Difference Between Application Server and Web Server
The IT industry uses many specialist terms and often, some of them can be confusing, causing many to mix them up wrongly. Consider the difference between web server and application server. Are these two commonly used technical terms the same or are there important differences between them? To answer the question of what is the difference between application server and web server, we must first look at their functions.
A web server serves displays information on the internet and responds to simple requests. An application server is designed to work with different types of content, allowing it to not only display information, but also to interact with users and to process complex computing requests.
Some in the industry use the two words interchangeably; ideally this should not be the case. There is a real and practical difference between application server and web server, which we shall examine in the article below.
Definition of Application Server
An application server is a software that handles HTTP content, but it is not only limited to this type of content. This capability allows it to perform complex computing tasks, as well as display information. These types of servers are dynamic and can process several requests at the same time.
To fully understand the definition of application server, we must look at its functions in depth. This type of server has within it special inbuilt features to enable it perform these functions, and can interact with programming languages like Java and PHP.
Definition of Web Server
Given the crucial role that websites play in the digital age, web servers are a vital in keeping the flow of information seamless. A web server is a software that handles only HTTP protocols. This capability allows it to display information and quickly respond to simple requests from users.
The definition of web server, encompasses how they function. They display content by integrating with search engines, and thus making it easier for the end user to get the information they need in an instant.
Application Server vs Web Server Comparison Table
|Basis of Comparison||Application Server||Web Server|
|Software used to host websites. They carry out complex computing and business-related tasks. These include incorporating databases, transactions, and graphical user interfaces or GUI’s||Software used to only host websites. They display information and respond to simple user queries|
|Content||Serves HTTP content, but is not only limited to this||Serves HTTP content only|
|IT Capabilities||Accepts and responds to dynamic content||Accepts and responds to static content only|
|Business Applications||Applied to business-related applications such as mobile apps, which require complex interactions with the end user||Serve web-based applications only. They do so by carrying out simple tasks such as displaying information and responding to simple requests|
|Examples||Oracle WebLogic, Apache TomEE, Wildfly, IBM WebSphere||Apache, Microsoft IIS, Jetty, Roxen, LiteSpeed|
Conclusion of the Main Difference Between Application Server vs Web Server
Having looked at the difference between web servers vs. application servers, several key conclusions come to mind.
Firstly, an application server is flexible and accommodates several requests at the same time giving it the capability to perform complex, logical computing tasks, while a web server only displays information and responds to simple requests.
Radically modifying the functions of a web server can lead to errors and what is commonly known as a ‘website crash.’ However, with application servers, content is dynamic. Information seamlessly travels back and forth between the end user and the server; this cannot happen with web servers.
App servers work in tandem with web servers, and indeed, in the world of e-commerce, many web servers integrate with app servers to make online transactions possible. Both help a website to function properly, and by combining the two, we create the basis for the success of many online stores.
Because of this integration, two different consumers can both look at the same information in real time – goods they may wish to purchase online, for instance – present search queries with different criteria simultaneously, and receive their two different answers, also in real time. This is what makes for a seamless, convenient, and quick online shopping experience on many an e-commerce store.
