If you have an adequate budget, then some of the reasons why you should opt for a dedicated hosting over shared hosting are-

1.) Server resources are not shared- All the resources (CPU, RAM, storage, bandwidth) on the server are solely for your use.

2.) Enhanced performance- Due to high availability of resources, maximum uptime for your website is guaranteed with dedicated hosting.

3.) Rigid Security- As the server is isolated, dedicated hosting provides enhanced security, particularly necessary for organizations handling sensitive transactions over SSL or FTP.

4.) Root access- You get more control over your server as you have the freedom to customize and install applications or software depending on your needs.

However, these advantages come at a premium. Shared hosting is the cheapest option for a business to run it’s website online, and dedicated hosting is more expensive in comparison. But websites which deal with a lot of traffic, or have strict requirements for customization and security, may find dedicated hosting as the best option.
