Plus, other users on the physical server won’t have access to your VPS setup. On a shared host, it’s possible for a malicious user to hack the host and access other user accounts on the server being shared. Since virtual private servers exist in a sandbox, other users can’t access your virtual environment unless they obtain your account login information.

Once you register your website's domain name, it's time to start picking the specs for your server. Web hosts typically offer multiple VPS plans that have varying amounts of email capability, RAM, storage, CPU power, domain hosting, and monthly data transfers. The plans typically include website builders that let you quickly create a face for your site without much—or even any—coding required. A solid web host should offer at least 4GB of RAM, 100GB of storage, and an ample volume of monthly data transfers. If you expect a significant amount of website growth, then you should look for a web host that has as many unlimited offerings as possible. For example, Hostwinds—the PCMag Editors' Choice for VPS hosting—offers unlimited email, domains, and monthly data transfers. Note, however, that as with all unlimited service offerings, you really need to read the fine print to make sure that what you mean by unlimited and what the hosting service means by it.
VPS has a dedicated IP address, which you do not have to share with other users. This is important, as in shared hosting many domains are under one IP address and if one website fails, the whole IP address is added to the blacklist. Also, in case of shared hosting, your website's load can be affected by another user on the same server. It means that if your "neighbor" website is loading or it is inaccessible for various reasons, your website loading time can be increased too.

Partitioning a single server to appear as multiple servers has been increasingly common on microcomputers since the launch of VMware ESX Server in 2001. The physical server typically runs a hypervisor which is tasked with creating, releasing, and managing the resources of "guest" operating systems, or virtual machines. These guest operating systems are allocated a share of resources of the physical server, typically in a manner in which the guest is not aware of any other physical resources save for those allocated to it by the hypervisor. As a VPS runs its own copy of its operating system, customers have superuser-level access to that operating system instance, and can install almost any software that runs on the OS; however, due to the number of virtualization clients typically running on a single machine, a VPS generally has limited processor time, RAM, and disk space.[citation needed]
