Application server computing is a modern form of platform middleware that provides an efficient and organized way of hosting business applications. It sits between the operating system, external resources, and user applications, acting as a host for user’s business logic while facilitating access and performance of the application.
Application servers were designed to accommodate the growing number of applications that were brought to the internet and their increasing complexity. They are network computers that run and store an application for client computers, serving as an intermediary between the database server and the end-user or client program. The primary objective is to reduce the size and complexity of client programs, cache and control data flow for better performance, and provide security for both data and user traffic.
Application server computing must function despite variable and competing traffic of client requests, hardware and software failures, potential heterogeneity of data, and processing resources required to meet the business needs of the applications. It is essential in providing efficient and secure hosting of business applications.
Frequently Asked Questions (FAQ)
What is an application server?
