In the world of web hosting, there are many options for how to manage the computers that run a website, and it can be difficult to figure out what might be best for you. Since enterprise websites require the full resources of a server (or multiple servers) to ensure optimal performance for the site’s users, it’s important to make sure the best hosting option is chosen. When deciding upon those options, the choice often comes down to one of two possible approaches: dedicated or virtual hosting. Should you use your own physical server dedicated solely to you, or should you use a virtual server, which uses software to emulate a physical server on a virtual host? Let’s look at the pros and cons of each option:
In a dedicated hosting plan, a client leases or rents a physical server from a hosting provider. With Dedicated hosting plans, the client has complete control of the physical server and access to all its resources. This is a good fit for companies that have websites that expect a high amount of traffic, that are running intensive CPU applications, and that are hosting enterprise CMS sites.
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.[1]
