Virtual Private Server Hosting or VPS Hosting is essentially a dedicated server within a shared hosting environment. With VPS Hosting, each customer can run their own virtualized operating system within a partition of a dedicated server. Even though multiple customers are on the same physical machine, VPS Hosting allows each customer's account/website to have all the capabilities of being on their own separate machine. This type of hosting offers advanced performance and flexibility with the ability to customize at an affordable price.
If you’re outgrowing your shared web hosting or simply want more control, a managed or fully managed Virtual Private Server (VPS) is the next logical choice for your hosting needs. It gives you more freedom with root access to Apache and PHP, plus you can install an SSL certificate, as well as any type of software – all without the responsibility of a dedicated server.
A VPS runs its own copy of an operating system (OS), and customers may have superuser-level access to that operating system instance, so they 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. However, as they share the underlying physical hardware with other VPSes, performance may be lower, depending on the workload of any other executing virtual machines.
