Rakendusserverien

Rakendusserverien, or application servers, are software frameworks designed to provide the business logic for end-user applications. They are a type of middleware that supports the development and delivery of dynamic web applications. Application servers manage and host applications, making them accessible to clients through various protocols. They handle tasks such as processing client requests, executing business logic, interacting with databases, and managing resources like threads and connections.

These servers bridge the gap between the web server, which typically handles static content and initial request routing, and the backend databases and other enterprise systems. By centralizing application logic, they promote code reusability, improve performance through features like connection pooling and caching, and enhance security by providing a controlled environment for application execution. Common examples of application servers include Apache Tomcat, JBoss/WildFly, Oracle WebLogic, and IBM WebSphere. They are crucial components in many enterprise architectures, enabling the creation of scalable and robust applications.
