Web Server

A web server runs websites. As per the user’s request, they distribute the web pages based on computer programming. They manage network resources. Every web server first stores, sets up, processes, and delivers web pages to server users, which is the primary goal of the web server.

Every Web server has a possible domain name, an IP address. Hypertext Transfer Protocol (HTTP) used for the intercommunication system. HTTP server understands the web addresses (URLs) and HTTP protocol browser uses to view web pages. It can be accessed through the domains of websites it stores and delivers content material to the end-user device. Web servers can be set up to send/receive an email, manage print jobs, control access to a network, or host a website

Web Application Server

The application server executes server codes and gathers dynamic content. E.g., EJB, Servlet, or JSP. It hosts applications. It is not just a browser, but it can serve a request. A web application comprises an application code written to play out some action(s) on a web server and show the outcome to an internet browser customer. It usually refers to Java application servers.

It is intended to install, operate, and host applications related services for end clients. Application server structures are programming systems for building application servers. An application server structure gives the two facilities to a server environment to run and make web applications.


1. Key Features

Web Server

  • Data storage

Create multiple websites and store every web server with a sample storage space that supports the large file.

  • FTP

It creates an FTP site that allows end-users to share files to and from the website. It Creates virtual directories and then maps them to physical lists.

  • Configuration

Configure to a log file settings, which includes what data to include on the log files, where the log files are saved.

  • Privacy and security

Configure website security like which IP addresses and which user accounts are allowed to view the website.

  • To regulate network traffic web server has a Bandwidth controlling system

The web server has access to minimize excess network traffic and regulator the network traffic.

  • Server-side web scripting

This feature lets the user create a dynamic web page by this feature.                                     

  • Building Tools

Even without prior experience or knowledge, these tools are offered as part of a hosting web package. The advanced tools teach how to add an album, guestbook, ads, auto-installer software for blogs, visitor trackers, banner rotators, photo newsletters, blogs, galleries FAQ modules, forums, and much more.


Web Application Servers

  • Data redundancy

It is defined as the storing of the same data in different locations. For example, data redundancy can save the same file ten times to ten different disks.

  • High availability

It is referred to as a durable system and operates continuously systems that are without failure. It is a group of servers and supports server applications. For failover servers and backup networks, like load balancing, users require high availability clusters.

  • Load balancing

It distributes network traffic across multiple servers to ensure no single server has too much demand. It spreads the work evenly and improves application responsiveness and also increases the availability of websites and applications for users.

  • Security

It has Single sign-on across all Web Server applications inside a single security domain. And it has a Programmatic login.

  • User Management

The user management engine provides the user management functions for Java-based applications on SAP NetWeaver Application Server Java. For user administration on AS Java, it Used identity management.




Web Server

Web server reacts to the customer demand in both following ways:

  • Generating response by summoning a script and communicating with the database
  • Sending the file to the customer associated with the requested URL.
  • When the customer sends demand for a website page, the web server looks for the mentioned page when the page is discovered, then it will send it to the customer with an HTTP response.
  • If the mentioned page isn’t discovered, the webserver will send an Error 404 Not found HTTP response message.
  • If the customer has mentioned some different resources, the web server will contact the application server and store information to develop the HTTP reaction.

Web Application Servers

An application server is a Java Virtual Machine that runs user applications. It collaborates with the webserver to give a customized dynamic response to a user request. The user request can consist of JSP files, servlets, and enterprise beans, and their supporting classes.If a web browser visits a company website

  • The user sends requests to access the data from a database.
  • The web server follows the user request.
  •  It passes the request to one of its application servers on which the application is running and then processes the client request.
  • The application server and the webserver collaborates to return the results to the client on the web browser.



Web Servers

  • Mail Server

This application is used for the sending and receiving the email over the internet. It gets the mail from the user and forwards it to next.

  • Proxy Server

This software works as an intermediate between two endpoints and runs on a computer. A client or user is requesting a service to the server via this proxy server.

  • Telnet Server

Telnet server serves a host computer to clients on whom they log on and performs their task like remote computer

  • Web Server

In the web server, all transfer is mediated by the browser—even servers using HTTP to communicate.

  • Virtual Server

Virtual server is software and a program that runs as a shared program, but clients feel that they have complete control of a server.

  • Real-Time Communication Server

Real-Time Communication Server is also known as a chat server. The client uses his server as a messaging server. A large number of users can exchange their information by using this server.

 Web Application Servers

  • Active Application Server

it provides a productive environment and support to business logic, which is involved in the server-side and expressed in the form of components, objects, and Rules. These kinds of servers are also referred to as a stateful server.

  • Web Information Server

It generates pages from the database by using HTML templates. These kinds of servers are also referred to as stateless servers.

  • Component Server

To provide the database access to software components like DLL, Java Bean, and COBRA, it plays a primary role and provides support to the transaction processing requests.


4. Examples

Web Servers

  • Nix Web Server. free, open-source and high-performance HTTP server
  • Apache Web Server: Most popular server.
  • Litespeed Web Server can handle much more traffic.

Web Application Servers

  • Jobs: Open-source and used for implementing Java applications and a variety of other software applications.
  • Glassfish: can also be used as a Web Server and can handle servlets & JSP.
  • Web logic: It is more secured and Provided by Oracle




The main difference between the application server and the Web server is that Application servers give dynamic content while Web servers provide static content. Application servers utilize very high resources, while web servers use low resources. Web application servers support Multithreading while web servers do not support Multithreading. Application servers contain web and EJB containers and a web server, while web servers cannot be used for EJB; it only involves web and EJB containers.
