First, VPS is a complete virtual server that is reserved for you, which means that it has resources reserved for you and does not share it with other sites,
When you buy a shared hosting, that is, hosts known to all of these, you actually buy a part of the server that you share with other website owners than you, so one of the disadvantages of shared hosting is the bad neighbor, You can consume server resources in a way that affects your neighbors using the same Server users, things are still complicated right? Keep reading then.
When a hosting company, such as FastComet, BlueHost or others, installs a new server in order to sell it as hosts, it does not fully reserve it as a single server and then sells it as shared hosts to several subscribers, this server has unique specifications and they can benefit from it better than this, so they install Virtual Servers, which means that this original server is installed on 10 or 20 virtual servers or more, then these virtual servers are sold as shared hosts or VPS to a person.
Suppose you want to sell one of the virtual servers as shared hosts, you can host several accounts (subscriptions) on one server, each of them pays about $ 5 per month to get a share of this server, and they subscribe to the resources of this virtual server between them (the default server has specific resources that it does not share with another virtual server on the same original server).
Then, a person comes with a huge site, and has tens of thousands of daily visits, this site cannot be hosted in a shared hosting, this will cause a problem for him and the neighbors of the server, therefore, he can buy a Full virtual VPS server to put your site on it, and in this case the resources are available for this. The server is completely reserved for one person.
What are the uses of VPS servers?
The VPS server can be used to run many systems such as Windows-Linux and other systems.
Software engineers and designers use it to create, production and test projects and games they make.
A few programmers use it for robbery and theft, in light of the fact that the virtual server is hard to follow through government organizations since it contains heavenly security and encryption frameworks.
