The web hosting company will also provide regular web server software, installed programming language extensions, & firewall upgrades. Managed VPS plans running Windows normally include the use of Plesk for administration of domains and web server settings, while VPS plans running Ubuntu, Debian, Slackware, etc. can be administered using Webmin or Virtualmin under a free open source license.
Ultimately, it is used to decrease hardware costs by condensing a failover cluster to a single machine. Thus decreasing costs dramatically while providing the same services. Server roles and features are generally designed to operate in isolation. For example, Windows Server 2019 requires a certificate authority and a domain controller to exist on independent servers with independent instances of windows server. This is because additional roles and features adds areas of potential failure as well as adding visible security risks (placing a certificate authority on a domain controller poses the potential for root access to the root certificate). This directly motivates demand for virtual private servers in order to retain conflicting server roles and features on a single hosting machine. Also, the advent of virtual machine encrypted networks decreases pass-through risks that might have otherwise discouraged VPS usage as a legitimate hosting server.
Dedicated server hardware is also limited to a single tenant usage whereas VPS hardware is shared by multiple hosting customers on one partitioned web server. The latest trends in web hosting have seen companies move beyond the single server model on cloud, VPS, & shared platforms to host multiple copies of a website's files and use network load balancing software to route traffic to the hardware with the most open processing capacity for better response times.

With VPS Hosting, there are multiple instances of separate operating systems on a machine—thus giving you your own virtual private server. So while you still may be sharing a physical server at the data center, with your own virtual operating system, you’re able to have dedicated resources such as RAM, bandwidth, and disk space. In other words, the environment mimics having a dedicated server—at a lower cost!

VPS hosting is like you are living in an apartment complex. It means that other people are living in the same building, but you have your own secure apartment. You will get more room and restrictions will be fewer as compared to living in a dorm. It also means that if your neighbour is misbehaving, it is the problem of owner of building, not yours.

A virtual private server (VPS) is a cost-effective way for a small business to gain more flexibility and efficiency than is offered with shared hosting without the expense associated with running a dedicated server. Most small businesses also don’t need all the power of a dedicated server, so VPS provides a good in-between option when you outgrow your shared hosting. Get the power and flexibility of your own server without the cost and complexity of managing outsourced hardware.
Shared hosting is like you are living in a room with a lot of friends. It means you must fit in the same room and you must split the cost of several things because it is affordable and cheap. However, several individuals are sharing the same space, it means everyone needs to live within a space with restricted resources among them. You will have to use the same things (that sounds a little unhygienic).
Remember those times when the grass was greener, the light was brighter, and no one cared what you were doing on the Internet? Well, those times have passed. Nowadays, regional targeting, government censorship, and geoblocking restrict you from accessing the content you want. In addition, we hear news about another Internet privacy scandal almost every week. If you wish to browse freely and securely, a VPN server comes in handy.
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:
