Dedicated hosting can be very advantageous for certain websites and applications. First of all dedicated servers are one of the most secure hosting options. The simple fact that you won’t be sharing a server with other sites that might be vulnerable to hacking is a big plus.
Dedicated servers also tend to have higher uptime, as there are less hardware and software failures that may result in your site being taken down.
Dedicated servers are also optimized for performance and uniquely structured to address your unique website needs. Your site will be able to utilize the full resources of the server without having to share them or compete for them, with other websites.
Finally, dedicated servers also provide you with scalability to meet the changing needs of your website. This style of hosting environment has larger resource allocation abilities, plus additional servers can be brought on if you exceed those resources.
