Web Server VS Application Server

Web Server

• Web Server is a specialized software or hardware system designed to serve web content over the internet or an intranet.
• It primarily handles HTTP(S) requests and responses, serving static web pages, files, and media to clients, typically web browsers.
• It is responsible for processing client requests, locating and retrieving web resources, and sending them back to the requesting clients.

Examples

• Apache HTTP Server: Apache is one of the most widely used open-source web servers, known for its flexibility and robustness.
• Nginx: Nginx is a lightweight and high-performance web server and reverse proxy server, commonly used for serving static content and load balancing.
• Microsoft Internet Information Services (IIS): IIS is a web server developed by Microsoft for Windows servers, widely used in Windows-based hosting environments.

Application Server

• Application server is a software framework or platform that provides a runtime environment for executing server-side applications.
• It is designed to run dynamic, business logic-driven applications, often using various programming languages and technologies.
• It offers features like connection pooling, transaction management, security, and scalability to support the execution of web applications.

Examples

• Apache Tomcat: Tomcat is an open-source application server developed by the Apache Software Foundation, primarily used for running Java-based web applications (Servlets and JSP).
• WildFly (formerly JBoss): WildFly is an open-source Java EE (Enterprise Edition) application server developed by Red Hat, designed for Java-based enterprise applications.
• Microsoft Azure App Service: Azure App Service is a platform-as-a-service (PaaS) offering by Microsoft for hosting web applications, supporting multiple programming languages and frameworks.

Comparison

Primary Function:

• Web Server: Web servers primarily serve static content and handle HTTP(S) requests and responses.
• Application Server: Application servers execute dynamic applications, process business logic, and manage application components.

Content Generation:

• Web Server: Web servers deliver static content directly to clients, such as HTML, CSS, JavaScript, and media files.
• Application Server: Application servers generate dynamic content by processing client requests, interacting with databases, and executing application logic.

Language Support:

• Web Server: Web servers are often language-agnostic and mainly serve static content.
• Application Server: Application servers are tailored to specific programming languages and frameworks, such as Java EE, ASP.NET, or Ruby on Rails.

Transaction Management:

• Web Server: Web servers typically lack advanced transaction management capabilities.
• Application Server: Application servers offer transaction management to ensure data consistency and integrity within applications.

Scalability and Load Balancing:

• Web Server: Web servers can be easily horizontally scaled to handle increased web traffic and are often used with load balancers.
• Application Server: Application servers also support horizontal scaling but require careful session management and load balancing for stateful applications.

In modern web applications, both types of servers may work together to deliver a complete and scalable solution.
