"I have a problem with my server. Please be forgiving if I ask you some not so smart questions." Many such sentences are read in various forums and blogs. Those interested in IT are thrown into the cold water, where they drown. So let's start from scratch …

vServers, dedicated servers, root servers; all kinds are found on the Internet, yet it is precisely the newcomer who finds the introduction to this subject very challenging. Generally speaking, servers are efficient physical computing systems used for hosting websites or software applications. They are characterized by the fact that several users from different locations can access them simultaneously. Similarly to PCs, servers also have fixed performance characteristics such as hard disk size, working memory (RAM) and processor performance (CPU).

Virtual servers (in short: vServers), also function according to this principle, but they use only a fixed part of the hardware resources and have therefore other performance characteristics than underlying physical servers. Thanks to special software, the resources of the physical server can be allocated flexibly and in a tailor-made way. Keyweb offers four different vServers, just choose the model most suitable for you. Do you already have one? If your needs grow, the virtual servers can be simply adapted. You can rent a larger vServer at any time in case you need more working memory or hard drive capacity. No additional set-up fees are incurred when a larger vServer is ordered. Virtual servers are an excellent solution if you find that our webhosting fee is not sufficient but a dedicated server would be oversized. Vservers are ideal for test and development environments as well as for hosting multiple websites (e.g. of free-lancers or small companies). Even small online shops can be operated with them tanks to root access.

The counterpart is the root dedicated server. If you rent a dedicated server, you are the sole user of the hardware so that the full capacity of CPU, RAM and hard drive is available to you. For projects needing very large resources, dedicates servers are ideal and allow maximum server performance utilization. In addition, they can be put together individually for special applications and requirements. A small insight is given here.

The term rootDS is often encountered in connection with virtual servers. Don't let the name fool you, as it is not a dedicated server, but a virtual server too. Yet what is the difference between a virtual server and a rootDS? The difference lies in the type of virtualization. In fact, a Vserver with open VZ virtualization guarantees you only fixed size of disk space. However, there are no CPU cores reserved for you and often no guaranteed working memory because in a vServer, you share these system resources with other customers. A rootDS, on the other hand, ensures these resources for you exactly and comparably thanks to KVM virtualization. These ensured RAM and CPU are exclusively available to you. This form of virtual server is also known as virtual machine (VM).

At Keyweb, the smallest solution (RVS M14) has an open VZ virtualization, Nonetheless, this virtual server offers a few things because we guarantee you apart from 100 GB SSD disk space, already 1 GB working memory (RAM) and you only share the processor performance (CPU) with other customers. Our other virtual servers are characterized by rootDS systems in which we also guarantee you additionally an exclusive processor performance. Other virtual systems will never influence your system's hardware. If your applications need high system performance all the time, we recommend you one of the rootDS RVS S14, RVS L14 or RVS G14.

As you can see, we are optimally prepared to satisfy your individual needs and requests. Almost nothing is impossible. And always remember: There are no dumb questions! Just call us!
