Apache Tomcat is a powerful open-source software, widely used and appreciated in the Java-based web application industry. Its primary role is to act as an application server, a program that manages the execution of web applications developed with technologies such as Jakarta Servlet, JSP, and WebSocket, providing users with the requested resources, such as dynamic pages, interactive content, and server-side data processing.

However, Tomcat isn't limited to this; it offers a range of additional features that significantly expand its capabilities. It can be configured to operate behind a reverse proxy or load balancer, easily integrating with other servers and enabling more efficient resource management. This approach improves overall performance, optimally manages incoming connections, and ensures balanced traffic distribution across multiple Tomcat instances.

Additionally, Tomcat supports caching and performance optimization mechanisms, which reduce response times and reduce server load, providing a smoother and more responsive user experience even with a high number of concurrent requests. Thanks to its reliability, scalability, and flexibility, Apache Tomcat is now one of the most widely used solutions for developing and managing Java web applications in production environments.

A distinctive feature of Apache Tomcat is its open source and free nature, making it an extremely affordable solution for companies of any size. Thanks to the absence of licensing fees, Tomcat allows for a very low total cost of ownership (TCO) while offering high performance and great scalability when running Java web applications. Its optimized architecture allows it to handle a high volume of concurrent requests while maintaining rapid response times and minimal resource consumption, making it ideal for complex enterprise platforms, high-traffic sites, and mission-critical applications.

Tomcat is often used in conjunction with a reverse proxy such as NGINX or Apache HTTP Server. In this configuration, the reverse proxy handles incoming requests, load balancing, and connection optimization, while Tomcat handles Java application processing exclusively. This approach allows traffic management to be separated from dynamic content processing, ensuring a robust, high-performance, scalable infrastructure with low operating costs.

Absolutely, Apache Tomcat can be used in combination with other software and components, such as NGINX or Apache HTTP Server, to create a flexible, high-performance, and highly scalable hosting environment. This type of configuration, known as a hybrid architecture, allows you to leverage the potential of different tools, resulting in an efficient, stable infrastructure capable of handling large volumes of traffic.

Tomcat is particularly well-regarded for its ability to run Java web applications developed with Servlets, JSPs, and WebSockets, but it isn't optimized for directly handling large numbers of static requests, such as images, CSS, or JavaScript. For this reason, many Tomcat implementations combine it with a reverse proxy like NGINX or Apache HTTP Server. In this configuration, the reverse proxy receives user requests and decides whether to handle them directly—for example, by serving static files—or forward them to Tomcat, which only handles dynamic applications.

This approach optimizes resource usage: the reverse proxy handles HTTP and HTTPS connections extremely efficiently, while Tomcat focuses exclusively on processing Java application code. This reduces the overall server load, improves response times, and ensures high scalability even during traffic spikes.

Thanks to this integration, companies can obtain a robust, high-performance and secure production environment that combines the speed and efficiency of a reverse proxy with the power and flexibility of Apache Tomcat in managing complex web applications.

On May 25, 2018, the new General Data Protection Regulation (GDPR) came into force, a regulation with which the European Commission intends to standardize the protection of personal data of European Union citizens. The regulation applies to all companies that process data of European citizens, even if they are not based within the Union. Managed Server provides its services by correctly applying the requirements of the new regulation (EU Regulation 2016/679).
