What is Servers & Server Management

With server virtualization making it possible to run several operating systems and applications on limited hardware resources, the task of server management is becoming even more challenging. According to the Forrester research poll, nearly one-fourth of respondents have virtualized their servers. And around 50 percent of them will adopt server virtualization in the next two years. With this, companies have to manage virtual servers along with physical servers while maintaining the consistency and standardization.

The focus of server management is now on drift prevention and effective management of templates. Virtual server management can also help in determining complexity of virtual servers and finding the root cause of performance issues. As issues of physical servers manifest in virtual machines and vice versa, server management becomes quite important.

A server is a computer program, which is designed to process requests to client computers over the internet or local network. It is also helpful in delivering data over the computer network. Server Read More

Frequently Asked Questions

server is a computer designed to process requests and deliver data to other (client) computers over a local network or the internet. Although any computer running special software can function as a server, the most typical use of the word references the very large, high-powered machines that function as the pumps pushing and pulling data across the internet.

Most computer networks support one or more servers that handle specialized tasks.

The server is the software that handles a task. However, the powerful hardware that supports this software is also usually called a server because server software coordinating a network of hundreds or thousands of clients requires hardware much more robust than what the buy for ordinary consumer use.

A large, general-purpose network supporting a medium-sized company will likely deploy several different types of servers:

  • Web Servers , to show pages and run apps in connecting Web browsers
  • Email servers, to facilitate the sending and receiving of messages
  • FTP servers, to support the moving of files through File Transfer Protocols tools
  • Identity servers, to support logins and security roles for authorized users

Hundreds of different types of specialized server types support computer networks. Apart from the common corporate types, home users often interface with online game servers, chat servers and even streaming-audio services.

The word Cluster is used broadly in computer networking to refer to implementations of shared computing resources. Typically, a cluster integrates the resources of two or more computing devices that could otherwise function separately (often, workstation or server devices) together for some common purpose.

A Server Cluster is a collection of servers , called nodes that communicate with each other to make a set of services highly available to clients.

A Web server farm (a collection of networked Web servers, each with access to content on the same site) function as a cluster conceptually. However, purists debate the technical classification of a server farm as a cluster, depending on the details of the hardware and software configuration.

A server is a computer program that provides services to other computer programs (and their users) in the same or other computers. The computer on which a server program runs in is also frequently referred to as a server. The Computer machine may be a dedicated server or used for other purposes as well. Popular Servers are Apache, Nginx, Lighttpd, litespeed (not free), Open litespeed (free version), IIS (Microsoft, not opensource), HHVM.

Server is basically a machine that holds data with the cloud data catching up simply processes data from multiple client machines. Usually an efficient sever would have more processing power than the client interfaces provide. The possibilities are endless with the server. Use it as a database, inquiry form, an intelligent machine (deep learning with gpus), it can simply be a relay point to connect two clients like a voip telephone exchange form server. It can be a banking system that maintains what you put in or withdraw from your account.

There are several noteworthy differences between Standard, General Purpose, and work-optimized cloud servers:-

  • General Purpose servers use faster solid state drives (SSD) compared to the standard spinning disk allocation for Standard servers.

 

  • Only work-optimized servers (I/O, Compute, or Memory flavors) can boot from Cloud Block Storage.

 

  • For both General Purpose and Standard servers, you can choose the size of your system disk (50 GB-1 TB), but the system disk is fixed for work-optimized servers.

 

  • Up to 240 GB of RAM is available on work-optimized servers (Memory flavor), whereas Standard servers provide up to 30 GB of RAM.

 

  • You can have up to 32 vCPUs running on work-optimized servers, compared to the maximum of 8 on the Standard Cloud Servers.

Traditionally, Servers are of four types:-

  1. FTP servers
  2. Proxy servers,
  3. Online game servers
  4. Web servers
  • FTP Server

File Transfer Protocol (FTP )  is one of the oldest server types. It is responsible for transferring files from server to a computer and vice versa.  FTP server ensures the security and integrity of data during the transfer. It is commonly used by web servers, it enables user to upload, edit or delete files from websites using FTP clients.

  • Proxy Servers

The Proxy server is responsible for a connection between a client(web browser or an app) with and an external server to entertain the request for connection, performance enhancement, and accessibility

  • Online Gaming Server

Gaming server has gained its popularity in a recent decay. This type of server is responsible for connecting hundreds of gamers around the world to an external server(s) for accessing gaming data.

  • Web servers

The web server is responsible for hosting website files and serve it up through a web browser. It loads an individual file of a web page and loads it to display in the browser as one complete page. HTTP or HTTPS (Hypertext Transfer Protocol or Hypertext Transfer Protocol Secure) communicate between server and web browser to load a web page.
