Domain Names are web addresses, identification labels which defines an administrative autonomy, authority, or control in the Internet.

A Domain name is also hostname which identifies Internet Protocol (IP) resources such as web sites. Domain names are formed by the rules and procedures of the Domain Name System (DNS). They are used in various networking contexts and application-specific naming and addressing purposes. Domains are organized in subordinate levels (subdomains) of the DNS root domain, which is nameless.

The first-level set of domain names are the Top-level domains (TLDs), including the generic top-level domains (gTLDs), such as .COM, .NET and .ORG, and the country code Top-level domains (ccTLDs).

There are second-level and third-level domain names in the DNS hierarchy which are open for reservation by end-users as well.

Cloud Hosting is a Internet hosting service delivered from a Cloud computing generation IT infrastructure. Cloud computing term generally refers to a systems which combine the computing resources of a number of machines in order to provide High Availability, ability to scale up and down the services and more flexibility to the users.

The term Cloud Hosting can be also associated with another one – Clustered hosting. Despite that as of May 2011 the term Cloud Hosting is pretty broad term which is not precisely defined yet, we can consider any hosting service as a “Cloud” if it is delivered from a fully-redundant, multi-server system, in which the resources are dynamically scalable and often virtualized.
