Difference between Docker and Kubernetes
Docker is a containerization platform, and Kubernetes is a container orchestrator for container platforms like Docker.
PSPDFKit Document Engine uses the Docker container format. Docker is the most common way to run Docker containers, but there are other technologies to run Docker containers.
Kubernetes is a container orchestrator for container platforms like Docker. It can be used for systems with a higher load, where one Docker container isn’t enough. PSPDFKit Document Engine supports horizontal scaling with running multiple containers of itself. The number of nodes that you can run at the same time are defined in the license agreement. Kubernetes is the most popular orchestrator; however, there are alternatives, such as Docker Swarm.
