What Is an Application Server and How It Works?
An application server usually sits in between the database and network. However, it is playing a major role in the functioning of an application. If you are developing applications, you should have a clear understanding of what is an application server. Continue to read and we will share all the information that you need to know about application servers.
What Is an Application Server?
In simple terms, you can call it a mixed framework of software, which is providing you with the chance to create web applications and run them in a server environment. The application servers can usually be complex as you can discover numerous computational elements running in them. These computational elements are designed to cater to different tasks that you have. No matter what, they are in a position to power up web-based software, multiple clouds, and applications.
The application server is usually sitting in between the back-end tier you can find in a database server and a web-based tier you can find in an application server. You are provided with numerous APIs to access the functionality offered.

People usually tend to pair web servers with application servers. Or else, it is possible for you to discover web servers within application servers. When this feature is available, you will be able to converge them to get a web application server. This is where you can run web applications within the server and make them available for people to access. The application servers can come along with their user interfaces so that people can manage.

How Application Server Works?
Upon discovering answers to the question on what is an application server, you should figure out how an application server would work.

Both business users, as well as residential service subscribers, will be able to get them. You just need to understand how application server works and then continue to get the desired functionality based on your preferences.
Back in the day, application servers were being used for IP Centrex applications and VoIP applications. However, you can now see how application servers are being used for many other applications, such as IP communications such as unified text chat, video, voice, and presence.
What Is an Application Server Used For?
Along with understanding what an application server is, you should also understand the uses of an application server. When you have a need to integrate a web application along with a database and server, you can think about using an application server.
One of the key benefits that come along with application servers is the ability to provide integrity to data and code. That’s because you can have a centralized approach to keep the applications updated and upgraded in a convenient manner. In case if you don’t have an application server, you will end up getting different versions of the same app throughout numerous platforms. This will eventually lead you to issues with software compatibility.
When it comes to the question “what is the purpose of an application server?“, you can also think about using it to get an extra layer of security. That’s because the application server would sit in between databases and web pages. Based on that, the application server would act in the form of an additional barrier to ensure your protection against the cyber-attacks that take place in the form of SQL injection. You can experience this benefit as there is no interconnection between a database and a web page. You can keep peace of mind as you are receiving maximum protection against malicious SQL injections.
If you are having a large and heavily used application, you will come across the need to enhance its performance. This is where you should look for what is an application server. Then you will be able to have extra control over the traffic that your application is receiving. This will contribute a lot towards the performance of large applications. Along with that, you will also be able to minimize the overheads that you will have to face when managing them.
An application server can easily be managed. When you look at what are application server examples, you will notice how many application servers are put in place because of this benefit. You will be able to pool the database connections based on your preferences. This is why you can easily scale out the application server based on your needs. On the other hand, it has the potential to act in the form of a web server farm as well. There is no need for you to worry too much about introducing any additional connections into the underlying databases for experiencing this benefit.
Types of Application Servers
Some of the most popular application server examples are listed below:
- Glassfish: It is provided by Sun Microsystem and now is acquired by Oracle
- Websphere: It is provided by IBM
- JBoss: It is an open-source server that is provided by the JBoss community
- Weblogic: It is provided by Oracle and it is more secure than the previous ones mentioned above
In this article, you could get to know about what is an application server and what does an application server does. While keeping this in mind, you can continue to use an application server and get the desired functionality offered out of it. You will be able to receive numerous applications out of an application server. On top of that, you will often be able to group together the functions of an application server, so that you can deliver much-needed support to all the sub-systems. Along with that, you can provide them with the chance to create a comprehensive service platform. For more detailed information, check this post out!
