Application Server vs. Web Server: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on January 26, 2024
An application server hosts and runs specific software applications, offering complex business logic, while a web server primarily delivers web pages to clients' browsers.

Key Differences

An application server provides a platform for running specific applications, often involving business logic and database interactions, while a web server is specialized in serving static content like HTML, CSS, and images to web browsers.
Application servers are used for complex transactions and workflows in business applications, whereas web servers are ideal for hosting websites and delivering content over the internet.
Application servers can handle dynamic content by executing application code and interacting with databases, while web servers are optimized for fast delivery of static content.
An application server operates in a dynamic environment, often part of a multi-tier architecture, supporting various applications, whereas a web server typically functions in a simpler environment, focusing on HTTP requests and responses.
Application servers interact with end-users through a web interface but execute more complex transactions, while web servers directly handle client requests for web resources.

Application Server and Web Server Definitions

Application Server

They provide middleware services for security and state maintenance.
The application server securely manages sessions for each user’s interactions.

Web Server

They can also serve as a part of a larger application server environment.
The web server works alongside the application server to provide a complete web experience.

Application Server

An application server is a framework that provides an environment for running and managing web applications.
Our company’s website is hosted on an application server that manages all our online services.

Web Server

A web server is a server software or hardware that uses HTTP to serve files that form web pages to users.
When you visit a website, the web server delivers its pages to your browser.

Application Server

Application servers support various programming languages and protocols beyond HTTP.
Our application server uses Java and SOAP to handle complex transactions.

Web Server

Web servers handle HTTP requests from clients and provide HTTP responses.
The web server responded to my request with the requested webpage.

Application Server

It handles the business logic of an application and interacts with databases to deliver functionality.
The application server processes user requests, retrieves data, and provides personalized content.

Web Server

It hosts websites and delivers content like HTML, CSS, and images over the internet.
Our web server hosts the static content of our company’s website.

Application Server

An application server often operates in a distributed architecture for scalable application deployment.
We use an application server to balance the load across multiple servers.

Web Server

A web server is optimized for fast content delivery and is less complex than application servers.
Our web server efficiently delivers thousands of web pages daily to users.
