What is an Application Service Provider Explained in detail.

Over the Internet, an Application Service Provider (ASP) provides apps and related services. For a charge, businesses can rent ASP software. The software is accessible remotely via a web browser rather than being installed locally on a company’s hard discs. Software-as-a-Service refers to a multi-tenant variation of this model (SaaS).

ASP services have in the market as a viable alternative to purchasing software, particularly for small and medium-sized organizations with limited IT resources. ASP services are being used by larger enterprises as a type of outsourcing. Reduction in  IT capital expenditures, quicker software and hardware maintenance (such as automatic software upgrades), and improved engagement with mobile users are all advantages of using an application service provider. The application service provider approach (also known as the asp model) is also useful for specialized programs that would be prohibitively expensive to install and maintain on business PCs.

By providing automatic upgrades and technical assistance, ASP services make software less expensive and easier to use for businesses. The concept of centralized processing or computing was introduced by application service providers, which allows users to access a single central copy of software rather than acquiring and maintaining several versions on each individual computer.

What are ASPs and how do they work?

ASPs used the internet or a private network to deliver applications. Clients could be charged in one of four ways: a usage-based fee structure, a fee based on features, a flat monthly or annual fee, or a mix of the three.

Hosting, maintenance, and support were all included in the fees. In this paradigm, ASPs created a unique environment for each client, which was not shared with other clients. This single-tenancy method ensured operational security and continuity.

In the late 1990s and early 2000s, the ASP definition was a little hazy. Many of the first application service providers (ASPs) exclusively supplied their own applications. Other application service providers (ASPs) hosted and bundled a variety of third-party programs, many of which were simple collaboration tools. However, surviving ASPs were forced to offer more integrated applications and rebrand or reimagine themselves as managed service providers (MSPs), web service providers, or application infrastructure providers after the ASP sector nearly collapsed in the early 2000s.

The industry eventually gave way to the software as a service (SaaS) and platform as a service (PaaS) models. Both the SaaS and PaaS models usually combine proprietary and third-party services.

Take a look at the three types of cloud services: SaaS, PaaS, and IaaS.

The benefits and drawbacks of the ASP model-

The ASP technique has a number of benefits and drawbacks, including the following:

ASP advantages-

  • Costs are a benefit of ASP: Because the ASP would handle much of the labor, the customer would theoretically not need to recruit a significant IT workforce. Customers might also shift costs from capital to operational expenses, which some customers found appealing for accounting reasons.
  • Deployment: Because the application’s back end is already up and running, a faster deployment is conceivable.
  • Upgrades: ASPs might track and push software upgrades as part of their service contract, relieving clients of that responsibility.
  • Agreements on service levels (SLAs): These contracts are made to fit the needs of certain clients.

ASP’s drawbacks-

  • Costs: In a single-tenant environment, a customer’s purchased or leased applications are separated from those of other customers. As a result, no economies of scale exist. As a result, as ASPs take on additional clients, expenses do not decrease.
  • Security: Because the majority of ASP clients were small businesses, virtual servers were supplied instead of dedicated servers. Although the true security threats were debatable, the impression of a security issue harmed the early ASP market.
  • Integration is lacking:  Although early ASPs offered software suites, the lack of integration with clients’ old applications hampered the early ASP business.

A comparison of the ASP and SaaS delivery models-

There are several distinctions between the ASP and SaaS delivery models. The consumer typically purchases software and pays an ASP to host and maintain it in an ASP delivery model. SaaS companies either manage software they built themselves or, in many situations, offer both their own and third-party apps.

SaaS Delivery Models

Traditional ASPs featured a single-tenant architecture, which required end-users to install software clients on their PCs. SaaS providers, on the other hand, use a multi-tenant architecture, which means that an application may be accessed via a web browser and serves various customers and organizations.

ASPs aren’t often utilized these days. Customers who require specific, bespoke apps or off-the-shelf applications to be hosted in a secure data center might use an application service provider.

Application Service Providers Examples-

Application service providers come in a variety of shapes and sizes. Among the services provided are:

  • Specialist: Provides a single application for a specific use case, such as processing credit card payments or timesheet services.
  • Vertical market: It Provides an app that a business in a specialized industry, such as a medical practice, would require.
  • Enterprise: Provides a wide range of solutions and software for a variety of sectors.
  • Local/Regional: Provides small-business services to a specific geographic area.
  • . Volume: A low-cost package from a professional application service provider.

Who Are Application Service Providers and What Do They Do?

What is an application service provider?

HP, SAP, and Qwest are application service providers who have joined forces to deliver SAP’s R/3 applications through “cyber centers” that serve other businesses. Another application service provider is Microsoft, which rents out its SQL Server, Exchange, and Windows NT servers.

While application service providers allow smaller businesses to pay as they go for apps, many major businesses sign long-term contracts in exchange for a set number of users or other metrics like compute hours, bandwidth, or storage capacity.

One model for an application service provider is to utilize advertising to give free software. This business model is used by webmail services such as Yahoo, Gmail, Google Docs, and a variety of free online logo producers.

