Stability - Unlike shared hosting, the traffic and activities of other VPS customers will not adversely affect your operation.
Performance – Having your own allotment of resources allows you and your visitors to enjoy faster load times.
Dedicated Resources – VPS hosting provides you with more disk space, CPU and RAM.

 

A VPS is basically a server running within a server. One physical server hosts multiple virtual servers, each isolated from the others. This is accomplished with software, called a hypervisor, that segments the physical server and keeps each segment separate from the rest.

 

It helps in improving the performance of high-traffic websites. If you have hosted your website on a shared server but aren't able to cope up with the resources then VPS hosting is the best for you. VPS hosting is required because: VPS offers dedicated server environment at a low cost as compared to dedicated server.

 

There are applications such as Auto Trading System which is if installed and setup on VPS then you need not to worry about power failure or internet disconnectivity.

You can shutdown your local machine and Auto Trading System will keep working on VPS.

Apart from that, there are many buy/sell indicators which work on desktop / laptop applications but do not work on mobile applications. For those persons who have to travel and can't stick to desktop / laptop during trading hours, You can setup those indicators on VPS and can access them through mobile.
