All of the sites under your reseller account are also logically isolated using Cloud Linux, which means that one site cannot affect another if for any reason it's compromised or has any other problems. The other use case is for other web professionals that may have lots of developed websites, and are looking for a way to host them economically without worrying about server management and backups and so on. This is perfect for web design or web development agencies who are happy to manage the web space for their clients, and it means you can often 'jump in' and fix and help with issues your clients might be having with your reseller access, saving time because you're not needing to ask them for logins and so on. Perhaps this could be to friends and family, or on a professional basis it could be to sell to your clients as a way to generate recurring revenue. The first and most obvious case, is for a person or company that wants to 'Re-sell' hosting space - so you get given a certain amount of resources and maximum accounts, and you can divide this up and sell hosting space to your clients. Reseller hosting is a great option for several use cases.
