Cloud computing

Cloud computing depends on offering of assets to attain soundness and economies of scale, like an utility over a system. At the establishment of Cloud computing is the more extensive idea of met framework and imparted administrations. 

Cloud computing, or in more straightforward shorthand simply the cloud, additionally concentrates on boosting the adequacy of the imparted assets. Cloud assets are normally imparted by various clients as well as alterably reallocated for every interest. This can work for assigning assets to clients. For instance, a cloud machine office that serves European clients amid European business hours with a particular application may reallocate the same assets to serve North American clients amid North America's business hours with an alternate application. This methodology ought to amplify the utilization of figuring power accordingly decreasing ecological harm also since less power, cooling, rackspace, and so on are needed for an assortment of capacities. With Cloud computing, various clients can get to a solitary server to recover and overhaul their information without obtaining licenses for diverse applications. 

The expression "moving to cloud" additionally alludes to an association moving far from a customary CAPEX model to the OPEX model. 

Advocates assert that Cloud computing permits organizations to dodge forthright framework expenses, and concentrate on ventures that separate their organizations rather than on base. Defenders additionally guarantee that Cloud computing permits undertakings to get their applications up and running speedier, with enhanced reasonability and less upkeep, and empowers IT to all the more quickly change assets to meet fluctuating and eccentric business request. Cloud suppliers commonly utilize a pay as you go model. This can prompt suddenly high charges if chairmen don't adjust to the cloud estimating model. 

The present accessibility of high-limit systems, minimal effort machines and capacity gadgets and additionally the boundless reception of equipment virtualization, administration arranged building design, and autonomic and utility figuring have prompted a development in Cloud computing.

Server

In most common use, a server is a physical computer dedicated to run one or more services, to serve the needs of the users of other computers on a network. Depending on the computing service that it offers it could be a database server, file server, mail server, print server, web server, gaming server, or some other kind of server.

In the context of client-server architecture, a server is a computer program running to serve the requests of other programs, the "clients". Thus, the server performs some computational task on behalf of "clients." The clients either run on the same computer, or they connect through the network. In the context of Internet Protocol (IP) networking, a server is a program that operates as a socket listener. Servers often provide essential services across a network, either to private users inside a large organization or to public users via the Internet.

A network server is a computer designed to process requests and deliver data to other computers over a local network or the Internet. Network servers typically are configured with additional processing, memory and storage capacity to handle the load of servicing clients. Common types of network servers include: Web servers, proxy servers, FTP servers, online game servers

Numerous systems use this client / server networking model including Web sites and email services. An alternative model, peer-to-peer networking enables all computers to act as either a server or client as needed.

Servidor

En informática, un servidor es una computadora que, formando parte de una red, provee servicios a otras computadoras denominadas clientes.1
También se suele denominar con la palabra servidor a:
Una aplicación informática o programa que realiza algunas tareas en beneficio de otras aplicaciones llamadas clientes. Algunos servicios habituales son los servicios de archivos, que permiten a los usuarios almacenar y acceder a los archivos de una computadora y los servicios de aplicaciones, que realizan tareas en beneficio directo del usuario final. Este es el significado original del término. Es posible que un ordenador cumpla simultáneamente las funciones de cliente y de servidor.
Una computadora en la que se ejecuta un programa que realiza alguna tarea en beneficio de otras aplicaciones llamadas clientes, tanto si se trata de un ordenador central (mainframe), un miniordenador, una computadora personal, una PDA o un sistema embebido; sin embargo, hay computadoras destinadas únicamente a proveer los servicios de estos programas: estos son los servidores por antonomasia.


Ejemplo de un servidor del tipo rack.
Un servidor no es necesariamente una máquina de última generación de grandes proporciones, no es necesariamente un superordenador; un servidor puede ser desde una computadora vieja, hasta una máquina sumamente potente (ej.: servidores web, bases de datos grandes, etc. Procesadores especiales y hasta varios terabytes de memoria). Todo esto depende del uso que se le dé al servidor. Si usted lo desea, puede convertir al equipo desde el cual usted está leyendo esto en un servidor instalando un programa que trabaje por la red y a la que los usuarios de su red ingresen a través de un programa de servidor web como Apache.
Por lo cual podemos llegar a la conclusión de que un servidor también puede ser un proceso que entrega información o sirve a otro proceso. El modelo Cliente-servidor no necesariamente implica tener dos ordenadores, ya que un proceso cliente puede solicitar algo como una impresión a un proceso servidor en un mismo ordenador.
