If you are people who like to investigate and investigate all the uses that a PC can have, as well as the vulnerabilities and others that they can present, then this topic will not be new, but for those of you who didn’t know him. we will discover the world which is one virtual machine, as well as some uses you can give it. And when it comes to testing, it’s always best to use a device that can’t be broken.
Virtualized devices offer many advantages: in the home environment we can use them to learn, but their use also extends to the professional environment thanks to various applications that allow us to create different virtualized environments within the same hardware . In this way, virtualization offers us everything from the possibility of testing with different operating systems at home to the possibility of configuring different virtual servers within a physical server.
What is a VM?
When we talk about virtual machine, we refer to a type of software that simulates the hardware of a computer, technically what it does is to virtualize, as the name suggests, the resources that our system has to create (literally) a computer in another computer. There are several types of software that we can use for this, but generally for testing at home or at an educational level, VirtualBox is usually used, since it is a free application.
On the other hand, virtualization also has business utility as we stated previously, and in many cases for certain types of operations it is better to use a virtualized server within a server that contains many resources, because this allows these resources to be divided. to optimize them as much as possible. We can give a very simple example, let’s imagine you have a very basic server that has 32 GB of RAM, a 16 core processor and 400 GB of space, in this case we could create 3 virtualized servers that use each a quarter of the original system resources, so instead of having a single very powerful server, we would have four lower powered ones.
For some people this may seem silly because we may think that the more powerful a server is, the better, but in some cases this is not the case, because if we have installed a service that does not consume a lot of resources, then we’re using an excessive amount of hardware for something that doesn’t even need a quarter of it to run as efficiently as possible.
What is a virtual machine used for?
There are many reasons why we may want to use a virtual machine, since by being able to replicate the power of a computer, we can use them, for example, to test new versions of certain operating systems. If we have very powerful hardware, we can also use this type of virtual computers to test applications that we do not trust too much, since we can configure them Machinery so that they have no connection, which allows us to prevent, if an application contains a virus, from being transmitted to our network.
But as we have explained well, there are many uses that we can give to a virtual machinesince ultimately everything depends on our imagination, and taking into account that if we break it we will simply have to reinstall the machine, or simply delete it and upload a new one, we can get rid of the fear of thinking that we might end up destroying something important. So if you want to try to see what happens if we manage to delete the System 32 folder in a Windows operating system, or the root folder in a Linux operating system, you can always use this type of software.
