VPS hosting is slightly similar to shared hosting in a sense that multiple people are hosting their sites on the same physical server. The users also share internet bandwidth capacity and hardware. Even with these similarities, this type of hosting is quite different from shared hosting in many ways. When you use a virtual private server (VPS) you get your own portion of the server which is partitioned from everyone else. Basically you could imagine it as many small servers on a single larger server. The advantage is that all of the users will be able to get similar benefits to that of a dedicated server but they will not be paying such a high cost for their hosting. In addition to getting your own file system and operating system, you will also enjoy the benefit of having root access. One of the things that causes people to switch to a virtual private server is the amount of control that is available. You have the ability to host as many websites as you want as well as install your chosen software without having to anticipate performance issues. Plus, you can reboot the server whenever you want to without having to get permission beforehand.
You can get tighter security and reliable performance in a cost effective manner with VPS hosting. If you do not have the funds to pay for a dedicated server but you need to upgrade from shared hosting, this is the perfect solution for you. Plus, since everyone wants VPS right now and it is in high demand, the prices are very reasonable. With a VPS package you will get a platform and operating system that is totally isolated, so your resources like CPU and RAM are going to be reserved and only usable by you, as well as the memory and hard drive space.
There are some websites that may be able to always get by just fine with shared hosting. If you have any plans for your business to grow to the point where your site is getting a lot of traffic you will most likely discover that once you succeed in driving traffic to your site you can no longer get by on shared hosting. If you prefer not to make a big investment but you need to do better than shared hosting, you will find an ideal solution in VPS hosting.
