App servers facilitates the hosting and delivery of high‑end web applications, so users experience the app as it was intended.
What Is an App Server?
An application server’s fundamental job is to provide its clients with access to what is commonly called business logic, which generates dynamic content; that is, it’s code that transforms data to provide the specialized functionality offered by a business, service, or application. An application server’s clients are often applications themselves, and can include web servers and other application servers. Communication between the application server and its clients might take the form of HTTP messages, but that is not required as it is for communication between web servers and their clients. Many other protocols are popular, including the variants of CGI.
What is the Difference Between a Web Server and an App Server?
Web servers simply deliver static content for a website, including the HTML pages, image files, video files, and other types of files included in the website. App servers, on the other hand, generate dynamic content and deliver that to the user’s web browser. App servers can never substitute for web servers. Instead, web servers and application servers must work together to deliver a seamless browsing experience to web user.
