If your site is too large for shared hosting but too small for the dedicated hosting server, VPS may be the right solution for you.
VPS stands for Virtual Private Server or Private Virtual Server and is a type of hosting that you will find if you exceed a basic shared hosting plan. VPS offers a partially isolated environment along with greater control and the ability to do more advanced things with your website. The space on the server is divided into containers, and those standalone servers are less risk-prone.
To better understand VPS hosting, you must first understand what hosts both a dedicated server and VPS. A dedicated server offers privacy, security and dedicated resources. you do not have to compete with other web sites for bandwidth, speed and storage space. It's like saying your own little private island in the ocean for lodging.
A VPS creates an environment similar to that of a dedicated server, but in a shared hosting situation. In other words, you're still sharing the physical server with other publishers, but it does have some private space within that shared space. So if you are sharing an island with other natives, but your area is separate from the others.
Why use a VPS?
Most beginner website owners start with a shared hosting plan. Shared hosting is designed for small sites that do not require too much. Once your site grows, it is likely that a VPS server will be needed for the next step.
The important part of VPS is virtualization. The host divides a server into several smaller virtual servers, each with its own piece of RAM and hard disk space. When a customer purchases one of these virtual servers, they enjoy a more isolated experience, since their virtual server can not be interrupted by other clients. (Note that you still share some things with your hosting clients.)
VPS is ideal for small businesses that want a little peace of mind and are willing to pay for it. If you need to know that your website will not be dragged by a bad neighbor, a VPS will be worth the extra expense.
