About NetScaler CPX

NetScaler CPX is a container-based application delivery controller that can be provisioned on a Docker host. NetScaler CPX enables customers to leverage Docker engine capabilities and use Citrix ADC load balancing and traffic management features for container-based applications. You can deploy one or more NetScaler CPX instances as standalone instances on a Docker host.

A NetScaler CPX instance provides throughput of up to 1 Gbps.

As a containerized form factor of Citrix ADC, NetScaler CPX integrates well into the Kubernetes environment and forms an integral part of Citrix cloud native solution. Citrix cloud native solution helps you to create and deliver software applications with speed, agility, and efficiency in a Kubernetes environment. Using Citrix cloud native solution, you can ensure enterprise grade reliability and security for your Kubernetes environment. For more information, see Citrix cloud native solution.

This document assumes that you are familiar with Docker and how it works. For information about Docker, see the Docker documentation at https://docs.docker.com.
