Whois & Analysis for virtualhosting.hk

Cloud computing is a type of Internet-based computing that provides shared computer processing resources and data to computers and other devices on demand.

It is a model for enabling ubiquitous, on-demand access to a shared pool of configurable computing resources (e.g., computer networks, servers, storage, applications and services), which can be rapidly provisioned and released with minimal management effort.

Cloud computing and storage solutions provide users and enterprises with various capabilities to store and process their data in either privately owned, or third-party data centers that may be located far from the user–ranging in distance from across a city to across the world.

Cloud computing relies on sharing of resources to achieve coherence and economy of scale, similar to a utility (like the electricity grid) over an electricity network.

The Internet is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link devices worldwide.

It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies.

The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and peer-to-peer networks for file sharing.

A content delivery network or content distribution network (CDN) is a globally distributed network of proxy servers deployed in multiple data centers.

The goal of a CDN is to serve content to end-users with high availability and high performance.

CDNs serve a large fraction of the Internet content today, including web objects (text, graphics and scripts), downloadable objects (media files, software, documents), applications (e-commerce, portals), live streaming media, on-demand streaming media, and social networks.

An email hosting service is an Internet hosting service that operates email servers.

Email hosting services usually offer premium email at a cost as opposed to advertisement-supported free email or free webmail.

Email hosting services thus differ from typical end-user email providers such as webmail sites.

They cater mostly to demanding email users and small and medium-sized (SME) businesses, while larger enterprises usually run their own email hosting service on their own equipment using software such as Microsoft Exchange or Postfix.

Hosting providers can manage a user's own domain name, including any email authentication scheme that the domain owner wishes to enforce in order to convey the meaning that using a specific domain name identifies and qualifies email senders.

Technical support (often shortened to tech support) refers to a plethora of services by which enterprises provide assistance to users of technology products such as mobile phones, televisions, computers, software products or other informatic, electronic or mechanical goods.

In general, technical support services address specific problems with a product or service rather than the provision of training, customization, or other support services.
