What is Application Server Software for Linux?

Application server software provides a platform for deploying, managing, and running applications, typically for web or enterprise environments. These servers handle the backend logic of applications, facilitating the connection between client devices and databases or other services. Application servers often provide middleware services such as security, transaction management, and messaging, enabling the smooth execution of applications. They are designed to support multiple users simultaneously and ensure high availability, scalability, and performance of applications. This software is commonly used in environments where complex, data-intensive applications are developed, such as in e-commerce platforms, enterprise resource planning (ERP), and customer relationship management (CRM) systems.
