VPS and cloud computing are not mutually exclusive options. You can host your VPS in a virtualized environment. This allows you to convert one physical server into multiple virtual machines, each of which acts like a unique physical device for running both IT resources and web applications in a flexible, instantly scalable and cost-efficient manner.
VPS hosting has a limit to scaling depending on the physical host machine. You have access to some extra memory and CPU power above and beyond the amount dedicated to your virtual machine, but the physical host has a fixed amount that it can deliver. If you need more, you will have to get a new plan and may experience downtime while you migrate to a new solution.
Cloud hosting automatically distributes three mirrored copies of your data across multiple devices to ensure safety and redundancy. Additionally, HostGator employs a number of security measures to protect our servers and customers' websites. Our data centers are built using top-of-the-line technology, and servers are monitored 24/7 in a highly secure environment.
