While request–response is the most common client-server design, there are others, such as the publish–subscribe pattern. This is because the server software that coordinates a network of hundreds or thousands of clients requires hardware that's more robust than computers for consumer use. For most WebRTC applications to function a server is required for relaying the traffic between peers, since a direct socket is often not possible between the clients (unless they reside on the same local network). For the average home user looking for a basic, infrequently used server, one built from a desktop computer could work but most businesses will find that a ready-made, dedicated server is a better choice. To support high-end needs, an application server has to have built-in redundancy, monitors for high-availability, high-performance distributed application services and support for complex database access. Server virtualization is the process of creating multiple server instances from one physical server. In computing, "server" dates at least to RFC 5 (1969),[4] one of the earliest documents describing ARPANET (the predecessor of Internet), and is contrasted with "user", distinguishing two types of host: "server-host" and "user-host". This is in contrast with peer-to-peer model in which the relationship is on-demand reciprocation. These servers are also sometimes virtual machines, meaning that one storage device can host multiple servers, which saves physical space and money. Looking for a used server for sale? [a] The word service (noun) may refer to either the abstract form of functionality, e.g. A Web server is a program that uses HTTP (Hypertext Transfer Protocol) to serve the files that form Web pages to users, in response to their requests, which are forwarded by their computers' HTTP clients. VMWare Virtual Machines Allows You to Maximixe Server Resources.

Introduction to LANs, WANs, and Other Kinds of Area Networks. Server casings are usually flat and wide, and designed to be rack-mounted, either on 19-inch racks or on Open Racks. This architecture is called the client–server model. While some dedicated servers focus on one function, such as a print server or database server, some implementations use one server for multiple purposes. The use of "serving" also dates to early documents, such as RFC 4,[5] contrasting "serving-host" with "using-host". On the Internet the dominant operating systems among servers are UNIX-like open-source distributions, such as those based on Linux and FreeBSD,[15] with Windows Server also having a significant share. On the hardware side, a web server is a computer that stores web server software and a website's component files. Most home operating systems are also void of server-related features.

These types of servers are often housed in dedicated data centers. A server farm or server cluster is a collection of computer servers maintained by an organization to supply server functionality far beyond the capability of a single device. A single server can serve multiple clients, and a single client can use multiple servers. For example, if files on a device are shared by some process, that process is a file server. A class of small specialist servers called network appliances are generally at the low end of the scale, often being smaller than common desktop computers. Web service. Since uptime is critically important for most servers, servers aren't designed to shut down but instead run 24/7. Proprietary operating systems such as z/OS and macOS Server are also deployed, but in much smaller numbers. When a web server takes down information permanently, or even temporarily, you might still be able to access those files if a third-party service archived it. However, purists debate the technical classification of a server farm as a cluster, depending on the details of the hardware and software configuration. Some orders may experience slight delays. A server is a computer designed to process requests and deliver data to another computer over the internet or a local network. A web server farm is a collection of networked web servers, each with access to content on the same site. Large businesses that have multiple servers don't typically access these servers locally, like with a keyboard and mouse, but instead by remote access.

Some high-profile companies using Apache include Cisco, IBM, Salesforce, General Electric, Adobe, VMware, Xerox, LinkedIn, Facebook, Hewlett-Packard, AT&T, Siemens, eBay, and many more (). A server operating system (OS) is a type of operating system that is designed to be installed and used on a server computer. Client–server systems are today most frequently implemented by (and often identified with) the request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledgment. One of the most basic web hosting terms is “web server.” Web servers are the focal point of web hosting. However, servers sometimes go down intentionally for scheduled maintenance, which is why some websites and services notify users of scheduled downtime or scheduled maintenance. Cloud Server is a high availability and redundant multi-tenant Cloud solution. Although any computer running the necessary software can function as a server, the most typical use of the word references the enormous, high-powered machines that push and pull data from the internet. The role of a server is to share data as well as to share resources and distribute work. These will normally have very stable power and Internet and increased security. Cloud Servers are built for customers that want to move to the cloud for easy deployment, scalability, and reduced spend. Environmental groups have placed focus on the carbon emissions of data centers as it accounts to 200 million metric tons of carbon dioxide in a year. A server is a computer program or device that provides a service to another computer program and its user, also known as the client. Typically, a cluster integrates the resources of two or more computing devices that could otherwise function separately for some common purpose (often a workstation or server device). The client must be a networked computer; otherwise, there would be no client-server model. Advanced detection and alerting on conditions such as overheating, processor and disk failure. The use of the word server in computing comes from queueing theory,[3] where it dates to the mid 20th century, being notably used in Kendall (1953) (along with "service"), the paper that introduced Kendall's notation. In computing, a server is a piece of computer hardware or software (computer program) that provides functionality for other programs or devices, called "clients". An alternative model, called peer-to-peer networking, allows all the devices on a network to function as either a server or client on an as-needed basis. In addition to server, the words serve and service (as noun and as verb) are frequently used, though servicer and servant are not. Mission-critical enterprise servers would be very fault tolerant and use specialized hardware with low failure rates in order to maximize uptime. The information stored on the server is stored in the relational database. A single server can serve multiple clients, and a single client can use multiple servers. This makes it suitable for use in the VPS web hosting plans. Servers are more often than not, more powerful and expensive than the clients that connect to them. The Jargon File defines "server" in the common sense of a process performing service for requests, usually remote, with the 1981 (1.1.0) version reading: SERVER n.
