What is the difference between a virtual private server (VPS) and a semi-dedicated server? Are these servers one and the same? Not exactly. Yes, both have been touted as the best stopover between shared hosting and dedicated hosting. Personally, I will go for VPS hosting. I may not own the physical server here but I definitely have control over its virtual pieces. In terms of security too, VPS hosting assures me more. In a semi-dedicated server, you continue to share the physical server with other websites, only this time you share it with just a few.
OK, let me explain the difference between the servers by understanding what each is.
Virtual Private Server (VPS)
A physical server is partitioned into logical partitions and each of the partition becomes a VPS. Now, one virtual server does not interfere with another. You get complete control on them. You can configure them according to your own specifications. You don’t have to share your virtual server with other websites.
Unlike a dedicated server, you don’t own the semi-dedicated server. The hosting company owns it. This server behaves like a shared server in the sense that you share it with other websites. However, this time your share is better as you share the server with a handful of websites. You get root access and control over a part of the server.
Many would say a semi-dedicated server is better because you get a better and bigger share with it. On the other hand, you can get many virtual servers and work with them. The choice between the two depends completely on your needs.
