Disadvantages Of Virtual Private Server (VPS) Web Hosting

Not all providers setup or define Virtual Private Servers, also known as Virtual Dedicated Servers, the exact same way. You must ensure that your provider guarantees that their setup is robust enough to handle operations at a peak level. A ploy used by some providers in the reselling and shared space is 'overselling'. What this means is selling more in terms of services than what physically available, with the hope that the end users wouldn't use up all the service that were advertised to them. In the realm of VPS this can be a bit more serious, since at least the expectation is that you are operating in a more robust environment and many clients could be running more intensive applications like message boards or custom web applications. A shortfall of resources could end up resulting in problems for everyone hosted on such a server, therefore negating the benefits of a VPS. In a shared or dedicated environment you may be able to access more resources during peak or spike periods but since the VPS environment limits you to your slice of the server resources, it can be a drawback.
