Yahoo Small Business services are intended and designed to meet the needs of personal and small business websites. This is why some of our plans offer unlimited disk-space, data transfer or email storage. It is not appropriate to use our services to support large enterprises or for levels of demand that impose undue burdens on our systems or negatively impact use by small, independently owned and operated businesses. If the bandwidth, data transfer or email storage of your website or email present a burden on the experience of other users or on our internal systems, we may, in our sole discretion, act to restrict the resources being consumed by your website, including by limiting how fast your disk space and email storage space can grow.
Cloud Hosting: Cloud hosting allows webmasters to tap into a large bank of servers that are all interlinked and designed to take over from each other if needed. In other words, if you need more resources, the cloud will provide more resources to rise to the demand. Cloud hosting is usually the best option if you want to aim for 100% uptime and don’t care how much you need to pay for it.
Some domain name registries, often called network information centers (NIC), also function as registrars to end-users. The major generic top-level domain registries, such as for the com, net, org, info domains and others, use a registry-registrar model consisting of hundreds of domain name registrars (see lists at ICANN or VeriSign). In this method of management, the registry only manages the domain name database and the relationship with the registrars. The registrants (users of a domain name) are customers of the registrar, in some cases through additional layers of resellers.
