A middle-of-the-road solution between dedicated servers and shared hosting is a balance that makes a lot of sense for many businesses. Such a service exists and is called a virtual private server (or VPS). VPS offers webmasters a way to host their own server, but without the higher costs and complexities of dedicated servers. Here’s more about whether VPS strikes the right balance for you.
When a website uses shared hosting, it shares memory, hard drive space and CPU cycles with other sites on the same server. If one site gets hacked, there is a chance that other sites on the same server can get hacked. If one webmaster uses up all the server resources, other sites on the same server suffer. Some web hosts place hundreds of sites on the same server, so each site is at the mercy of other webmasters.
