WordPress Multisite networks enable management of many WordPress sites from a single dashboard. These can be configured as domains names that are completely distinct from one another or as subdomains or as directories on the original website. As you can imagine, this is extremely cost-effective for implementing several sites (we manage networks of more than 50 sites) because the primary WordPress web design is completed only once. The rest of the WordPress designs can be derived from the first one and made to look as similar or as different as desired.
Magento has a similar system that allows administration of multiple stores from a common administrative interface. Both systems allow sites to share design elements and functionality, which simplifies management and decreases development costs.
