Despite the size and industry of your business, an application is a critical element in your operations, and server software that can manage the variety of app forms is a good idea.

The idea of app servers emerged from our need for an efficient tool to run hundreds of applications with minimal downtime and more effectiveness.However, the hot debate over the necessity of such technology remains. In this article, we will walk you step by step to understand the basic idea of Application Server Software Solutions, the role of an application server, and when we need one.

What is Application Server Software

An application server is used to deploy, run, and host apps and associated resources for end-users, IT agencies, and enterprises. It enables and facilitates the hosting and deployment of elevated corporate apps by various and connected regional or distant users.

The function of the application server is to act as a host (or container) for the user’s business logic while facilitating access to and performance of the business application.


Resorting to an App server necessitates effective performance amidst the following:

  • Inconsistent and conflicting traffic of user requests
  • Hardware & software malfunctions
  • The decentralized essence of complex apps
  • Potential heterogeneity of data and bandwidth necessary to deliver the business needs.

Thereby, the deployment of application server software must assure optimal performance against the challenges mentioned earlier.

An app server is mainly composed of an operating system (OS) and hardware resources that operate together to perform computing-intensive processes and deliver services to your native apps.

In other words, an application server is important for backup, reliability, network and user management, protection, and a centralized administration interface.

Furthermore, an application server may be linked to business systems, networks, or intranets and accessible remotely through the Internet. App servers can be classified in various ways according to the installed program. For instance, an application server software can be a Web server, database app server, general-purpose app server, or enterprise app server (EA).

Currently, customized app servers are often integrated into operating systems (OS), suite programs such as portals and e-commerce platforms, or other services and are not available as stand-alone products. 

However, as the server software market grows, high performance becomes essential. So when suppliers include upgrades to application servers, including intense workflow and event-based processing capacity, they are now included in this market category.

When do we need an application server?

The primary goal of an application server software is to avoid installing an appl on your desktop. The immediate problem with web servers is that anyone who intends to use a program must install it.

So, to run an Oracle app, for example, you must also have the Oracle client installed. So, now you must install your application and ensure that the Oracle client is present. However, Other apps besides yours are likely to be required to operate on that PC. For example, they might require Oracle8.0 client support, whereas you could require Oracle8i client support.

In reality, you may require version, while another program may require version 8.1.5. As a result, that customer may wind up having two, three, four, or more Oracle software installations, each with its own set of configuration files, and so on. Add to it the fact that each system in this PC environment is a “one-of-a-kind” machine. Each will encounter a distinct problem, a DLL incompatibility, or anything else.

Consider doing the same thing on 1,000 or more devices. It’s not a pleasant experience. Mainly when a bug in your produced program is discovered, you must now locate and notify the 1,000 individuals who have installed your program. They must get and upgrade the patch.

Therefore, an app server software facilitates the complexity of deploying applications of more than one device. Users will have full access with fewer implications. Even when you detect a bug, you fix it, and that’s all there is to it. There are no DLL conflicts, installation problems, or anything else.

Are you frustrated with installing and customizing? App Server offers the solution. First, you go to the website, and there they are, so if you acquire a new PC, there is no need to reinstall your apps.

How Do Application Servers Work?

We will put it as simple as possible; an app server processes the following way:

  • The customer launches a browser and searches for a website.
  • The web server receives the HTTP request, which then delivers the requested web page.
  • Although the web server supports static data requests, the client prefers to utilize an interactive tool.
  • The web server forwards the request to an application server since it is a dynamic data request.
  • The HTTP request is received by the application server and converted into a servlet session by the application server.
  • The servlet connects with the database server, and the app server gets a servlet response.
  • The app server converts the servlet response into HTTP format for client access.

When an app server receives a servlet request from a web server, it evaluates and responds to the web server through a servlet response. Since appl servers typically carry out business logic demands, the webserver interprets the servlet response and returns an HTTP response that the user may view.

App Server vs. Web Server: What’s the Difference?

User content requests are handled by both web and application servers. However, there are numerous significant amounts of different server types, and understanding these variations will assist you in configuring the correct software and hardware architecture for your purposes.

A web server is a computer system that stores, processes, and transmits web pages to clients. Almost usually, the client is a web browser or a mobile application. A web server can host one or many websites, depending on the configuration.

This sort of server fits static HTML content, such as Documents, Images, Videos, and Fonts.

Web servers have traditionally bypassed dynamic content and server-side programming. Instead, web servers accept and fulfill only Hypertext Transfer Protocol (HTTP/HTTPS) queries. However, you can add components to deal with dynamic content as an option.

On the other hand, A software framework that distributes data and resources for a user’s apps is known as an application server. Web-based programs, browsers, and mobile apps are examples of users.

Clients gain access to business logic through application servers. An app server turns data into dynamic content using business logic and allows functionality. Dynamic content examples include:

  • The consequence of a deal
  • Help in making decisions
  • Analytics that is updated in real-time

This server type serves as the primary interface between user and server code.

The Interaction between Web and Application Servers

When web browsers replaced desktop clients as the primary application clients, the distinction between app and web servers grew hazier.

Most web servers offer scripting language plugins (ASP, JSP, PHP, Perl, and so on) that allow for dynamic content production. For instance, adding a.NET plugin to an IIS environment may link the webserver to server-side code and send dynamic content to clients.

On the app server’s side, there is also some overlap. For example, many application servers include a web server and utilize HTTP as the primary protocol.

Due to the overlap in use cases and technology, the most popular servers are hybrids of the two categories. A hybrid solution that mixes server capabilities guarantees that the system runs quickly and efficiently.
