Application Servers & Web Application Servers | Definitions, Functions and Examples

An application server is a bridge that connects the user interface and back-end processes. It is like a rope of communication used to maintain and execute core functions to run web applications.

Read as 98thPercentile reveals the hidden interaction between the front and back ends and explains application server functions and examples of web application servers.

Definition of Application Server:

An app server is a software framework that offers a platform for running and managing applications. It functions as an intermediary between the database back-end and the user, where it manages the logic, calculations, and actions necessary for the application. This infrastructure is important to enable lively and interactive user experiences across different platforms to ensure smooth, secure, and efficient program execution.

Functions:

1. Application Execution: The main responsibility of an application server is executing business logic as well as operations needed by applications. Application servers offer a runtime environment plus tools necessary to deploy and run complex applications.

2. Connection Management: Clients, servers, and databases are connected by application servers. Communication protocols are handled by them and ensure seamless data transfer between various components in an application.

3. Transaction Management: Every operation within a transaction must be completed before it can be committed; this is one of their most important roles.

4. Security: They guard access by users, preserve sensitive data, or even limit interaction with authorized users only.

5. Scalability: Application servers do allow addition of resources to handle the increasing loads.

6. Load Balancing: Application servers end up splitting incoming requests across several servers in order that no one server is overwhelmed.

7. Resource Management: These applications servers allocate resources dynamically depending on the current load and needs of the application thus ensuring the best use of hardware and software assets.

8. Integration: With that said, application servers ease communication as well as data interchange between different applications and services through offering APIs, messaging systems and other tools for making it possible for different software components to work together smoothly.

Understanding what is Web Application Server?

A web application server is specifically meant for handling web-based applications. It does serve dynamic content, process web requests, and connects with databases among other back-end systems.

Examples

1.      Apache Tomcat

·       Type: Web Application Server

·       Features: Servlet container, JSP engine, HTTP server.

·       Use Cases: Java-based web applications, RESTful services.

 

2.      JBoss (WildFly)

·       Type: Application Server

·       Features: Full Java EE support, clustering, high availability.

·       Use Cases: Enterprise applications, microservices.

 

3.      Microsoft IIS (Internet Information Services)

·       Type: Web Application Server

·       Features: ASP.NET support, HTTP/2, security features.

·       Use Cases: ASP.NET applications, web hosting.

 

4.      IBM WebSphere

·       Type: Application Server

·       Features: Java EE support, enterprise-level scalability, integration tools.

·       Use Cases: Large-scale enterprise applications.

 

5.      Oracle WebLogic

·       Type: Application Server

·       Features: Java EE support, clustering, high performance.

·       Use Cases: Enterprise applications, cloud-native applications.

Application servers have become increasingly important in the modern IT environment due to their role in providing reliable and efficient infrastructures upon which complex applications can be run. They offer many services such as security, scalability, load balancing, or transaction management, making them a must-have tool in every enterprise or company dealing with programming.

Application servers offer dynamic content instead of static content. Would you like to know more about HTML, CSS, static content, and other computer languages? Then, surf the premier resource and online programming course provider, 98thPercentile, and begin your coding career right away.

Mastering Arithmetic with Multiplication Charts: A Comprehensive Guide

Mathematics is a fundamental part of education, and mastering the basics is crucial for further advancement in the subject. One of the essential tools for learning multiplication is the multiplication chart. This article delves into the importance of multiplication charts, particularly focusing on the Multiplication Charts 1 - 12, and how they serve as a cornerstone for arithmetic proficiency. Understanding Multiplication Chart A multiplication chart is a grid that helps students learn and visualize the products of multiplying two numbers. These charts are especially helpful in the foundational stages of learning math, as they provide a clear and organized way to see the relationships between numbers. Each cell in the chart represents the product of the row and column headers. For instance, in a typical Multiplication Chart 1 - 12, the intersection of the row labeled '3' and the column labeled '4' would show the product '12'. This visual representation makes it...
