There are several differences between Cloud and VPS Servers. In VPS, one dedicated server is partitioned into several servers that are virtualized further to make each of them work as a dedicated server. In cloud, the client rents a small part of a huge network of connected machines. This setup offers connected resources that are rented out to the clients who can easily scale them up with a few clicks of the mouse as per their requirements. In VPS, if the machine or any of its parts fails, the VPS goes down.
In cloud, the system is rerouted to another available resource, which means negligible downtime. VPS offers a virtual environment with a certain bandwidth and a portion of disk space, with the memory and CPU of the parent machine equally distributed among all the VPS clients. However, in cloud, the client is completely separated from all the others. And so, it offers a much safer environment than VPS. A VPS offers the choice of just one operating system while the cloud gives the client the freedom to choose any operating system they want. They can even install or replace any operating system from the choices available with cloud.
Most CentOS VPS Hosting providers offer customizable hosting accounts to clients where they can easily choose the amount of RAM, data transfer, and disk space they require. They don\'t have to pay for those resources that they won\'t use. If they seek a resize of their VPS, they can easily contact the support team of the provider. Some service providers also guarantee 99.9% uptime.
