A VPS runs its own copy of an operating system, and customers have superuser-level access to that operating system instance, so can install almost any software that runs on that OS. For many purposes they are functionally equivalent to a dedicated physical server, and being software defined are able to be much more easily created and configured. They are priced much lower than an equivalent physical server, but as they share the underlying physical hardware with other VPSs, the performance may be less, and may depend on the workload of other instances on the same hardware node.
What is VPS hosting? Basically,VPS hosting (Virtual Private Server hosting) is a service that gives you a web serverâ€™s hardware to share with others without sharing the software. This means that you can have complete root control over the server as if it was your own dedicated server but you will still share the CPU, RAM, and bandwidth with other users. You can still have guaranteed CPU, disk space, and memory. This means you can install whatever you want.
VPS hosting is more expensive than shared web hosting but it can be far less expensive than dedicated hosting while giving you some of the same benefits. Wikipedia says this about "what is shared VPS hosting?": "A virtual private server is a method of partitioning a physical server computer into multiple servers such that each has the appearance and capabilities of running on its own dedicated machine. Each virtual server can run its own fullfledged operating system, and each server can be independently rebooted."

You can install a custom Apache module or try out a new programming language. You can get in a and make detailed changes using the command line or remote desktop but your hosting company still usually makes it easy to administer your site using a Virtualization control panel such as Virtuozzo Power Panel.

What is VPS hosting not good for?
More responsibility. You have to keep the system up to date and running with linux VPS. If the web server software comes out with a new version to fix a security problem, you have to update it so your server doesnâ€™t get hacked. If the web server software crashes over the weekend, guess who gets to fix it? That would be you, my friend, not the friendly administrator who handles the shared web hosting servers. Fewer resources than dedicated. Though you get a certain portion of the serverâ€™s hardware, there are far fewer resources than if you had your own dedicated server.
Risks. Your hosting company may not issue you with your own IP address, and thus may be sharing yours with other less scrupulous tenants. Since hosted sites on the same IP addresses are sometimes grouped together this may result in your site being banned from search engines that are actively seeking to remove such sites. Control. Under some VPS platforms users share software components. This sharing may result in an inability to configure individual settings independently of other clients that are hosting on the same virtual server. With Ideastack hosting,
