VPS hosting assures a fixed level of performance because a guaranteed level of system resources is dedicated to your virtual server. However, high demand by your server or another virtual server on the same physical host may impact performance if you both need the extra resources at the same time, or if your server needs more than the physical host can provide.
Let's say that you, for example, use a regular shared server instead of cloud hosting. One physical server has all of your data and them, just like that, it's down or even completely wiped out. Issues in one shared server account can cause troubles to the other sites on the same physical server. Usually, that's downtimes and file loss! You only use one server for shared hosting. When someone hacks it - it’s bad news.
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.
