire management of the cluster-infrastructure for its customers (Full-Management).

What are the solutions First Colo can offer?

VMware:

As for VMware, First Colo offers customers a completely separate resource-pool based on a shared-cluster system. When making use of the VMware Vcloud Director, there is a possibility for customers to administer a fixed amount of resources “independently”. Thereby, customers are able to manage their own virtual machines. The storage component is met by VMware’s vSan and all clusters are exclusively offered with 100% SSD-storage. Next to shared-cluster infrastructures, First Colo also offers so called managed dedicated VMware-clusters.

Proxmox:

First Colo offers both managed as well as unmanaged Proxmox-clusters. A typical cluster-setup generally contains at least three nodes, so that an adequate level of redundancy can be realised at all times. The storage component of such a cluster will be made available via First Colo’s Ceph-Storage. While doing this, both the individual hypervisors as well as the Ceph-Storage at large are being connected to First Colo’s network at a speed of 10 gbit/s. First Colo’s Ceph-Storage is comprised of 100% SSD-storage, and thus offers exceptionally high performance. Lastly, the billing of the storage volume is done in a pay-as-you-grow scheme to make it more customer friendly.
A big advantage of virtualisation at large is the increased availability, which stems from the abolishment of a need for a connection to a single physical server. Therefore, applications can be migrated easily and are protected from undesirable downtime. Additionally, another advantage is the reduction in costs, since a lower amount of physical servers leads to a decrease in the need for electricity and cooling. Thus, the establishment of virtual servers in most cases is cheaper and furthermore, also more sustainable for the environment at large.
Although, the biggest advantage of virtualisation is scalability. Customers have the possibility to demand additional resources at short notice, as long as they are still within the boundaries of the available capacities (physical limit of the hardware). It is important to note, that the amount of physical nodes in the cluster can be increased at all times. These reasons make virtualisation a great alternative to traditional hosting solutions.
