E-commerce web hosting is the technology of storing, servicing and maintaining files for one or more web sites selling products or services online. Web site owners who pay for a web host (generally on a monthly basis) upload their web pages to a shared or dedicated web server through an ISP (internet service provider). The web host should ensure a fast and consistent connection. Experienced web entrepreneurs desire flexibility, security and high performance from an e-commerce host. An e-commerce web server also stores information, images, videos and just about any other content that can be retrieved from a web site. Security is a priority for e-commerce web servers.

E-commerce web hosting can be divided into two major components, the site and the host (where the site is stored for access on the web). Web hosts are computers that offer storage space and Internet connectivity. Web hosts make your web site work with and connect to the Internet. E-commerce, or web commerce, allows people to buy goods and services online. On the Internet, one can buy almost anything, at any time.
