VPS or Dedicated Server

The answer really depends on your hosting needs. But if you want more stable hosting, then I suggest you to go for dedicated hosting, since in dedicated server all the resources (i.e. memory, hard drive, Ram, Processing power) are dedicated to the single customer. Whereas in case of VPS, several servers will share the single server. Hence speed and Stability of the VPS also vary from company to company, since if the host node contains more Virtual machine then the VPS will be slow. That's why it is important, if you are looking for VPS hosting Hosting. Please always looks for a reliable VPS provider with 24X7 support and nearly 100% uptime.

So if you are looking for good performance, I recommend you to look for Dedicated server.

My opinion is Dedicated server. I'm using Offshore SEO VPS a long time. They have really good online chat service may help you with any question. Take a look their site. Strongly recommended.
