Introduction to Server operating systems

 Generally there are two types of operating systems are available. They are
server OS and Client OS. server OS in the sense it is the capable of creating and maintaining more than 10000 users. All servers are computer on-in network that provides services to other computers on the network.
Example: Web server, print server, file server & etc.

   On the other hand, client OS is capable only minimum level (upto 20 users). This is for only Windows operating systems. But in Linux we can use Linux's client OS as a server OS by use of server tools.

   Consider you are running a Linux server (Or Windows server too), you might be follow the below instructions in order to get the best performance.
Example of server OS: REDHAT 7 server 7, Ubuntu server 14.04.1 & Windows 2012

Characteristics of Server OS

  1. The server OS is should be non user friendly. Because making an non user friendly operating system as a server OS can be protect from accessing third parties in to the server system
  2. The server OS may not have any multimedia features, sound cards & fancy  web browsers. Because this are all unnecessary for a server OS.
  3. The best choice of server interface is CLI. Mostly GUI is not recommended. GUI takes more CPU, power & memory utilizations. 
  4. Another one important  thing is GUI is makes security holes. To be secured CLI is the best way of maintaining server operating system
  5. Run necessary services only. Disable/stop unwanted services. For example, you are maintaining a web server then only run web related services like httpd, Apache and so on. But practically still unwanted services is there on the server. To disabling unwanted services are increases the speed of performance of a server
