# Best Application Server Software - Page 3

  *By [Tian Lin](https://research.g2.com/insights/author/tian-lin)*

   Application servers provide a framework for building, deploying, and managing web applications. They offer a variety of critical services required for running web applications, such as security, transaction management, load balancing, clustering for enhanced performance, and diagnostic capabilities. By handling these key operational aspects, application servers allow developers to focus primarily on the development and functionality of the application rather than infrastructure-related concerns like security or scalability.

Businesses across industries use application servers to efficiently develop and manage their web applications, whether for internal use or customer-facing services. These products ensure that applications are stable, secure, and capable of scaling as needed. Application servers are essential for running applications that require high availability, reliability, and consistency, making them a crucial component of enterprise-grade IT environments.

Modern application servers can integrate with a wide range of technologies, including relational databases, messaging services, and web frameworks. They can also support both on-premise and cloud-based deployments, providing flexibility for organizations as they build applications tailored to their infrastructure needs.

In many cases, application servers also support microservices architecture, [containerization software](https://www.g2.com/categories/containerization), and [DevOps software](https://www.g2.com/categories/devops), streamlining the development and deployment process.

Besides core functionalities, many application servers offer advanced features such as support for distributed applications, API integration, caching mechanisms, and automated scaling to handle fluctuating loads. These features help ensure optimal performance and adaptability in dynamic and demanding environments.

To qualify for inclusion in the Application Server category, a product must:

- Provide a software framework for building and deploying web applications
- Offer services such as security, transaction management, and performance optimization to support an application within the hosting server environment
- Integrate with databases, web frameworks, and various technologies to facilitate the development and management of web applications
- Enable scalability and performance enhancements, such as clustering, load balancing, and distributed computing support
- Support modern development methodologies, including microservices, containerization, and DevOps practices

For example, it will check for duplicate messages to the same mobile over 24 hours. This is configurable. \> Ideal for Government as the platform supports the Australian email protective marking standards 2018.3.

The complexity of handling applications has become increasingly complex, and app servers help alleviate these concerns. Application servers can be used across different industries and can be installed based on user requirements.

Application servers are used based on user requirements. A user might need an application for scalability or to improve managing all their web applications. An application server acts as a middleware platform or the second layer since it exists between the first layer, which can be the operating system (OS), the client end, a browser, or a web server, and the third layer, the database server itself. If a company faces high-traffic and latency issues, an application server is used to manage complex requests, monitor high-availability application services, etc.

#### What Types of Application Servers Exist?

There are primarily two different types of servers—application servers and web servers. Application servers are different from web servers since web application servers are static and serve HTTP/HTML requests from the website. Web servers do not serve dynamic or server-side content. A user uses it to pull static HTML content, including files, documents, photos, images, javascript, etc., and can only support HTTP/HTTPS/HTML protocols. These web servers are used to pull web pages for clients using an HTTP server to understand HTTP and URLs. In the case of a web server, the client is the browser where a user can type in their requirements. Application servers provide users access to business logic. In the software industry, business logic is defined as the section of the program that includes real-world business rules on managing data. This business logic works with dynamic content, i.e., transforming the data for specific functionality. Application servers and web servers usually work together. Some web application servers also have plugins from scripting languages such as ASP, PHP, Perl, and JSP.

Servlets can also be opted for, which is a part of a web server that can be run as a separate process. It is a Java programming language class that helps to extend server capabilities. Some web servers are open source, such as Apache Tomcat and JBoss. Application servers can help execute web modules such as Java Servlets and serve JavaEE apps. For example, consider shopping on an e-commerce website. Customers put their items in the cart, add payment details, and check out. However, the sequence of transactions needed falls under business logic—add to cart, add shipping details, add payment details, get OTP for securing the transaction, order confirmation message—this sequence is the business logic.

** ** There are three types of application servers:

**Active application servers:** This application server supports business logic in the form of rules or objects.

**Web information servers:** This type of application server focuses on processing web applications.

**Component servers:** This type of application server helps connect different software components.

### What are the Common Features of Application Servers?

The following are some core features within application servers that can help users in several ways:

**Data redundancy:** One of the features of the application server is data redundancy. Data redundancy is a process where data is kept in two or more separate locations. This is done to ensure business continuity in case of any unforeseen events. Application servers support data redundancy to ensure that in case any business application fails, it can be moved onto another working server and improve application runtime. This helps avoid single points of failure.

