Hosting:
Hosting renting server space from a host, you basically have two options - to rent shared server space or to rent a dedicated server. With a shared hosting arrangement (often referred to as 'virtual hosting'), your web-site shares server space with other web-sites. If you rent a dedicated server, on the other hand, you get an entire server and network connection to yourself.
Shared servers are less costly to rent than dedicated servers. They usually require a lower level of technical skills too, because the host does most of the server administration. This is why shared servers are usually the best choice for entry-level web-sites or for small businesses whose web-sites do not have high traffic levels click here.
While shared servers are the most cost-effective option for small web-sites, they are not necessarily a good option for large, "mission-critical" or high-traffic web-sites. For these a dedicated server may well be necessary Web Development.
Dedicated servers are more expensive to rent than shared servers, and they also require a higher level of technical skill to operate. However, if you are making thousands of $$ a day from e-commerce and your business would fail if the server went down for a day or more, then you should seriously consider renting a dedicated server.