What Is an Application Service Provider and How Does It Work?

Using a configured web browser with plugins, users of an application service provider can remotely access rented software via the Internet. The ASP server can be located on another continent. Users save their work to a remote server and use the web browser interface to execute everyday software activities.

The following features are included in the application service provider model:

  • Bills on a “per-use” or monthly/annual basis 
  • Provides information to customers via the Internet or a thin client computer
  • Multi-tenant access software is used by several application service providers. 

Software-as-a-Service (SaaS) is the term for this (SaaS). Others use virtualization and provide each customer with a license.

Difference between Web Server and Application Server

Web server and Application server are two terms that are used in the same context but still have their own differences, understanding these differences may help you to use these technologies in your favor. In this post, we will see the main difference between Web Server and Application Server with examples.

What is a Web server ?


Before knowing the differences between Web Server and Application Server, lets know about the definitions and use of both servers.

Difference between Web Server and Application Server

A web page is a collection of raw material ranging from images to text files to database context. End users sitting out on a computer somewhere on the internet a web server is a piece of software that runs on the same computer. When you ask for the web page the web server put all those raw material together into a web page and then sent it back out over the internet to your web browser.

Common examples of web server software are Apache and NGINX. Web servers are all about dealing with the HTTP content or content which can be handled over the HTTP protocol. . In a web server system, it stores, process, es and deploys web pages to customer. A customer is either a web browser or a device app. A web server can serve content like pictures, videos, text, and font size.



1. Microsoft IIS-


It is an Internet Information Service platform for web servers, which gives packages for windows-based servers. It specially used to manage to host content on the web page. It also gives GUI to manage websites and user accounts.

2. Eclipse Jetty


Eclipse Jetty delivers web server and container packages and supports HTTP/2 and other integrations like JMX, OSGi, WbSocket, and many more. This software are open source and available free for enterprise use. Jetty is embeddable and asynchronous with cloud computing platforms like Google AppEngine and SaaS like Yahoo. The latest version of Jetty is Jetty 11.0.x, Servlet 5.0 and Java 11+.

What is Application server ?



Application Server Working
Working Process of Application Server

Application servers are specifically designed to run applications by the combination of both hardware and software.  It provides an environment for programs to run. An application server is a server that allows both the creation of web applications and running a business logic that is needed to build and run dynamic content, transaction results, decision support, or real-time analytics. So basically an application server provides the business logic for clients. The application server has its own dynamic features and can be used to create and run dynamic modules. It is a software platform that deploys applications including mobile apps, web, and browser-based applications.

The successful business logic can be implemented using application servers. This business logic causes dynamic changes in data and enables the productivity of applications like transactional activity, decision support app, and real-time scenario analysis. Client-Server communication is the foundation of the Application Server and it includes transaction process, secure network, and concurrency control.

Difference between Web server and Application server ?



Let’s understand the difference between the web server and application server by examples, suppose I have a file ‘script.js’ this file contains a javascript programme, which can be executed and a result can be generated. Now suppose I served this file to my client through a web server, the client will receive only the contents of the file, the javascript won’t be executed.  

But in case of a application server, client  want to serve the ‘script.js ‘ file and wish to execute that file using programming environment.  A Web Server will send the HTML as output for all requests sent to the server.  It does not have any backend logic. So that is the fundamental difference between the a web server and an application server. 

While an application server can do the task which a web server can do too, but webserver can’t do the tasks of an application server.  Yes, there are some plug-ins for a web server that can help a web server to act as an application server to some extent but the efficiency and functionality of an application server can’t be achieved by a web server.

Examples of Application Server:


These examples will help you to understand the difference between Web server and Application server

1. Nginx



It is a web server with open source technology, with load balancing and proxy for mail capacity. As per the study of Netcraft, Nginx can provide service and manages the load of 38% of global websites and 25% engaged sites till December 2019. Nginx used by multiple well-known companies like Netflix, Zynga, and Dropbox.

2. Glassfish



It is a famous open-source application server served on the JAVA platform and developed by Sun Microsystems. The extension of it is now managed by Eclipse Foundation. Glassfish platform reinforces JavaBeans,  Servlets, and many more.

3. WebLogic


It is Oracle’s product of application server to deploy apps in distributed manner using JAVA EE technology. It is fully meshed with Oracle’s platform and cloud services.

3. Apache Tomcat Server



Apache Server is a globally used open-source technology of web-based server runs on Java Servlets. It is used to render and deploy web pages with JAVA code and Java EE (Java Enterprise Edition). Its high-availability Java application server for servlets, JSPs, and WebSockets.

Difference between Web Server and Application Server



Application Server Web Server
Able to deploy dynamic data. Able to deploy static data.
Multiple protocols used like HTTP to develop business logic. Only HTTP protocol is used for communication.
Able to serve websites and business applications Only support website based applications.
Multithreading technology is used to serve multiple clients requests. Do not serve multithreading.
Smoothly running complex processes with resource management. Good for less resource management in web traffic.
Application Database is use to perform connection with backend. Static database is use to connect with backend.
