To start your own cloud hosting you have to create a clustered of couple of servers. Cloud server is basically virtual servers pull their computing resource from extensive underlying networks of physical web servers.
CloudLinux don’t act as cloud server. It’s operating system which is essentially a set of kernel modifications to the Linux/Centos. Its features to enable administrators to control of their server’s resource use like as inode,CPU and memory.
Cloudlinux is a modified version of CentOS and is an operating system created to work on one server instance. It has nothing to do with the Cloud, although that it is a very useful software to reduce the resource usage on a certain virtual hosting (Shared Hosting) account. If one needs to have a cloud setup, they must create a networking model of a computer system where the storage and processing operations are delivered from separate appliances.
