If your website exceeds the resources of a shared hosting plan (perhaps you’ve seen higher levels of traffic), the natural next step is a virtual private server (VPS) hosting plan. A VPS hosting plan will get you increased performance and larger resource allocations without saddling you with the full cost of your own server.
VPS plans are similar to shared plans in that both feature multiple websites hosted on a single server. However, VPS plans maintain a strict separation between clients and websites when it comes to resource allocations. Your site gets its share, and no one else may use your resources (conversely, you may not cannibalize the resources allocated to others’ websites either).
In addition to providing you with greater performance and larger resource allocations, VPS hosting gets you full control of your server environment. Though a VPS is not a physical server, you can control it as if it were.
If you have special needs for your server, you have the control to address them. With that said, you’ll need to have some degree of comfort with server technology to manage a VPS. This is typically done using the command line, though you can opt to purchase a GUI-based control panel, like cPanel or WHM, for ease of use.
