Is Payara a Web Server?

The short answer is no, Payara is not just a web server. It is an application server that includes web server capabilities. In other words, it provides more than just the ability to serve static HTML pages and handle HTTP requests.

Web Servers vs. Application Servers:

To understand why Payara is not just a web server, let’s first differentiate between web servers and application servers.

Web Servers:

A web server primarily handles HTTP requests sent by clients (web browsers) and serves static content such as HTML, CSS, JavaScript files, images, etc. Examples of popular web servers include Apache HTTP Server and Nginx.

Application Servers:

An application server, on the other hand, not only serves static content but also provides an execution environment for dynamic applications. It supports additional features like database connectivity, transaction management, security mechanisms, clustering capabilities, and more.

Application servers are designed to host enterprise-level applications that require complex functionality. Examples of well-known Java EE application servers include Payara Server, WildFly/JBoss AS, and Apache TomEE.

The Capabilities of Payara:

Payara includes all the features of GlassFish Server Open Source Edition, along with several enhancements and bug fixes. It provides a full Java EE 8 certified platform, making it suitable for developing and deploying enterprise applications.

Key Features of Payara:

  • Clustering: Payara supports clustering, allowing you to distribute your application across multiple nodes for improved performance and high availability.
  • Security: It offers robust security mechanisms to protect your applications from unauthorized access.
  • Scalability: Payara allows you to scale your application horizontally by adding more instances of the server to handle increased load.
  • JDBC Connection Pooling: It provides built-in support for connection pooling, which enhances the performance and efficiency of database operations.

In conclusion,

Payara is not just a web server but an application server that includes web server capabilities. It offers a comprehensive platform for developing and deploying enterprise-level Java EE applications. With its robust features and scalability options, Payara is a popular choice among developers.

In this article, we explored the differences between web servers and application servers and clarified that Payara falls into the latter category. We also highlighted some key features of Payara that make it an attractive option for building robust Java EE applications.