**High availability:** Systems, especially mission-critical systems and applications, must run 24/7. Imagine a system on the New York Stock Exchange crashes, or a server in NASA fails. Systems must remain available at all times. However, all systems will have some downtime (planned or unplanned). Application servers for this use case must be high availability (less downtime) to ensure there is no disruption, especially during high peak traffic hours, and able to manage the load, ensuring high performance of the application server.

**Load balancing:** Load balancing takes care of distributing several requests evenly to different application tiers. It is used to route requests to the right servers and help fulfill the request. Application servers must have an in-built load balancing feature or be able to connect with a load balancing software. Load balancers can also act as a reverse proxy to maintain the load over servers.

**Central management interface:** Applications servers include a centralized management interface that helps a user to manage numerous application servers from one platform, removing the need for many.

### What are the Benefits of Application Servers?

A few benefits of application servers include:

**Instant access to apps:** Every application being used is pulled from an application server and delivered by a web server or a web application server. Web clients make HTTP requests to access a particular app pulled from the application server.

**Traffic optimization:** Application servers are designed in such a way that they can handle high incoming traffic for the apps. They are built to handle multiple requests from web clients. In addition, the performance of heavy applications increases by using an application server.

**License management** : Installing an application multiple times on a system is tedious. This is where the application server comes in. Computers can run applications without the need to be run locally. This helps manage licenses for various applications since only the allowed number of users can use the application at a given time.

**Data integrity:** Application servers follow a centralized approach. Any security updates, patches, etc., can be done via the application server. Different users do not need to access the same application and make changes that could cause errors.

### Challenges with Application Servers

Application servers can come with its own set of challenges, as mentioned below:

**Increase in traffic:** With the boom of the internet and social media, the amount of online traffic has increased drastically. Application servers must keep up with this surge in traffic and ensure no downtime that could affect application performance.

**Network delays:** Network delays can happen due to geographical distance, and applications can take a longer time to load. Assessing the network impact on application server performance when latency increases becomes quite challenging. 

**Technical challenges:** Application servers also face technical issues such as failing to load, problems communicating with hosts, and database connections issues, among others.

### Who Uses Application Servers?

The different personas that would use application servers are:

**IT teams:** IT teams are the main users of application servers. They are in charge of installing, operating, and hosting applications based on the user requirements.

**App developers:** Application servers can be used to provide a container model for applications which makes it extremely important for application developments with Kubernetes. It can also be used to provide services for applications. 

### How to Buy Application Servers

#### Requirements Gathering (RFI/RFP) for Application Servers

Before beginning the buyer journey for an application server, there are a few things to be mindful of, which include the following:

- **Identifying and prioritization:** When choosing application servers, it's essential to identify and prioritize based on the wants and needs of the organization/user. Some important factors include scalability, reliability, development, performance, and cost-effectiveness.
- **Identification of a use case:** If the organization is large to very large, an application server is necessary. However, if a smaller organization is looking to purchase an application server, the cost might be their primary factor.
- **Application modernization:** Application servers can also be used extensively to modernize enterprise applications (JAVA applications) and develop and deliver new cloud-native applications. These applications can usually be supported on-premises, on the cloud, or hosted on containers or Kubernetes.

#### Compare Application Server Products

**Create a long list**

This step involves creating a long list of application server vendors and providers. Some key factors to consider include automation features, network latency, high availability, load-balancing, reading databases, security support, authentication, data privacy, and compliance with open standards such as JavaEE, API gateway support, and others. Keeping these essential features in mind, a long list of products can be generated.

**Create a short list**

Once the long list of application server offerings has been identified, it is time to remove software that does not meet all the business criteria. For this, it is important to use the RFI/RFP made earlier on what is to be done before choosing an application server. Using the above information, buyers can further shorten their list and only select those software vendors that meet all the business requirements.

**Conduct demos**

Once the list has been reduced to a couple of vendors, buyers may begin to request a demo of the application server. The demo on a server will give them an idea of how the software will work once the actual process begins and is an excellent way to ensure the best fit. At this step, the buyer should ask several questions to the vendor about the benefits, after-service support, staff training, and other additional features that can be provided. 

#### Selection of Application Servers

**Choose a selection team**

Choosing the right team to work together on purchasing an application server is a critical part of the process. This team will be in charge of identifying pain points to finally overseeing the entire implementation process. The team should include a mix of different personas who have the required skills, interests, and time. Some corporate roles include project manager, system owner, and decision makers. From the technical team, there should be an IT admin, application developers such as a JAVA/Selenium developer, and DevOps engineering leads.

**Final decision**

Once all the steps are complete, the final decision is made. Weighing all the factors and scenarios, the buyer can purchase the application server software.
