These change all the time. Used to be (earlier days) you could even get free hosting. Now you pay.
There are many levels of doing this. There is the small business - mom&pop - type store that will have low traffic. However, this does not mean they don't need solutions for sales, security and dynamic content. Then there are the large sites - like Amazon, Ebay ,etc. There needs are much more complex and involve a large number of type of systems. This page does not address those needs. However, there are some larger companies and mid-size companies that have choosen some form of hosting solutions rather than owning all equipment and services themselfs. So "hosting solutions" are not just for small companies ----but, they come in very different forms (like Amazon Services).
Small Business Hosting Solutions:
Some of these hosting solutions provide WYSWIG editors that you use to create pages hosted on their servers. Others let you upload your own created pages.
