Thanks to a hypervisor, a guest OS does not ‘know’ about other virtual machines on a bare-metal server. Like that frog who lives in the well thinking he is in the ocean, a virtual machine ‘believes’ that it is a physical server. In this case, theuser can have root access to a VPS and control its software. Additionally, if we decide to upgrade something or change a physical machine altogether, we do not need to make changes in a guest OS. Let’s get a closer look at advantages of VPS hosting.

Operating System virtualization refers primarily to Type-2 hypervisors like KVM or platforms like OpenVZ & Virtuozzo that share the Linux kernel (+ drivers) between partitions on the same web server hardware. This form of VPS is common in managed cloud plans where the web hosting company provides a custom web server stack software such as LAMP/LEMP pre-installed on a VM partition. Multiple customers can share a single dedicated or rackmount server with better security, file isolation, database, and programming language extension support than shared hosting provides, as well as having access to a higher level of web server resources when processing scripts like PHP, Python, or Node.js code. Some forms of OS virtualization will also permit Windows, Linux, & BSD to be installed on the same physical hardware.
VPS installation on SSD storage is much faster than HDD, where managed platforms offer a pre-installed partition available instantly after sign-up for a new hosting account and some "bare metal" partitions take longer to create. Unmanaged plans usually require the customer to install the operating system and web server stack software on a VPS plan personally. Cloud VPS plans offer snapshot services like Bitnami that can speed up web server installation and CMS application deployment considerably. Beginners will prefer managed VPS plans with CentOS and cPanel for a near identical user experience for multi-domain management as on shared Linux hosting plans.
We’ve recommended InMotion’s Business Hosting Plans for many years now. However, their VPS Hosting plans take things to another level. First of all, with InMotion Hosting’s VPS you get real-time redundancy—meaning, if there is an issue with your server, your website will be available almost instantly on another server in the cluster. This high availability feature is powered by a cloud infrastructure. The combination of VPS and cloud hosting benefits make InMotion Hosting one of our top picks. But, you actually get much more with their VPS Hosting plans.

For most purposes, a virtual private server is similar to a physical server and since they are software-defined, they can be more easily configured and created.
So that’s it, then – a VPS is for everything in between, right? Well, yes…and no. A VPS (Virtual Private Server) is a flexible solution that falls in between shared and dedicated hosting, not only in price but also in the way it functions. Like a dedicated server, a site hosted on a VPS gets its own RAM and disk space; however, like a shared server, it uses the same processing capacity (CPU) as a certain number of other sites. So, while your site’s performance isn’t reliant on shared RAM and disk space, it is dependent on a shared processor. Moreover, the distribution of processor share varies from provider to provider.  The table below shows how most hosting companies break down the differences between shared, VPS, and dedicated hosting plans:
