List of Top 10 Application Server Software

Application Server Software

An application server helps to install, operate, and host different web applications for consumers, IT companies, and large-scale and small-scale organizations. It connects various networks and databases. Looking to know the best application server software then this post will give your brief about the best.

It is often a complicated process to work with different computational elements to run specific tasks that need to work together to power multiple web-based software and applications.

Here is where application server software comes into the picture. Application servers bridge the gap between primary web-based servers and the back-end tier of a server. It also supports the use of various protocols and application programming interfaces (APIs).

Application servers are classified in different ways, such as:

  • Web servers,
  • The database application server, and
  • General-purpose or enterprise application servers.

Since application servers are versatile, 2, or even more, servers can be combined to work as a web application server. Before going to discuss the top 10 application servers, let’s first know why you need an application server?

Why Use an Application Server?

“Why should I have an application server?” Is that on the mind that let me tell you that application servers work the best when you need to integrate them with different servers and databases?

Not having an application server can create different versions of the same application within the organization resulting in a lack of integrity and compatibility issues.

Since the application servers sit between the web pages and the organization’s database, it, also, acts as an additional security layer and protects your site against SQL cyber attacks.

Application servers can also pool database connections and act as a web farm without any additional connections to the underlying database. They allow the developers to focus on the application and spend less time mulling over security.
