Under normal circumstances, numerous websites can operate on each of the Virtual Private Servers, which are operated on the host machine. However, if in case, a single virtual server starts to hog a lot of resources of the host computer, then it can cause poor loading of web pages and other such service lagging issues. In this situation, a dedicated server is the only solution, offered by web hosting service, in order to deal with enormous traffic and work as per the needs.

Mirror and share a deep copy of your in and outbound virtual network traffic. Take advantage of aggregation, packet collection and load balancing solutions by streaming traffic to a destination IP endpoint or an internal load balancer in the same Virtual Network, peered Virtual Network or Network Virtual Appliance that you can deploy from a growing list of Security, Network and Application performance management partners.

Should you need more speed and performance you can also consider switching to an ssd-powered VPS package which has the same advantages as a VPS but offers faster performance due to the presence of SSD hard drives. VPS SSD is highly recommended for websites that use a lot of disk caching, for example WordPress websites with the w3 Total Cache plugin
The force driving server virtualization is similar to that which led to the development of time-sharing and multiprogramming in the past. Although the resources are still shared, as under the time-sharing model, virtualization provides a higher level of security, dependent on the type of virtualization used, as the individual virtual servers are mostly isolated from each other and may run their own full-fledged operating system which can be independently rebooted as a virtual instance.
