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?
