Compare the Top Application Delivery Controllers (ADC) for Linux as of October 2025

What are Application Delivery Controllers (ADC) for Linux?

Application Delivery Controllers (ADCs) are software solutions designed to optimize the performance, security, and availability of applications delivered over the internet. They manage traffic between users and applications by distributing it across multiple servers, ensuring load balancing and preventing overloads. ADCs also provide security features like SSL offloading, DDoS protection, and web application firewalls to safeguard applications from attacks. By improving application response times and ensuring high availability, ADCs enhance user experience and help maintain service continuity. They are commonly used in data centers and cloud environments to ensure efficient and secure application delivery.

    NGINX Unit
    An universal web app server that combines several layers of the typical application stack into a single component. NGINX Unit simplifies the application stack for web apps and APIs by combining several layers of the typical stack into a single component. NGINX Unit is a universal web app server, intended as a building block for any web architecture regardless of its complexity, from enterprise-scale deployments to your pet's home page. It is equally suited to simplifying modern microservices environments as it is to modernizing legacy and monolithic applications. NGINX Unit was created by the original NGINX team on an all-new, open-source codebase. The architecture incorporates insights from over a decade of running the world’s most popular web server. Unlike the NGINX web server, NGINX Unit uses a multi-process, multi-threaded architecture. The NGINX web server is often deployed as a reverse proxy in front of web applications. NGINX Unit can run the application code natively.
