What are the benefits of virtualization

Advantages and disadvantages of virtualization

Today I have something special for you! Today I am dealing with the advantages and disadvantages of server virtualization. Although the technology has been on the market for almost 10 years, it is still considered "new". But before you jump on the new investment, you should keep these advantages and disadvantages in mind.


1. Power saving

Maybe just a small one, but at least: Fewer physical machines in a data center simply mean less consumption and less heat. You don't have to be an environmental fanatic right away. A cool data center is always sufficient here.

2. Smaller data centers

Of course, fewer physical machines also mean more floor space and less cabling. Of course, only if you ignore the future enlargement of the server landscape. Because there is more space available, more can be done within the data center. More servers to expand your virtualization environment.

3. Own test environment

Virtualization set up and still free servers available? Perfect for your own test environment! Here you can try out applications and tools in peace and without additional costs. In addition, virtual machines could be made available for tests and developments. You don't want to break your own system right away.

4. Faster server provisioning

The easy and fast installation of virtual machines means that there are no cumbersome and time-consuming inquiries for a new server. Everything takes just minutes today.

5. Extend the life of old applications

Everyone, whether company or private person, still has old applications. Either developed in-house or purchased, but these no longer run on current operating systems or require special hardware. These applications can easily be packaged in a virtual machine and, if necessary, simply pretend the required hardware.

6. Last but not least: the cloud

If you haven't heard of the term, here is a short definition from ENISA:

"Cloud computing is a model that allows you to conveniently access a shared pool of configurable computer resources (e.g. networks, servers, storage systems, applications and services) via a network at any time and anywhere - quickly and with minimal management effort or little service provider interaction can be made available. "

Of course, you still have to differentiate between “private cloud” and “public cloud”. With the “private cloud”, the infrastructure is operated and managed by only one institution. With the “public cloud”, access for large groups is guaranteed.
