Note that I have included tests from some reputable DNS blacklists - these can make a big difference to server load. Barracuda requires you to register your IP address. Note also that I have enabled memcached to avoid a problem with "unable to get exclusive lock" errors in the mail log. Memcache is also useful for caching plugins like W3 Total Cache in WordPress.

Similarly, in a real dedicated server, you will pay for the entire server that is not shared with anyone else. You will get complete control over all services. Unfortunately, it is also the most expensive hosting option and needs some technical expertise to manage. It is commonly used by those who have websites with specific scenarios, most commonly extremely high traffic and tight security requirements.
Shared: To begin with, both VPS and Shared Hosting host multiple tenants on a single server. However, there is one key difference: In Shared Hosting, the resources are spread equally between all users. As a result, the bandwidth for users of Shared Hosting will fluctuate based on need and you won’t be able to control the bandwidth you receive. On the other hand, VPS is a more customised option – you can select a plan and provider that gives you access to the maximum amount of RAM, server space and bandwidth. From the first step, VPS puts the reins in your hands.
The most obvious and popular reason for a VPS is to run a single website, or multiple websites. However, you can use them for pretty much anything that requires access to the internet – such as a web application like Nextcloud to run your own Dropbox alternative – or to create your own virtual private network to better secure the internet connection of your PCs and mobile devices.
