What is the difference between a virtual server and dedicated server?
At this point, we would like to explain a few terms, just as these are used for our products.
A virtual server is often referred to as VPS (virtual private server), VM (virtual machine), v server, or virtual server. These are installed on a host server. On a host, several virtual servers can be operated with different operating systems. This means that more than one customer can be set up simultaneously on one host. The individual virtual servers are clearly separated from each other.
Dedicated servers are also known as root servers. The server is exclusively available for one customer. The customer receives the full performance and all resources of the host on its own, does not have to worry about the maintenance of the server or technical defects. The customer can therefore concentrate entirely on his project.
A root server in the classical sense is a root name server and as such is responsible for the name resolution on the Internet. The root servers know the names and IP addresses of all nameservers of all top-level domains (TLD). The root servers are coordinated by the ICANN (Internet Corporation for Assigned Names and Numbers).
We do not use the term root server for our products.
Differences between virtual and dedicated servers
- Virtual servers do not have their own physical disk. A file with the appropriate size will be assigned to you and the vServer is installed here.
- The memory is virtually assigned to the v-Server. For the memory swap there is set up a swap partition on the disk.
- You can flexibly allocate vCPU. Only a reboot is required.
- The network interfaces are virtually assigned to the v server.
- Time: The time of the host is automatically synchronized with a time server and cannot be changed within the Virtual Server. Deviations are thus automatically corrected.
