hat is a server? So many people in the I.T. industry and small businesses use the term and sometimes aren’t even sure, what is a server? The term server is used quite broadly in information technology. Despite the many server-branded products available (such as server versions of hardware, software or operating systems), in theory any computerized process that shares a resource to one or more client processes is a server. To illustrate this, take the common example of file sharing. While the existence of files on a machine does not classify it as a server, the mechanism which shares these files to clients by the operating system is the server.
In the hardware sense, the word server typically designates computer models intended for hosting software applications under the heavy demand of a network environment. In this client–server configuration one or more machines, either a computer or a computer appliance, share information with each other with one acting as a host for the other[s].
While nearly any personal computer is capable of acting as a network server, a dedicated server will contain features making it more suitable for production environments. These features may include a faster CPU, increased high-performance RAM, and increased storage capacity in the form of a larger or multiple hard drives. Servers also typically have reliability, availability and serviceability (RAS) and fault tolerance features, such as redundancy in power supplies, storage (as in RAID), and network connections.
The introduction of Cloud computing allows server storage and other resources to be shared in a pool and provides servers with a higher degree of fault tolerance.
Selecting a Server OS: What is Server OS? What is Windows Server 2008? Small Business Server?
What is server OS? So you’re looking at moving to a client-server model. You want to take the documents that are randomly scattered on the hard disks of the office PCs and manage them in a single directory, accessible at any time from any PC in the office. Maybe you want to get your own Internet domain name and have a Web site that you host locally, or build an Intranet for staff information and communication. Perhaps you just want to take your single DSL link and provide secure Net access for everybody in the office. Where to you go from here? Windows Server 2008 has been well proven in the market and it is a trustworthy and stable operating system.
If you’re running a small business and have more than two or three PCs in the office, it’s time to start looking at setting up a server. One of your first considerations will be which server operating system (OS) to use.
Server Operating Systems are designed from the ground up to provide platforms for multi-user, frequently business-critical, networked applications. As such, the focus of such operating systems tends to be security, stability and collaboration, rather than user interface.
Server Operating Systems provide a platform for multi-user applications, and most come bundled with a batch of common server applications, such as Web servers, e-mail agents and terminal services.
