Server virtualisation - Powerful rack servers as VMs bring many advantages
Simply because the respective servers sometimes have very different requirements in terms of configuration, it is not a good idea to run several different services on one device. This is also because - in the event of a hacker attack, outage or other malfunction or emergency in which a server ‘crashes’ - not just one application but several are paralysed. And this does not make recovery any less complicated. But if you need to make savings in terms of hardware and running costs and want to combine similar services, you can rely on server virtualisation - that's what today's blog post is all about.
Are virtual machines also worthwhile for SMEs?
Virtual servers are by no means just for large companies - SMEs can also reap many benefits from this technology. The common rule of ‘one server per service’ can be circumvented with VMs. As already mentioned, it is very tempting to install other applications on the racks that have a low utilisation rate. However, server consolidation should only be achieved through virtualisation. Although various functions and services can be provided via one platform (hardware-based server), they are still separated by the individually installed VMs (software-based server). The hardware basis is called the host, the virtual servers are called VMs or guests. Each individual VM also requires its own operating system - a kind of ‘intermediary’ is also required between the hardware and software, i.e. virtualisation software such as VMware or Hyper-V.
